Because of the storage of liquid nitrogen, the container for long-term storage of biological samples is called “liquid nitrogen storage tank“. It can also be called sample storage tank and cell storage Dewar. The larger the model, the more it is used in the laboratory.
Which models and configurations are there?
Common liquid nitrogen storage tank models range from 1 to 175 liters, and are basically made of aluminum alloy, with double tanks for vacuum storage of liquid nitrogen.
Most of the cells used in the laboratory are stored cells, which need to be equipped with cryopreservation racks and freezer boxes, and the convenience of extraction should also be taken into account, which are generally large-opening containers. Commonly used models are basically above 30 liters and 125, that is, in the range of 30 to 175 liters.
The more widely used are:
YDS-47-127, comes standard with 6 square buckets, that is, cryopreservation racks, 1 lock cover, 1 protective cover and 1 neck plug;
YDS-50-125, the configuration is also 6 square buckets, each with a lock cover, a protective cover, and a neck plug;
Relatively large laboratory liquid nitrogen storage tank models are:
YDS-65-216, 4 square buckets; YDS-65-216L, with 6 square buckets;
YDS-95-216, 6 5-layer square buckets; YDS-115-216, 6 square buckets, the number of layers is also 6;
Larger laboratory liquid nitrogen tanks:
YDS-120-216, can hold four 10-layer square pails;
YDS-145-216, six 8-layer square buckets; YDS-175-216, six 10-layer square buckets!
The larger the model, the more storage. Except for the square bucket, all laboratory liquid nitrogen storage tanks have buckets/lock caps/protective sleeves.
