The liquid can cause severe injuries or death. 2019, Enfermedades emergentes en porcino - Albitar - N222, Ene-Feb. 2019, Improving the pet owner experience in your practice - Veterinary Focus - Special Issue, Steps for Freezing Bovine Semen: From Semen Collection to the Liquid Nitrogen Tank, Occupational Health in Animal Care, Use and Research, Laboratory Animal Medicine and Management, Prevention of Viral Diseases, Vaccines and Antiviral Drugs, Prions and Transmissible Spongiform Encephalopathies, Families with Viruses of Minor Veterinary Significance, Understanding Cryogenic Liquid Nitrogen Tanks. It is an important component of all living tissues and amino acids. When inhalation of nitrogen is excessive, symptoms such as dizziness, nausea, vomiting, loss of consciousness and death can happen. 2) are Dewar flask containers designed for transportation of frozen biological specimens (semen or embryos) in LN2 vapor at temperatures around -190C. 2023 International Veterinary Information Service, All content that was recently added to the IVIS library, The animal reproductive industry has been using liquid nitrogen (LN, ) tanks to freeze and store frozen semen for several decades. Centralized cryogen storage tank for oxygen in use at a hospital. Cryogenic liquids or "Cryogens" are liquefied gases that have been cooled below ambient temperature, pressurized, and kept in their liquid state at very low temperatures. Also, do not attempt to move an off gassing cylinder; allow it to purge until empty. 0000004234 00000 n : Semen storage tank with a measuring stick for LN. The inner container is only attached to the outer container at the neck and a crack in this connection will cause the tank to quickly fail! This type of oxygen monitor activates when the oxygen concentration reaches below the set point, which is normally 19% or 19.5% O, is capable of causing instant frostbite on contact with living tissue. Many people may be heading to the Ohio Beef Expo to pick up straws of semen and there are some things you should keep in mind. If flow seems to be mostly vapor and squeals loudly, the tank is almost empty or completely empty. This effect happens when somebody dips a wet finger in molten lead or blowing out a mouthful of liquid nitrogen, both situations causing no injuries to the demonstrator.The best practice to prevent frostbite when handling LN2is to wear personal protective equipment such as a full-face shield over safety glasses, loosefitting thermal insulated or leather gloves, long sleeve shirts, and trousers without cuffs. 7). Clean the tank after use and store in a clean place. Each canister is 79 mm in diameter and contains only one 65 mm diameter goblet full of 0.5 ml straws located at the bottom of each canister. This means that ten 0.5 ml straws can be stored per aluminum cane using 2 goblets (, ) and that several full aluminum canes are required to fill each canister (, ). 1. D Neck tube. In the marketplace, there are dry shippers with static holding times that vary between 8 and 24 days. They are made of aluminum and have two separate chambers: an inner and an outer chamber (. (Left picture obtained from the MVE SC Series - Aluminum Storage Tanks catalogue, Chart Industries, Inc). 0000011441 00000 n Nitrogen constitutes 78.03% by volume and 75.5% by weight of the Earths atmosphere making it the largest single component of the air. E Annular filling lines. The valve will then open and vent gas to the atmosphere. The goblet containing yellow straws is 10 mm in diameter; the one having red straws is 13 mm in diameter; the one with transparent straws is 35 mm in diameter; and the one with blue straws is 65 mm in diameter. Round goblets are usually classified and differentiated by their diameter in millimeters (mm) (Fig. B - Locking tab. Right: Top view of the same storage tank after removing the lid. With 2-level bulk storage, the tank capacity can be increased by 2 or 3 times, when compared with storage on aluminum canes. 6 goblets X 250 straws (0.5 ml) = 1,500 straws (0.5 ml), 6 goblets X 550 straws (0.25 ml) = 3,300 straws (0.25 ml). If you want more accurate measurements, try a gauge that uses differential pressure of determine liquid levels. The following are important procedures to ensure maximum holding time in a LN. The explanation for this discrepancy may be that a 1 or 2 mm larger goblet (54 or 55 mm goblet) was used in the original capacity calculation allowing for storage of more straws per goblet/canister, or it may be that the capacity for the 53 mm goblet was a conservative estimate and it could have actually stored more straws than we calculated. . liquid nitrogen container for sale, Quality YDS-20 nitrogen containers,liquid nitrogen tank,liquid nitrogen dewar on sale of Qingdao Baigong Industrial and Trading Co., Ltd from China. For safe, accurate N chemigation, follow these steps each time you apply N: Check travel time of the irrigation system at the