What diameter liquid nitrogen tank should I choose for liquid nitrogen cell storage?

Liquid nitrogen tanks that can be used for sample storage are designed in various models based on the number of samples;

The key to distinguishing them is caliber. The same capacity has different calibers, and the same caliber also has different capacities.

When it comes to the actual selection, after determining the capacity, you must also choose the caliber!

Because, if the diameter is too small, it will be inconvenient to take the cells; if the diameter is too large, the price will be high, and the loss of liquid nitrogen will also be higher!

So what diameter liquid nitrogen tank is suitable for liquid nitrogen cell storage?

First look at the number of cells to determine the approximate capacity range, and then choose the caliber!

If the number of cells is only a few or a dozen, a small portable liquid nitrogen tank can be used, such as 10 liters or 6 liters. In terms of diameter, choose the smallest diameter, 50mm. Because the number of cells is small, whether they are directly wrapped and placed in the container, It is better to use the liquid nitrogen container with its own bucket for storage, and it will not be inconvenient due to the small diameter.

If the number of cells is less than 600 or more than 100, the capacity range can be set at 15-30 liters, such as 15 liters, 20 liters and 30 liters. The caliber selection depends on the specific number of cells and whether a cryopreservation rack is required. It is optional without a rack. 50mm, 80mm. If you want the convenience of liquid nitrogen cell storage and easy access, use a larger diameter. If you want to equip a shelf, you must have a liquid nitrogen tank with a diameter of 125mm or above.

But if the liquid nitrogen cell storage capacity is in the range of 600-6600 cells, the optional capacity is 30-175 liters, and the diameter is 125mm-216mm. This type of cell storage liquid nitrogen tank comes standard with 6 freezing racks, which is suitable for laboratories and scientific research. Made for users, it has large internal storage space, small evaporation loss of liquid nitrogen, and long static storage time. In addition, if you want to store more than 10,000 cells, it is better to use an open-top liquid nitrogen tank than a gas-phase liquid nitrogen freezer with a capacity of more than 350 liters and a large diameter of more than 326mm.

The above are the suggestions on what diameter liquid nitrogen tank to choose for liquid nitrogen cell storage. The specific quantity is appropriate!
