1, the important thing is the control of the refrigerator temperature, the temperature inside the refrigerator needs to be between 5-30 degrees, the refrigeration temperature is generally -80 degrees, in the operation of the time to consider its time-consuming overall situation.
2, 80 degrees inside the ultra-low temperature refrigerator try not to put some strong corrosion and strong acid substances, so as to avoid corrosion site. Note that often to access the sample please put on the upper two layers, the need for long-term preservation of infrequent access to the sample please put on the lower two layers, so as to ensure that when the door is opened, the cold air is not excessive loss, the temperature will not rise too quickly.
2, to ensure that the 80 degrees ultra-low temperature refrigerator power supply voltage, once the power outage, close the refrigerator power switch and battery switch in a timely manner, and wait for the solution of no problem to open the switch.
4, 80 degrees ultra-low temperature refrigerator environment, remember to maintain good ventilation and heat dissipation, around the ambient temperature can not exceed 30 degrees, keep the environment clean and dry.
Extended information
80 degrees ultra-low temperature refrigerator is a lower temperature than the low temperature, 80 degrees ultra-low temperature refrigerator is the use of low-temperature refrigerator production and manufacture of a refrigeration equipment. Generally speaking 80 degrees ultra-low temperature refrigerator can also be ultra-low temperature preservation box, ultra-low temperature freezer and other refrigeration equipment. It uses a single compressor self-compounding technology, relatively simple structure, low energy consumption, low failure rate, the use of non-fluorine environmentally friendly mixed refrigerants.
Ultra-low temperature involved in the field is not as much as low temperature involved in the field, but ultra-low temperature involved in the field is generally used in scientific research institutes or laboratories to do low-temperature experiments and other aspects of the 80-degree ultra-low-temperature refrigerator can be preserved biological products, chemical reagents, plasma, vaccines, strains and biological samples and so on.