desired water application depth and recalculate the chemical injection rate for the planned amount of nitrogen. Ideally this would be daily but even if you could remember to do it once a week you might get an indication when the nitrogen use on a tank has increased so that you can move the semen to another tank. The dry shippers must be properly charged by filling with LN, to the point of saturation of the absorbing material and then removing the excess LN, to provide maximum holding time. Schipma MJ, Wang X, Fowler H, et al. 12). The liquid nitrogen capacity for dry shippers varies between the different models available; this usually ranges between 1.5 to 7 liters of LN2. A Offset neck design. This type of container has valves for filling and dispensing the cryogenic liquid, and a pressure-control valve with a frangible (bursting) disk as backup protection. What is the optimal number of eggs at oocyte retrieval? According to these calculations, when using one 53 mm goblet per canister, the 1 level bulk maximum storage capacity of the tank could not be reached. is very useful in a wide range of applications as an open-cycle refrigerant and cryoprotectant including: Immersion freezing and transportation of food products. During transfer, if pressure in the tank is higher than the normal liquid withdrawal pressure, open the Vent Valve to lower the pressure. 2. . At low oxygen and high nitrogen concentrations, unconsciousness and death may occur in seconds and without any warning. One: Appearance The volatilized liquid nitrogen tank is free of defects, such as welding seams, spray paint, etc., so that the vacuum rate can be guaranteed. 10). For complete guidance on the safe storage and handling of cryogenic materials, see the following SOP in the Chemical Hygiene Plan: SOP: Cryogens and Dry Ice. We need to take care of these tanks to make sure we dont lose the contents. If you must routinely take your tank between farms, make sure it is strapped down where it will not tip. First determine how many aluminum canes can be stored per canister without being jammed. The gauge that measures the liquid levels is most likely a simple float and can get stuck at "full". During the manufacturing process, a vacuum is drawn in the space between these two containers. The canister can contain a maximum of 1 bucket (1000 mB) of Liquid Nitrogen.Vanilla buckets and other liquid receptacles in Minecraft cannot be used to hold Liquid . These cylinders can operate at pressures ranging between 22 and 350 psi. C Aluminum wall. A - Aluminum wall. It is important to know that soaked clothing or cotton can cause more rapid skin damage than a spill of direct LN. This means that each aluminum cane can store a maximum of 14 (0.5 ml) straws or 28 (0.25 ml) straws. Liquid nitrogen tanks are generally made from four main types of material. Answer (1 of 2): Liquid nitrogen tanks have bleed valves so that they don't explode. Uterine : Measuring gauges that are normally found in a LN, cylinder. Now, liquid nitrogen cylinders are normally fairly benign, as long as you don't freeze your external organs off with the stuff or leave the liquid sitting around where it can condense oxygen out of the air. 30(3), December 2020, COVID-19, Special Practice Management - Veterinary Focus - May 2020, The C-Factor: Vet Skills in Communication - Veterinary Focus - Mar. E Hydrophobic absorbent material shown in blue. Dean Kreager, Licking County Agriculture and Natural Resources Educator. of 1/2 cc straws (10 per cane): 1,260. LN2 tanks are constantly venting, and if nothing is coming out of the vent/gas/liquid lines then the tank is most certainly empty. tank level should be checked weekly and recorded in a LN. There are times my tank is just outside of my working system when I am breeding cows. D Neck tube. Laboratories primarily use these small containers for temporary storage. on sale of Henan Tianchi Cryogenic Machinery Equipment Manufacturing Co., Ltd. from China. Comparison of size and capacity of different plastic goblets used to store semen straws in storage tanks. Lab & Life Sciences, This can be a float-type gauge that provides an approximate indication of the tanks contents. But use a drip tray or pan to avoid water damage. Does anyone have any ideas what might be going on? The Pressure Control Valve is mounted on the same stem as the Pressure Gauge. This means that the storage capacity of the tank when full is at least: To store this amount of straws, the user will require 90 aluminum canes and 180 goblets (10 mm diameter).Bulk storage. Would to like to further discuss this item? 0000007298 00000 n Goblets are normally round in shape, although there are other shapes available, such as polygonal, hexagonal, etc. At this point, the regulator allows gas from the top of the tank to flow through the internal vaporizer out of the Gas-use Valve to the your target system. Note: Precautions should be taken when attempting this method. More recently with the rapid development of embryo transfer technology in different species, it is being used for storing frozen embryos. 