2. Determine the amount of frozen sample, diameter and volume required

 

The amount of frozen specimens will determine the volume of the liquid nitrogen tank. For small specimens, choose a small liquid nitrogen tank.

 

If you need long liquid nitrogen storage, you can choose a liquid nitrogen tank with a volume of 30 liters or 35 liters and a diameter of 50 mm for storage. The static storage time of liquid nitrogen is more than half a year.

 

If the specimen is large in volume, it is necessary to select a liquid nitrogen tank with a large volume. If a small volume liquid nitrogen tank is purchased for freezing, the specimen will occupy the space inside the liquid nitrogen tank, and the liquid nitrogen tank can only contain a little liquid nitrogen, thereby reducing The number of days in which liquid nitrogen is stored may cause necrosis of frozen specimens due to lack of liquid nitrogen.

 

The size of the specimen is also critical for the selection of liquid nitrogen tanks. Generally, the diameter of the liquid nitrogen tank should be larger than the diameter of the frozen specimen. For example, if your specimen is 90mm in diameter, and you have purchased a liquid nitrogen tank with a diameter of 80mm, your specimen will not fit in and will not meet your needs. .

 

There are two kinds of buckets inside the liquid nitrogen tank, one is a round bucket, which can be used to place larger tissue-like or large-capacity cryotubes. The other is an extractable bucket, which can be placed in a standard 2ml cryotube for storing cells and other products.
