What are the factors affecting semen quality in liquid nitrogen tanks?

Editor:adminClick: Time:2019-10-16 09:16
When semen is stored in a liquid nitrogen tank, it can not be ignored, because there are many external factors that can affect the quality of semen, such as the temperature at the neck of the liquid nitrogen tank.
1. The temperature of the neck of the liquid nitrogen tank is different in different shapes and sizes. Generally speaking, the temperature of the neck of the liquid nitrogen tank with short neck opening is lower than that of the tank with long neck opening.
2. The level of liquid nitrogen in liquid nitrogen tank will affect the temperature of neck. The results show that the temperature difference of 40 C at 11CM away from the neck can be caused by the change of liquid nitrogen content in the tank, which can reach - 130 C below 300px.
Summary: The frozen semen should be extracted with tweezers below 300 PX from the neck, not by hand directly above 300 px.
