FAQ:

What is an ultra-low temperature refrigerator?

Ultra-low temperature refrigerators are also called ultra-low temperature freezers, ultra-low temperature storage boxes, low-temperature freezers, low-temperature refrigerators, low-temperature storage boxes, and small low-temperature cold storages. It refers to a kind of refrigeration equipment whose temperature is adjustable and controllable and can be kept constant in a low temperature range; it is divided into vertical ultra-low temperature refrigerator and horizontal type, and the temperature range is roughly from -15°C to -190°C. It is a laboratory instrument such as biochemistry and molecular biology. It is mainly used for the preservation of reagents, biological samples or drugs. It has a wide range of applications, such as biological research, metal processing, hospital pharmaceutical companies, epidemic prevention systems, and military industries. .

How to use ultra-low temperature refrigerator:

1. With no items in the empty box, turn on the power and start the freezer in stages. The temperature of the freezer is firstly cooled to -20 degrees, then to -40 degrees after normal opening and stopping, and then to -60 degrees after 8 hours of normal opening and stopping. Observe that the freezer has Normal start and stop for more than 24 hours. Prove that the freezer performance is normal.

2. The freezer must be allowed to stand for at least 24 hours before it can be powered on.

3. Prohibition: All low-temperature storage boxes are storage devices. It is strictly forbidden to put too many relatively hot items at one time, which will cause the compressor to not stop for a long time, the temperature will not drop, and the compressor will be easily burned. The items must be put in batches, and the temperature is reduced in steps until the required low temperature!

4. After confirming that the freezer is normal, you can store items in the freezer. In principle, items with a temperature of -60 degrees should be stored, and no more than 1/3 of the cabinet's capacity. If the temperature of the stored items is higher than -60 degrees, the freezer temperature should be set at about 3 degrees higher than the temperature of the stored items (that is, if the temperature of the items is 20 degrees, set the low temperature cabinet temperature at 23 degrees) to ensure the freezer Shutdown, and normal start and stop for more than 8 hours.
