Suitable for freezing of ice bars and storage of various things needing refrigerated storage such as blood plasma, reagent, etc. Suitable for use in hospitals, clinics, health and disease prevention systems, blood banks, laboratories in colleges & universities, the frozen food industry and catering industry, etc.The maintenance and maintenance of ultra-low temperature refrigerators is particularly important for prolonging its life and normal use. If the temperature is not accurately controlled, it will often cause damage to the preserved objects, which will have a great impact on the results of the experiment, thereby affecting the normal progress of the research work. Clean it once a month to ensure its cleanliness. 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 thoroughly with pure water after cleaning. But do not flush the inside and the upper part of the refrigerator, otherwise it will damage the insulation material and cause malfunction. The compressor and other mechanical parts do not need to use lubricating oil. Be careful when cleaning the electric fan at the rear of the compressor. After cleaning, perform a safety inspection to ensure that the refrigerator plug is plugged in properly and not falsely connected; ensure that the plug is not abnormally hot; ensure that the power cord and distribution cord on the back of the refrigerator are not broken or nicked