0000009395 00000 n The larger goblets (35, 39, 42, 53 and 65 mm) do not require canes and are placed directly inside the canister (Fig. 20. Pour into the liquid nitrogen tank with warm water at 40C-50C or with a neutral detergent, and then wipe it with a cloth. So there's plenty of room to set weight limits for alarm notification of e-mail, text, and phone regardless of sample movement. But idiocy will find a way - note the regular cylinder on the right and the new, improved model next to it. Would you like to add this to your library? trailer tanks should be located in an area that allows daily visual observation. One of the canisters has been retrieved to the center of the tank to show 7 aluminum canes (with 10 mm diameter goblets) located inside the canister and with extra room for storing more cane units. Jennifer Bakkensen, M.D. Fertility and Sterility On Air is the podcast where you can stay current on the latest global research in the field of Reproductive Medicine. Laboratory dewars have wide-mouthed openings and do not have lids or covers. Emptying a liquid nitrogen tank. How do you clean a liquid nitrogen tank? According to WHMIS, cryogenic liquids are "compressed gases". Flush with water. Add diluted bleach and let sit at least one hour, but not more than 2 hours. Slowly turn on the tank valve to begin flow of liquid nitrogen. Two level bulk means that two goblets full of straws are used in all the canisters, one on top of the other (Fig. A unique lid is used to plug the neck tube and create further insulation for the liquid nitrogen in the interior of the tank. It is the amount of time that the dry shipper will be capable of storing the specimen in LN2vapor at the required temperature (-190C) during transportation. In this case the tank is empty with no pressure inside. F Insulation shown in yellow. School of Medicine and the Rush University The vacuum nozzle on the liquid nitrogen tank, the seal of the quiet valve, and the lead seal cannot be damaged. The dry shippers must be properly charged by filling with LN2to the point of saturation of the absorbing material and then removing the excess LN2to provide maximum holding time. This is a measure of the maximum amount of straws that can be stored in a dry shipper for transportation. The tanks storage capacity will depend on the size of these canisters, the type of straw being stored (0.5 or 0.25 ml straws), and whether or not the straws are packaged on aluminum canes. Thanks for the input. neck fracture or loss of vacuum), frosting formation on the tanks neck can be observed and corrective measures must be taken quickly. Since cryogenic liquids are actually liquefied gases, pressure within the tank will constantly increase as the laws of physics transform the cold liquid into warmer gas. Never touch non-insulated vessels containing cryogenic liquids. 5. Time to Prepare and Prevent, Frost Seeding Season is Here, or, Almost Over. 3). If you need to know exactly how much liquid is in your cylinder, use a Digital Gauge. 14) are insulated, pressurized, vacuum-jacketed vessels that are commercially available with volume capacities that can vary from 35 liters up to 450 liters. Continue to ll our tank until the liquid nitrogen is about 2 inches below the insulating neck of the tank. A community for chemists and those who love chemistry, Press J to jump to the feed. Mating Capacity of Bulls; Bull to Cow Ratio, Be Aware when Feeding Ionophores to Cattle an Overdose May Prove Deadly. Good luck, Latexman Nitrogen, Direct skin contact with LN, causes severe frostbite (cryogenic burns) within moments to seconds depending on the form of liquid nitrogen (liquid vs. mist) and surface area of the nitrogen-soaked material. J Insulation shown in yellow. 0000006842 00000 n Notice top and bottom location of the goblets in the cane. Because, most of the time, things are good. A Offset neck design. is to wear personal protective equipment such as a full-face shield over safety glasses, loosefitting thermal insulated or leather gloves, long sleeve shirts, and trousers without cuffs. Each canister is 79 mm in diameter and contains only one 65 mm diameter goblet full of 0.5 ml straws located at the bottom of each canister. 0000025030 00000 n The total capacity of this tank, using 65 mm goblets in 2-level bulk storage in 6 canisters would be approximately 4,380 (0.5 ml) straws. Andy Castiglione is part of the 3rd generation of the Castiglione family to manage and grow WestAir. This tank has six canisters that are enumerated individually and can be seen in the interior of the tank. Because of this asphyxiation hazard, when working with LN, in a confined or enclosed space it is recommended to monitor oxygen concentration with specialized ambient oxygen monitor-alarms that are available in the market (, . Right: Semen storage tank with a measuring stick for LN2. Interior schematic view of a dry shipper. The tanks storage capacity will depend on the size of these canisters, the type of straw being stored (0.5 or 0.25 ml straws), and whether or not the straws are packaged on aluminum canes. Do not store directly on concrete. Often set to open at 230 psi, the Pressure Control Valve works in conjunction with a Rupture Disc in the inner tank. Figure 9. 