Ultra-low temperature freezers are often used to store medicine, vaccines, hormones, stem cells, semen, biochemical reagents, etc. The correct refrigeration method can greatly improve the refrigeration effect of items and the use effect of the ultra-low temperature freezer, and prolong its service life. The following are some tips for refrigerating items in the ultra-low temperature freezer.

Tips for refrigerating items in ultra-low temperature refrigerator:

1. If the items to be stored have high water content, they must be cooled in advance before storage.

2. For items with large capacity and high water content, they need to be pre-cooled in quick-freezing equipment before storage to avoid long-term non-stop of the refrigeration system.

3. Before storing items for the first time or storing items again without using the ultra-low temperature refrigerator for a long time, first run the refrigerator empty to enter a stable running state for about 12 hours, and wait until the refrigerator is fully cooled before putting the items in.

4. Do not put too many items at one time, and the items stored inside should not be too crowded. Some room must be left to ensure the circulation of air in the refrigerator.

5. When storing items packed in plastic bags, be careful not to scratch the plastic bags near the metal edge.

6. If storing a lot of items in first use, gradually lower the temperature setting, and keep it for 7-10 hours after each drop of 10°C until the set temperature is reached.

Medical refrigerators are widely used in scientific research institutions, medical and health care, biopharmaceuticals, pharmacies and many other industries and fields, which are one of the essential medical equipment.
