Tips for Using Ultra-low Temperature Refrigerator

Tips for Using -80℃ Ultra-low Temperature Refrigerator

Low-temperature refrigerators are also called ultra-low temperature storage boxes, ultra-low temperature refrigerators and freezers, which are suitable for scientific research institutions, ultra-low temperature experiments of special materials, electronics industry, chemical industry, university experiments, biological engineering, ocean fishing, etc. It can be used to preserve viruses, germs, red blood cells, white blood cells, skin, bones, bacteria, semen, biological products, ocean products, and low temperature tests of electronic devices.

When using -80℃ ultra-low temperature refrigerators, some aspects must be paid more attention to avoid some unknown failures during the operation.

I. Placement environment

We must pay attention to the placement environment of -80℃ ultra-low temperature refrigerators. Generally speaking, -80℃ ultra-low temperature refrigerators should be placed at an indoor temperature of 5-30 ℃. The indoor humidity should also be noted. The ambient temperature should not exceed 30 degrees Celsius. Ensure normal heat dissipation, keep the room ventilated and maintain a good heat dissipation environment.

II. Sample access

When storing samples in -80℃ ultra-low temperature refrigerators, be careful not to put some strong acid and corrosive samples into the refrigerator, so as not to corrode the refrigerator. In addition, when opening or closing the door of the refrigerator, be careful not to open too much and try to shorten the time. Place the frequently accessed samples on the top. If they are not used for a long time, place the bottom to avoid certain loss when opening the door. In addition, once the refrigerator door is locked, do not open the door forcefully so as not to damage the door.

III. Filter cleaning

The filter of -80℃ ultra-low temperature refrigerators should be cleaned every month, and the dust on the condenser should be cleaned frequently. In the event of a power outage or other failures, you must turn off the power switch, check again where the fault is, and turn on the power when it is resolved.

During use, only correct operation and attention to maintenance can ensure the normal use of the ultra-low temperature refrigerator and effectively extend its service life.
