Ultra-low temperature freezers have adjustable temperature and good uniformity, and are suitable for laboratories, scientific research, pharmaceuticals, disease prevention and control centers, pharmaceutical companies, biotechnology companies, chemical companies, universities, food laboratories, other laboratories, etc. So, what factors should be considered in purchase?

Ultra-low temperature refrigerator selection factors:

1. The cooling process rate should be as fast as possible to avoid low temperature damage during the cooling process. The water in the cells forms ice crystals, which then punctures or bursts the cell membrane, causing serious damage to the cells.

2. During the freezing period, the ultra-low temperature refrigerator should be able to operate continuously and stably and remain relatively stable.

3. The samples to be stored have a certain temperature sensitivity and have different requirements for temperature fluctuations, that is, the ultra-low temperature refrigerator needs to be analyzed for temperature uniformity.

4. The impact of opening and closing the door to take and put samples should also be analyzed, and the temperature data of the whole process needs to be recorded.

5. Behind the numbers of temperature uniformity, it requires to check detection method.

Medical refrigerator is a freezer used to store medicines, samples, reagents, biological products, vaccines, and blood products. Medical refrigerators have more precise temperature control and a wider temperature adjustment range.
