General classification of cryovials and precautions during purchase

Cryovials is also called freezing tube, which is mainly used for low-temperature transportation and storage of biological materials.

Cryovials are generally used for cryopreservation of laboratory cells. It is often used in biological and medical experiments, but it is also used in experiments in other industries such as food.

There is no strict division for the classification of cryopreservation tubes. Generally, they are divided according to the capacity according to the experimental needs, such as 0.5ml, 1.0ml, 1.5ml, 1.8ml,

2.0ml, 4ml, 5ml, 7ml, 10ml, etc. can also be classified according to special purposes. General freezing tubes cannot be put into liquid nitrogen, and only those treated with special materials can be put in. At the same time, there are double-layer and non double-layer frozen storage tubes with and without silica gel pads, as well as colorless, variegated and various pure colors. These are designed by each manufacturer according to the needs of the experiment or the convenience of the experiment, and there is no strict division.

When purchasing, you should see whether the purchasedCryovials is suitable according to your own needs. Generally, the Cryovials cannot enter the liquid nitrogen. If you need to enter the liquid nitrogen for storage, you should choose a sealed low-temperature resistant special Cryovials. You should also know whether the purchased Cryovials is sterile. If the experimental requirements are high, you should buy sterile and DNA free and RNA free cryopreservation tubes. In addition, if it is newly purchased and not opened outside, it can be used directly. If it is opened outside, it can be pressurized.

At present, there are many kinds of Cryovials in the market. The specifications and materials of Cryovials produced by various manufacturers are different, and the price difference is also large. We need to purchase according to our own needs. Generally, high-grade biological materials with high requirements for experimental frozen storage can be selected. In case of low requirements, ordinary ones can be selected.
