-86℃ Ultra Low Temperature Freezer: The Ultimate FAQ Guide

What is -86 ℃ ultra low temperature freezer?

The temperature range of the ultra-low temperature freezer is between -50 and -86 ℃. They are used to store drugs, tissue samples, enzymes and other biological materials.

Ultra low temperature freezer has become an indispensable tool in clinical environment. Laboratory technicians in many fields regard them as an important part of their work and research.

 

What is the working principle of the -86 ℃ ultra low temperature freezer?

Refrigeration principle of ultra low temperature freezer: generally, two-stage refrigeration is adopted. The temperature sensing probe of the equipment is a thermistor. Different temperatures are displayed on the panel according to the resistance value (i.e. the temperature). When the power is turned on, when the panel shows that the temperature is higher than the set temperature, the first stage compressor starts first, and the first stage refrigeration system starts to work, so that the condenser temperature of the second stage refrigeration system drops, that is, the refrigerant temperature of the second stage drops. After a few minutes’ delay, the second stage refrigeration system also starts to work, and its evaporator is on the inner wall of the refrigerator, which can greatly reduce the internal temperature of the refrigerator, All the heat released by its condenser is absorbed by the evaporator of the first stage refrigeration system, and the heat released by the first stage condenser is scattered in the air. When the internal temperature of the ultra-low temperature refrigerator reaches the set temperature, the resistance of the temperature sensing probe transmits the information, the control relay is powered off, and the two-stage refrigeration system stops working. When the temperature in the refrigerator rises again and exceeds the set temperature, the refrigerator repeats the above operation process again, so that the temperature in the refrigerator is always maintained at the set temperature.

 

What are the uses of the -86 ℃ ultra low temperature freezer?

It is used to preserve viruses, bacteria, red blood cells, white blood cells, skin, bones, bacteria, biological products, ocean products, electronic devices, special materials, etc

It is applicable to blood stations, hospitals, centers for Disease Control and prevention, scientific research institutes, laboratories of electronic and chemical enterprises, biomedical engineering research institutes, and ocean fishing companies.

 

What is the difference between -86 ℃ ultra low temperature freezer and ordinary freezer?

1. Temperature difference

The minimum temperature of ordinary refrigerators is -18℃

The common ultra low temperature freezer are generally divided into -25℃, -40℃, -86℃, -130℃, and -160℃. The ultral low temperature refrigerators produced by various manufacturers will also be different in temperature division.

 

2. Different uses

Ordinary refrigerators are mainly used for household use to store food, etc.

The ultra low temperature freezer is mainly used for scientific research, preservation of medical supplies, low-temperature experiment and storage of biological products, ocean products, electronic components, chemical materials and other special materials.

 

3. Different refrigeration principles

There are two kinds of ordinary refrigerators: gas absorption type and semiconductor type.

The refrigeration system of ultra low temperature freezer adopts the working principle of the new generation single compressor self cascade refrigeration technology. Generally, two compressors are used as high and low temperature compressors.

 

What is the importance of ultra low temperature freezer?

1. Sample safety

The design of ultra low temperature freezer is based on sample safety. Most ultra low temperature freezers on the market have a series of safety functions. When laboratory equipment fails, specimens worth thousands of dollars may be destroyed. The ultra low temperature freezer can provide temperature stability in the internal chamber, so as to retain the samples.

 

2. Energy Efficiency

Modern ultra low temperature freezer not only have good functions, but also save energy. The energy consumption of most ultra low temperature freezer is about 25% lower than that of standard laboratory equipment, which can save laboratory costs. In addition, the ultra low temperature freezer has low noise.

 

3. More Size Options

Regardless of your storage needs, there are many sizes of ultra low temperature freezer to choose from. Vertical ultra low temperature freezers are recommended for laboratories with a large number of samples and frequently used.

Chest freezer is suitable for laboratories that do not need to take out samples frequently for long-term storage.

 

How to maintain the ultra low temperature freezer

Due to the scarcity of refrigerant, high price and complex equipment structure, the maintenance cost of ultra-low temperature refrigerator equipment is high.

The damage of ultra low temperature freezer is mostly caused by improper use and maintenance. In order to ensure the normal operation of the ultra low temperature freezer, please pay attention to the following points:

1. Ensure the ambient temperature. The working environment temperature of the ultra-low temperature refrigerator must be below 30 ° C and the surrounding ventilation must be good. High temperature or poor ventilation can easily cause equipment damage.

2. Clean the cooling filter screen regularly (once every two months). If the filter screen is not cleaned for a long time, the dust blocks the mesh, resulting in poor heat dissipation, resulting in damage to the heat dissipation motor and then the compressor. Please refer to the instruction manual for cleaning methods.

3. Regularly clean the ice at the door seal of the refrigerator. If it is not cleaned for a long time, the insulation effect will be seriously reduced, which is easy to cause damage to the compressor due to long-term overload operation.
