In breeding farms, animal reproduction is inseparable from frozen semen. A certain amount of frozen semen is stored in every farmer's home. These frozen semen like to live in low-temperature environments. Once exposed to normal temperature, they may become inactive and lose the ability to reproduce. Therefore, the preservation of frozen semen cannot be careless! For this reason, farmers will choose liquid nitrogen frozen semen tanks as containers for storing frozen semen because it has the advantages of heat preservation and insulation. With the help of liquid nitrogen, it can keep the interior in a stable low-temperature environment and at the same time isolate the outside heat from entering. However, there are bugs in using liquid nitrogen to preserve frozen semen. It is volatile and requires constant attention to the amount of liquid nitrogen in the tank. If the margin is insufficient, the safety of frozen semen will be threatened. Therefore, when the remaining liquid nitrogen cannot cover the frozen semen, it needs to be replenished in time. So the question is, how long can a liquid nitrogen tank store liquid nitrogen? When should I replenish liquid nitrogen? It depends on when the liquid nitrogen will be used up! Under the premise of consistent capacity, caliber plays a decisive role! According to the rules of the liquid nitrogen biological container industry, the larger the diameter, the shorter the storage time, and the opposite is true for small diameters. Letâ??s take a 30-liter liquid nitrogen tank as an example. 50mm small diameter, liquid nitrogen static storage time is 260 days; 80mm small diameter, liquid nitrogen static storage period of 150 days; 125mm large diameter, static storage in liquid nitrogen for 90 days; 210mm large diameter, static storage in liquid nitrogen for 49 days! Therefore, when the liquid nitrogen frozen sperm tank is 30 liters and 125mm, liquid nitrogen needs to be replenished every 90 days; if it is 30 liters and 210mm, liquid nitrogen needs to be replenished every 40 days! In addition, please note that static storage time â? usage time! Static storage refers to the state of being filled with liquid nitrogen and not being opened or used. This is only the reference data provided by the manufacturer to the user. As for the dynamic consumption of liquid nitrogen, each userâ??s opening frequency and the dwell time each time the lid is opened are different, so it is impossible to Calculate accurately and provide reference. The safe way is to fill up the liquid nitrogen once, use it once and record it to determine your own dynamic storage time. Also, donâ??t forget to ensure that the liquid nitrogen always covers the frozen sperm, so that the spermâ??s vitality is guaranteed!
