Sperm forever "youth" of the secret

 

 

After collecting the semen, take a small amount to do a sample check, the rest of the added protection agent, Meiling biological medical liquid nitrogen tank (-196 ℃) frozen up. When needed, the sperm sample tubes are thawed in a 37 ° C water bath.

 

Liquid nitrogen tank temperature is -196 ℃, this time sperm metabolism at a minimum level, reduce metabolism can be long-term survival. In theory, these sperm samples can be stored in liquid nitrogen tank for several years, decades or even a hundred years.

In order to ensure the safety of umbilical cord blood, the liquid nitrogen reservoir is equipped with 24-hour closed-circuit monitoring, infrared alarm, dual-circuit power supply and the liquid nitrogen level of 24 hours monitor.

 

Meiling Bio-medical liquid nitrogen tank and wireless intelligent monitoring system with the perfect, in the sperm, embryos and umbilical cord blood and other storage process, can effectively monitor the biological samples in the tank to protect biological samples of the safety and stability.