210 0 obj <>stream The drying method can be natural air drying or hot air drying. Volume: 10L, Neck diameter: 50mm, External diameter: 305mm, Height: 550mm, Empty weight: 6.3kg, Liquid nitrogen storage: 85-110days,. Left: Interior schematic view of a 6 canister semen/embryo storage tank with the inner chamber with LN2shown in blue. 10). What happens in the ensuing decades will briefly be exciting. The Economizer Circuit come into action when the pressure reaches 100 40 psi. We have all seen what happens to metal items exposed to manure for long periods of time. Weighing method: We need to first find and weigh the empty tank with the same volume specifications as the liquid nitrogen tank, or understand the weight of the empty bottle marked on the bottle. Now, liquid nitrogen cylinders are normally fairly benign, as long as you don't freeze your external organs off with the stuff or leave the liquid sitting around where it can condense oxygen out of the air. If it is damaged, the vacuum level will be reduced. It is produced industrially in large quantities by fractional distillation of liquid air. If you have trouble accessing this page and need to request an alternate format, contact u@osu.edu. Because of this asphyxiation hazard, when working with LN2in a confined or enclosed space it is recommended to monitor oxygen concentration with specialized ambient oxygen monitor-alarms that are available in the market (Fig. When using aluminum canes, it is important to remember that five 0.5 ml straws can be stored in a 9.2-mm goblet, and that one aluminum cane can hold two 9.2 mm goblets (top & bottom level). 6).The inner chamber is the area that stores the LN2and contains the frozen specimens, and is actually held from the outer shell by the neck tube (Fig. The other issue that you may not think about is that nitrogen gas is constantly escaping. (Top picture obtained from www-safety.deas.harvard.edu/services/nitrogen.html). This reduces pressure in the inner tank and minimizes losses from venting. 9). Interior schematic view of a dry shipper. Unfortunately, when somebody aspirates air with higher concentration of nitrogen gas than normal, the carotid body works relatively slow and this low-oxygen concentration sensing system (hypoxia) will not react in an efficient way to prevent potential asphyxiation. F Lid or plug. Observation of the interior of a semen storage tank. Inspect performance of the check valves, low-pressure drain, low-pressure shutdown switch and all fittings . (Picture obtained from Alpha Omega Instruments website). If you don't use the a cylinder for several days, pressure will continue to rise at a rate of 30 psi per day because a small amount of heat will leak into the inner tank. storage tanks can keep semen and embryos at -196C. Example of an oxygen monitor to measure ambient oxygen concentration in confined rooms. A unique lid plugs the dry shippers neck tube, helping to create the insulated interior environment of LN, from spilling by ensuring the system remains upright at all times (. The static holding time depends on the LN, evaporation rate of the tank, which is calculated in liters evaporated per day (liters/day). Because it maintains temperatures far below the water freezing point, LN. As a rule of thumb, the manufacturers calculate the maximum storage capacity of tanks by using only 0.5 ml straws. The liquid nitrogen capacity also varies between the different storage tank models available in the market place. Cryogens will create high gas pressures inside the storage containers, and therefore they require a relief vent/valve to allow the gases to escape from the container. It is also sensitive to changes in pH and temperature. liquid nitrogen tank for sale, Quality What brand of liquid nitrogen tank is a good liquid nitrogen storage tank manufacturer? Its properties are listed in the following table. Capacity (English) 1.765 cu. These are called dry shippers because they should not have liquid in them. Dewars are non-pressurized vessels, like a Thermos Bottle. To locate and identify bulk stored semen, the visible portion of the canister handle is labeled and the information recorded. Death may happen from errors in judgment, confusion, or loss of consciousness that prevents self-rescue. Last week I talked about proper semen handling so this week I thought it was worth providing some information on care and handling of the liquid nitrogen tanks. On the other hand, some companies report maximum storage capacity of a tank as "Bulk storage" in 1 or 2 levels. The larger the diameter of a round goblet, the higher the straw storage capacity will be (. The entire valve dislodged from the cylinder causing a violent release of liquid nitrogen from the cylinder. Place your liquid cylinder and/or its vaporizer on a pan or tray to catch the water as the frost evaporates. Left (a): View of a 65 mm plastic goblet showing its high storage capacity, around 365 (0.5 ml) straws. If a LN2 tank does fail, it presents a considerable suffocation hazard. 