Ultra low temperature refrigerators are devices designed for storing and protecting biological samples, and are widely used in medical research, life sciences, pharmaceuticals, hospitals, biological products and laboratory research. Then, how often do ultra-low temperature refrigerators need to be cleaned?

It is better to clean the ultra-low temperature freezer once a month to ensure its cleanliness:

1. Use a dry cloth to remove a small amount of dust on the inside and outside of the refrigerator and accessories. If the refrigerator is too dirty, use a neutral detergent and rinse it thoroughly with pure water after cleaning. However, do not flush water inside and on the top of the refrigerator, otherwise it will damage the insulation material and cause malfunctions.

2. The compressor and other mechanical parts do not require lubricating oil. Be careful when cleaning the fan behind the compressor.

3. After cleaning, perform a safety check to ensure that the refrigerator plug is properly plugged in and not loosely connected, and ensure that the plug is not abnormally hot and that the power cord and distribution wires on the back of the refrigerator are not broken or scratched.

The maintenance and care of medical ultra-low temperature refrigerators are particularly important for extending their service life and normal use. If the temperature control is inaccurate, it often causes damage to the stored objects, which has a great impact on the experimental results.
