20 l liquid nitrogen biological container with large diameter

20 l liquid nitrogen biological container for animal husbandry are mainly used as biological containers for frozen storage of semen of cattle, sheep, rabbits, pigs and other livestock. They should be cleaned in time after use to prevent foreign bodies from corroding the tank and affecting the low temperature effect.

Product structure and advantages of liquid nitrogen tank for animal husbandry

1. Both the outer and inner liners are made of highly corrosion-resistant aviation aluminum alloy, which is solid and durable;

2. The neck pipe is made of epoxy glass pipe reinforced plastic, which not only has high strength, low thermal conductivity, but also reduces the evaporation rate of liquid nitrogen;

3. Between the outer tank and the inner tank, the insulating material is filled, and the space gas is pumped out, which is in high vacuum state;

4. The cover plug is made of special plastic, which meets the requirements of liquid nitrogen tank;

5. Key points: please do not wrestle, screw or pat the vacuum suction nozzle, which is as big as a button, or the container will be scrapped.

Precautions for liquid nitrogen tank for animal husbandry:

1. The workplace should be ventilated. In particular sealing area, excessive nitrogen composition will lead to a small proportion of oxygen and suffocation of operators;

2. Before filling liquid nitrogen, please fill a small amount of liquid nitrogen in the tank first, and then fill it after placing for a while; if the tank is filled directly without precooling, the tank temperature will not be able to adapt at once, which is easy to be damaged;

3. When the residual liquid nitrogen is 1 / 3 of the total volume, it is necessary to replenish liquid nitrogen in time in order to avoid the loss of biological activity of biological samples.
