Medical ultra-low temperature refrigerator is mainly used to store biological macromolecules, cells, tissues and organs, and are suitable for ultra-low temperature experiments in scientific research institutions and special materials, electronics industry, chemical industry, university experiments, biological engineering, marine fisheries, etc.

Laboratory medical refrigerator operating procedures:

1. The power supply voltage can be turned on after reaching the standard.

2. When starting for the first time, the sundries in lab refrigerator should be emptied, and then restarted. After the temperature reaches the preset temperature, put the samples in batches. Do not put all the samples in the refrigerator at once.

3. The refrigerator should be placed in an environment where the room temperature does not exceed 30 °C, avoid direct sunlight, and ensure good ventilation.

4. The medical freezer refrigerator should be placed on a flat and solid ground, and the compressor should be kept level. This is not only required for safety, but also makes the compressor work smoothly and reduces vibration and noise.

5. Clean the lab freezer regularly. Cleaning its inside and outside helps ensure the cleanliness, protects the ventilation and filtration system, and reduces the load on the compressor.

6. When the power supply voltage fluctuates greatly, such as repeated power outages, low temperature refrigerator should be temporarily stopped, and the power plug should be unplugged to prevent the compressor from burning. Do not start the compressor immediately after the refrigerator is turned off, stop for 2-5 minutes before starting.
