For the cryogenic storage of experimental samples, conventional containers are used for routine quantities, that is, YDS series liquid nitrogen tanks, or upgraded small gas-liquid-phase liquid nitrogen tanks. Unconventional quantities, such as more than 10,000 cells, vaccines, plants and other biological samples can not be stored in conventional containers, need to be able to realize the batch storage and management of gas-liquid nitrogen tanks, also known as stem cell tanks, belong to the YDD series of liquid nitrogen biological containers!

Comparing with YDS series liquid nitrogen tank, gas phase stem cell tank has the following characteristics:

One, capacity, especially large capacity

Conventional liquid nitrogen tanks have a capacity of no more than 175 liters, or a little more than 175 liters;

Vapor phase liquid nitrogen tank is very different, 350 liters is only its small size, the larger is 1800 liters;

Capacity corresponds to the storage capacity, the conventional liquid nitrogen tank storage of biological samples up to 6000 or so, the gas phase liquid nitrogen tank storage capacity of ten thousand for the calculation.

Two, modes, dual mode support

Conventional liquid nitrogen tanks have only one mode, i.e. pure liquid phase, where samples are immersed in liquid nitrogen;

Gas-phase liquid nitrogen tanks support gas-phase and liquid-phase modes, which can be stored in liquid nitrogen, but also can be stored in sample liquid nitrogen separation. However, the comprehensive capital investment, sample safety and management convenience, almost always choose the gas phase mode to store liters.

Three, management, a smarter way

Take the replenishment of liquid, conventional liquid nitrogen tanks either looking for gas companies, or with the replenishment tool - liquid nitrogen pumps or self-pressurized liquid nitrogen tanks, and need to be manual.

Gas phase liquid nitrogen tanks, only need to be equipped with a good refill tank, you can realize fully automatic refill, and there is a liquid level alarm function, conventional liquid nitrogen tanks want to alarm need to be added to the liquid level detector/alarm.

In addition to automatic replenishment and liquid level alarm, the gas phase liquid nitrogen tank also supports remote alarm, temperature alarm, etc. Its intelligent monitoring and management system, which also records the sample data, can be de-misted with one key when the lid is opened; there is a hot gas bypass and excellent temperature maintenance for a long time after the lid is opened, which is very convenient for the users.

But note that if your sample quantity is not more than 6000, and there is no requirement that must be preserved in vapor phase, then conventional liquid nitrogen tank is more suitable for you. If the number of samples is particularly large and there is a need for sample bank establishment, the vapor phase stem cell tank is more suitable for you!
