Ultra-low temperature freezer security guide in operation and maintenance
Ultra-low temperature freezer is also called the ultra-low temperature freezer, cryopreservation box. Press can be roughly divided into: the preservation of the applicable tuna, electronics, special materials of low temperature plasma, biological materials, test and save the vaccine, reagent, biological products, chemical reagent, species, and biological samples kept at low temperature.
Maintenance and maintenance of cryogenic refrigerator is particularly important to extend the life and the normal use, if not accurate temperature control the saved objects often lead to damage to cause great influence to the experimental results, thus affect the normal work.
Clean once a month to ensure its cleanliness
With dry cloth to remove the fridge a small amount of dust on the internal and external and accessories, if the fridge is too dirty to use neutral detergent, wash thoroughly with clean water after washed
Wash. But not inside the refrigerator and the upper water, otherwise it will damage the insulation and cause failure. The compressor and other mechanical parts do not need to use the lubricating oil. Clean the fan at the back of the compressor must be careful. Clean after the completion of security checks to ensure good refrigerator plug, not virtual meet; Ensure that the plug is no abnormal heat; Ensure that the back of the refrigerator distribution of power cables and wires no cracks and nicks
The importance of cryogenic refrigerator maintenance
The cryopreservation of the sample in the modern biology research is extremely important
Normal operation of cryogenic refrigerator = samples safe and reliable
1, must understand the impact of environment on the refrigerator
2, familiar with basic operation, maintenance and maintenance knowledge
3, develop good habits
Let the free circulation of air around refrigerator
• refrigerator around vacant for at least 15 cm of space, with 30 cm at the top of the space
, at the top of the refrigerator can not store things, lest affect at the top of the radiator
The refrigerator a reliable environment
As far as possible let refrigerator surroundings temperature between 15-32 oc for a long time
Full account of the differences of the energy consumption of the winter and summer, reasonable control the environment temperature
, the environment temperature is too high, for a long time can damage the compressor life
• refrigerator heat dissipation and would result in higher temperature
To eliminate the influence factors of affect the refrigerator heat exchange:
• don't put the refrigerator placed on the edge of the heat source
• don't put the refrigerator placed in vent
The reserved refrigerator dedicated line
Basic operation
After boot: plug in the power supply plug, pressing the button back the lower right corner, "O" in the representative pass, "I" in the representative
If the equipment when handling more than 45 ° inclined, the equipment before the start vertically after 24 hours to boot!!!!!!!!!!!
Open, open the battery switch: positive below white door, down the switch according to "I"
Battery function: when power outages, can provide power to the display panel, provide sound and light alarm
, the new machine use: refrigerator running to boot set to 60 degrees, after reaching temperature 2 hours, set set
- 80 degrees, when after reaching 80 degrees, to keep the refrigerator no-load running 12 hours and then began to put the samples
Samples, the refrigerator storage method recommended: first of all to put the need in cryogenic refrigerator samples on frozen - 20 degrees freezer. Pre frozen after the first sample is placed within the top layer partition, shut the door; Waiting for display temperature back to set data, then place your samples on the need to position.
Samples, vertical cryogenic refrigerator storage methods: above 2 layer often need to open the door and out into the sample, the bottom layer placed long-term storage is less used in the sample
