1. Under low temperature conditions, avoid the deterioration and failure of some drugs, biological preparations, enzyme vaccines, etc. due to the influence of the external environment. Low temperature can slow down the denaturation or degradation of active ingredients.

2. For living organisms, low temperature conditions can slow down cell division and metabolic activities, maintain a good original state for a long period of time, and greatly improve the survival rate.

Laboratory cryogenic storage equipment

Classification of cryogenic storage devices

(1) Medicine refrigerated cabinet / medicine refrigerator

(2) Blood cooler

(3) Low temperature refrigerator/ultra low temperature refrigerator

(4) Liquid nitrogen tank

Medicine Cooler / Medicine Refrigerator

Several factors are critical to ensuring the quality of drugs, samples, and reagents, namely storage temperature, expiration date, UV exposure, and humidity.

The most important of these is the storage temperature. Usually, the storage temperature of medicines we see includes room temperature, shade and cool, and those that require refrigeration. The specific temperatures required by these conditions are:

Normal temperature: 10℃~30℃

Cool storage temperature: no more than 20℃

Refrigeration temperature: 2℃~10℃

If the temperature requirement is not specified, it generally refers to normal temperature.

Relative humidity should be maintained between 35% and 75%.
