How to check the sealing of gaskets in Chest Deep Low Laboratory Refrigerators
Low-temperature refrigerators rely on gaskets to maintain the seal on the door. This will allow cold air to enter and hot air to enter the outside world. The gasket seals of Chest Deep Low Laboratory Refrigerators do not work properly, which may seriously affect the efficiency of the refrigerator.
1. Feel the cold air
Touch the closed door with your hand to prevent air-conditioning from escaping. If you feel cold air, the gasket is not sealed. This is most likely the result of dust accumulation, which is easy to clean. When performing this operation, also check for cracks around the gasket. If cold air escapes due to a cracked gasket, it needs to be replaced.
2. Use a flashlight
Take a flashlight and turn it on. Put the flashlight in the low-temperature freezer and close the door. Check if any light passes through the closed door. This indicates that the gasket is not sealed, which reduces the efficiency of the equipment.
3. Use paper money
Take a banknote and close it on the door of the low-temperature freezer. Make sure that there are enough bills sticking out to pull them out. If the bill slips out easily, there is a weak spot in the gasket seal. The entire seal should be checked, especially at the corners of the equipment.
4. Check the seal

Check the sealing ring carefully to see if there is any looseness, cracks, tears or dirt. Any dirt or dust should be removed immediately to reduce the chance of obstructing the seal. If necessary, check and clean the surface of the low-temperature refrigerator in contact with the gasket.