8) and that several full aluminum canes are required to fill each canister (Fig. 0000024952 00000 n In this type of storage, a much larger plastic goblet with a diameter very close to the internal diameter of the canister is used to store the straws (, ). When pressure normalizes, the Economizer Regulator closes and the cylinder then deliveries gas by drawing liquid through the Vaporizer Circuit. Liquid Nitrogen A second option is to install a liquid nitrogen storage tank on your site and get it filled up periodically by a gas company. Left: Picture of a semen/embryo storage tank with a LN2capacity of 22 liters and holding time of 40 days. B Top. Liquid cylinders let you withdraw liquid and/or gas. Coolant during machining of high strength components. ). The Pressure Gauge is probably the one you will look at first and refer to most frequently. 0000003007 00000 n Storage tanks are large, metal, vacuum-sealed liquid nitrogen refrigerators encased within an extremely efficient insulation system. Giving it a heft is a good test for this. Liquid nitrogen is used to perform the freezing procedures with computerized freezers in order to achieve final temperatures colder than -80C and ranging between -80C and -196C. COVID-19 vaccine and infertility: baseless claims and unfounded social media panic, 70th Annual Meeting of the Pacific Coast Reproductive Society, Cover image is adapted from a poster presented A liquid nitrogen tank is a double-walled container in which two tanks are fused together with a fiberglass neck (Figure 1). 0000005286 00000 n Thank you, your email will be added to the mailing list once you click on the link in the confirmation email. The static holding time for storage tanks is measured in days and is used to calculate how often the tank needs to be refilled with LN2and their estimated working time. G- Rack stand. 6). If you look at the picture you can see that the inner container is only attached to the outer container at the neck. This type of oxygen monitor activates when the oxygen concentration reaches below the set point, which is normally 19% or 19.5% O2. The Economizer Circuit minimizes product loss. They contain an absorbent material that soaks up the liquid nitrogen and can maintain a temperature close to the temperature of liquid nitrogen for 1 to 3 weeks. Canadas National Occupational Health & Safety in: www.ccohs.ca/oshanswers/chemicals/cryogenic/cryogen1.html. Many people use the word dewar to describe a liquid cylinder, and vice versa. ), the cryogenic fluid used in the reproductive industry, is inert, colorless, odorless, non-corrosive, non-flammable, and extremely cold. On the right of the picture is a 50 liter LN2cylinder (22 psig) connected to the IceCube freezer through an especially designed connecting hose. He works hard to bring the slogan "Large Enough t ratory dewars have wide-mouthed openings and do not have lids or covers. LN2 Supply Tank. Generally a single stage regulator is attached directly to the Gas-use Valve to reduce the supply pressure to match your applications requirements. Liquid cylinders are pressurized containers specifically designed for cryogenic liquids. The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than its boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly. Measure the nitrogen level and keep track of it. The canister is 79 mm in diameter and contains two 65 mm diameter goblets full of 0.5 ml straws, locating one goblet on top of the other inside each canister. If anyone has any info on how the internals work on these or any other insight that would be great. These modern displays also contain graphical digital displays to give you precise measurements. But for most applications, the pressure inside the tank must be artificially maintained. Legally you can not carry a tank containing liquid nitrogen in an enclosed vehicle such as a truck cab or car. Hazards associated with Liquid Nitrogen Asphyxiation In case of tank failure (i.e. Ideally, the LN, level should be monitored every week with a calibrated plastic measuring stick (, and contains the frozen specimens, and is actually held from the outer shell by the neck tube (. Until now, it was assumed that once avalve froze, the tank must be allowed to purge orit could rupture. The vacuum increases the insulating effect and is the major effective property of the tank. : Interior schematic view of a 6 canister semen/embryo