タイトルまたは説明

As we all know, the storage modes of liquid nitrogen tanks can be divided into two types according to sample storage requirements: gas phase and liquid phase, that is, soaking in liquid nitrogen and storing in nitrogen. In order to make it easier for users to distinguish between the two, regardless of industry or brand, they are accustomed to using storage modes to identify them. Liquid phase storage is liquid phase liquid nitrogen tanks, and gas phase storage isgas phase liquid nitrogen tanks. This is also their main way of distinguishing themselves!
Of course, there are other differences besides this, lets introduce them one by one.
1. Model differences:
Including capacity size and national standard naming.
The liquid phase liquid nitrogen tank has a capacity range of ****5 liters and is named YDS. The national standard stipulates that the material is aluminum alloy.
The gas phase liquid nitrogen tank has a capacity range of *******0 liters and is named YDD. The material specified by the national standard is stainless steel.
For user use, just select the appropriate model and type based on the number of samples.
2. Mode differences:
Liquid phase liquid nitrogen tank, the sample is immersed in liquid nitrogen;
The gas phase liquid nitrogen tank meets both liquid phase and gas phase modes. There is a liquid nitrogen storage area at the bottom of the tank to provide liquid nitrogen to the sample area. Note: Vapor phase storage also requires supplementing liquid nitrogen.
3. Management differences:
Liquid-phase liquid nitrogen tanks have a wide range of uses and are relatively small in size. Sample classification management relies on buckets and freezing racks. There is no intelligent control and requires manual labor.
Regardless of the size of the gas-phase liquid nitrogen tank, it is equipped with an intelligent control system that can display the internal temperature, perform relevant alarms, and automatically replenish liquid nitrogen.
