The embryo storage tank is composed of two layers: an inner and outer bladder. The inner and outer layers are insulated by a vacuum. It has good thermal insulation and can reduce liquid nitrogen consumption. Even so, the liquid nitrogen balance and temperature in the tank need to be tested every day to ensure that the ambient temperature of the cryopreserved embryos is normal and stable.
In order to ensure the safety of the embryos and improve work efficiency, we can install a liquid level alarm, which can detect the liquid level in the tank. When the ambient temperature reaches the upper and lower limits, an alarm will sound to remind the staff to replenish liquid nitrogen in time. It also supports text messages. , telephone, and email alarm functions. The addition of a liquid level alarm can avoid embryo loss caused by insufficient liquid nitrogen.
