Liquid nitrogen tank storage methods can be divided into two types: liquid phase and gas phase. Liquid phase storage involves directly immersing the sample in liquid nitrogen. Vapor phase storage uses nitrogen gas produced after the evaporation of liquid nitrogen to store samples.
In order to make it easier for users to distinguish, both the industry and the brand itself are accustomed to using models to differentiate. Liquid phase storage is liquid phase liquid nitrogen tanks, and gas phase storage is gas phase liquid nitrogen tanks.
This is one of their differences! It is also the main way to distinguish!
Today, let’s talk about their other differences!
1. Model differences:
Model differences include national standard naming and volume.
Liquid phase liquid nitrogen tank, made of aluminum alloy specified by the national standard, with a capacity of 1-175 liters, named YDS.
The gas phase liquid nitrogen tank is made of stainless steel specified by the national standard, with a capacity of 350-1800 liters, and is named YDD.
Select the appropriate model and type based on the number of samples.
2. Differences in modes
Liquid-phase liquid nitrogen tank, the sample is immersed in liquid nitrogen without any objection;
Gas-phase liquid nitrogen tank, can both liquid phase and Capable of gas phase, there is a liquid nitrogen storage area at the bottom of the tank to provide liquid nitrogen to the sample area. It does not mean that liquid nitrogen does not need to be added for gas phase storage.
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 or freezing racks, and there is no intelligent control that requires manual labor.
No matter how big or small the gas-phase liquid nitrogen tank is, it is equipped with an intelligent controller that can display the internal temperature, perform related alarms, and automatically replenish liquid nitrogen.
Liquid-phase liquid nitrogen tanks and gas-phase liquid nitrogen tanks are different in terms of model, storage mode, and management mode. When choosing a liquid nitrogen tank, you should choose the type that best suits you based on your specific needs.
