Laboratory liquid nitrogen machine adopts the institute of cryogenic mixing refrigerant throttling refrigeration technology, skid-mounted design, compact structure, able to continue, convenient supply of liquid nitrogen, can be used as a small amount of liquid nitrogen supply source in the region, by air compressor, cold and dry machine, filter, nitrogen host, buffer tank composition, nitrogen machine non-standard equipment, different brands of air compressor, cold and dry machine, tank and other prices are not the same. Too cheap supporting equipment will also affect the overall service life.
Supply small laboratory liquid nitrogen generator machine
The main components of the Small Liquid Nitrogen Generator are air compressor, air purification system, air buffer tank, nitrogen buffer tank, nitrogen generator, control cabinet, nitrogen analyzer, chiller, liquid nitrogen machine.
Liquid Nitrogen(ln2) has the characteristics of expansion, ultra-low temperature, odorless and non-toxic. Because of these characteristics, some items should be paid attention to when using Liquid Nitrogen(ln2) for airtight experiments.

Laboratory liquid nitrogen machine
- Why is there no liquid nitrogen machine in stock?
All pressure vessels have a service life, and the use of pressure vessels also needs to be registered. Off-the-shelf equipment indicates that it has been in production inventory for a period of time, which will affect the actual service life.
2, why your liquid nitrogen machine is more expensive than others?
The nitrogen making machine system is composed of air compressor, cold and dry machine, filter, nitrogen making machine and buffer tank. Nitrogen machine is non-standard equipment, different brands of air compressors, cold and dry machines, tanks, etc., are not the same price. Too cheap supporting equipment will also affect the overall service life.
A set of 500,000 equipment with 8 years and a set of 400,000 equipment with 5 years, is the most different.
- Why does the volume of liquid nitrogen machine affect the altitude?
The PSA nitrogen making machine uses the principle of pressure swing adsorption to separate nitrogen and oxygen in the air. The higher the altitude, the thinner the air, so less nitrogen is extracted from the air. So the nitrogen machine is related to altitude.
