Tips for saving liquid nitrogen commonly used in liquid nitrogen cryogenic boxes

　　1. Placement: The equipment should be placed in a cool and ventilated place, avoid direct sunlight, away from heat sources, and leave proper space on the top, left, and right sides and the back to facilitate heat dissipation. Because the high ambient temperature around the cryogenic box will increase the liquid nitrogen consumption of the test box.

　　2. Check the tightness of the cryogenic box sealing strip frequently. If the sealing strip is deformed, it will affect the tightness of the closure and cause the leakage of cold air, thereby increasing the consumption of liquid nitrogen. If the deformation is found to be serious, it should be repaired and replaced in time.

　　3. After using for a period of time, some frost will be produced. If the frost is not defrosted regularly, the cooling effect will be affected, and the consumption of liquid nitrogen will increase. Therefore, whenever you see the thickness of frost over 7cm, you should immediately defrost.

　　4. Whenever the door is opened, cold air will be exposed and hot air will invade. Therefore, when accessing samples, try to reduce the number of door openings and opening time, the door opening and closing action should be fast, and the door opening angle should be as small as possible.

5. Always pay attention to "bath" the liquid nitrogen cryogenic box. The surface of the equipment should be cleaned every two to three months. The more dust, the worse the heat dissipation effect, and the greater the liquid nitrogen consumption. Cut off the power when cleaning. Just wipe it clean with a damp cloth.
