Our most popular model is the CT Cryogenics CT-20, a mid-size liquid nitrogen tank holds 20 liters of liquid nitrogen and 1284 bulk .5ml straws of semen with a holding time of 140 days between liquid nitrogen refills.

It includes a free padded insulated cover that helps to protect the tank from damage and reduces liquid nitrogen evaporation. The price shown includes the 6 canisters and the insulated cover. We think this is the best value on a liquid nitrogen tank available today!