storage tank with the inner chamber with LN. Plus they often have the intelligence to eliminate the need for lookup charts. The ideal scenario is to have the LN, tank filled between half and full capacity. The best way to use liquid nitrogen is to create small droplets on the surface of the liquid using a spray bottle. The Gas-use Valve allows gas to flow from the tank. Then open the Liquid-use Valve to allow head pressure in the tank head to force liquid up to withdrawal tube, and out the Liquid-use Valve. On the right of the picture is a 50 liter LN. 0000005827 00000 n This can happen very quickly if nitrogen spills inside the vehicle. Dewars should be covered with a loose fitting cap to prevent air and moisture from entering and allow for pressure release. Damage to the materials with which the dewar is made could put stored objects at risk. This is a measure of the maximum straw holding capacity of the storage tank. Therefore, the storage capacity will depend on the size of the canister, the type of straw being used (0.5 or 0.25 ml straws), and whether or not the straws are packaged on aluminum canes. It is an important component of all living tissues and amino acids. This video covers the filling and maintenance of liquid nitrogen tanks. But what I can say is the 3 I come in to contact with almost daily always tell me they are empty. Facility at Northwestern University Feinberg Figure 1. on Sep 14, 2017. This slide show is worth the price of admission:. The static holding time depends on the LN, evaporation rate of the shipper, which is calculated in litters evaporated per day (liters/day). shown in blue. I'm sure I forgot something important. 0000004704 00000 n The static holding time for these tanks varies considerably, and it may be as low as 17 days or as long as 340 days. Both have a capacity of 50 liters of LN2. C Aluminum wall. When appropriately insulated from ambient heat, LN2stays at -196C or -320.5F, which is the nitrogen boiling point. Two goblets (53 mm diameter) are stored per canister instead of only one. 12and Table 1). Cutout view of a liquid nitrogen semen storage tank showing insulation and cannisters. of 1/2 cc straws (1 level bulk): 1,764. B - Locking tab. hb`````mc`e`gb@ ! First determine how many aluminum canes can be stored per canister without being jammed. 0000001371 00000 n These tanks can also be used in frozen semen banks. Dry shipper container commonly used for transport of frozen semen or embryos. Empty Weight: 2.8kg Liquid Nitrogen Container: Static evaporation: .1L/day: Height: 370mm: Color: In general, goblets are usually not packed to maximum capacity for storage purposes.An alternative for more storage in a tank is to use 2level bulk storage. The recommended minimum volume of LN2present in the tank is at least 5 cm (2 inches) in order to prevent any damage to the stored specimens. Figure 5. 5) that vary in diameter and height depending on the tank model. The end result will be an empty tank (or perhaps an empty remnant of . ). Thus 2/3 of the weight of a full tank is liquid nitrogen. In general, the LN2 capacity for the storage tanks used on farms, in veterinary clinics or by artificial insemination, technicians can range between 3.6 to 50 liters depending on the model and the manufacturer (Fig. . Medicine Scientific Congress & Expo provided by The human carotid body, located near the bifurcation of the carotid artery, is an anatomical organ that measures changes in blood pressure and the composition of arterial blood flowing past it, including the partial pressures of oxygen and carbon dioxide. Some tips and tricks for using liquid nitrogen: - Fill an empty spray bottle with liquid nitrogen Open the liquid nitrogen valve and allow liquid nitrogen to empty into our tank. At the same time, the evaporation rate depends on the dry shippers LN, capacity measured in liters and the size of the neck opening. But when things go bad (you unexpectedly run out of liquid, liquid stops flowing, or your floors get water damaged), the more familiar you are with the operations and maintenance of your dewars and liquid cylinders, the faster you can make things better. Cryogenic liquids have boiling points below -150C (-238F). Please enter a term before submitting your search. When using aluminum canes, it is important to remember that five 0.5 ml straws can be stored in a 9.2-mm goblet, and that one aluminum cane can hold two 9.2 mm goblets (top & bottom level). tanks are a tool that farmers, artificial insemination technicians, embryo transfer practitioners, veterinarians, animal reproductive scientists, semen banks and researchers use everyday, this paper has been written to provide a basic knowledge and understanding of this amazing product and how to use it carefully and more efficiently. The problem is that these tanks will cost as much or more than your standard storage tank and you need to recharge them with liquid nitrogen before using them.
