Internal layout of the cryogenic liquid nitrogen freezer

Not only liquid nitrogen tanks but also cryogenic liquid nitrogen freezers are available for the storage of experimental samples!

Liquid nitrogen freezers and liquid nitrogen tanks share a similar freezing principle, both using liquid nitrogen as the “freezing agent”, but the differences lie in the type and amount of samples stored, the material used for the containers and, more importantly, the internal layout, which directly affects their mode of operation!

Here, we will take the tianchi cryogenic liquid nitrogen freezer as an example and talk about its internal layout.

The interior of the tianchi cryogenic liquid nitrogen freezer can be simply divided into two areas, the upper part is the sample storage area and the lower part belongs to the liquid nitrogen placement area, with a large tray separating the two areas.

The samples are stored dry, unlike conventional liquid nitrogen tanks where the samples are mixed with liquid nitrogen, which is safer and less prone to cross contamination.

The sample storage area can also be zoned according to the number and type of samples to be stored, and divided into 4 or 6 equal sections using a carrying tube or lyophilisation rack. Each small area has a unique number, which is placed on a rotating bearing to facilitate the differentiation of the frozen samples.

In addition, each small sample area has a swivel handle for quicker and easier sample picking and loading.

These are the simple internal layout of the tianchi cryogenic liquid nitrogen freezer. The samples are stored separately in liquid nitrogen, allowing a greater number of samples to be stored, and when used with the automatic replenishment system, the stability and safety of the samples is guaranteed.
