Vapor-phase liquid nitrogen storage container, the intelligent product of the liquid nitrogen tank industry! It integrates sample storage, automatic rehydration and intelligent management, which is convenient for users, especially for laboratory and scientific research users. Today KGSQ will discuss its advantages and disadvantages.
One of the obvious advantages: large capacity and large diameter
With a large volume of more than 350 liters and a large diameter of more than 324mm, some containers are equipped with ladders, which are convenient for sampling and storage.
Advantage 2: Vapor-phase liquid nitrogen storage mode
What is even more commendable is its vapor-phase mode, that is, independent liquid nitrogen and sample storage areas. They do not “meet” each other, and samples do not need to be soaked in liquid nitrogen. Burst and cross-contamination are perfectly avoided by the vapor-phase liquid nitrogen storage container.
The third advantage: automatic rehydration
Vapor-phase liquid nitrogen storage still needs to consume liquid nitrogen, and liquid nitrogen must also be replenished. But its replenishment is very simple, automatically controlled by computer, it only needs to pre-configure the liquid nitrogen supply tank and set the liquid replenishment height.
Advantage Four: Intelligent Management
The intelligent management of vapor-phase liquid nitrogen storage containers is very comprehensive, in addition to automatic liquid replenishment, there are also data records, temperature alarms, etc.
But everything has two sides, and absolutely perfect things rarely exist. Of course, vapor-phase liquid nitrogen storage containers also have their own disadvantages.
Disadvantage 1 must be bulk biological sample storage
This limits the scope, and non-batch stem cells, vaccines, strains or sperm banks cannot use gas-phase liquid nitrogen storage containers.
Disadvantage 2 The storage temperature is higher than that of liquid nitrogen itself
Vapor phase storage, that is, use vaporized liquid nitrogen to cool down.
Liquid nitrogen gasifies when it is heated. Therefore, the temperature of gasified nitrogen is higher than that of liquid nitrogen, and the storage temperature is higher than that of immersion in liquid nitrogen.
Disadvantage 3 High capital investment
A disadvantage that is not a disadvantage!
The vapor-phase liquid nitrogen storage container has a capacity of 350-1800 liters, a huge sample storage space of hundreds of thousands or hundreds of thousands, and the intelligent functions required for sample management, which correspond to relatively high capital investment. The establishment of a non-biological sample bank or the storage of a large number of samples can easily exceed the original budget.
The above are the advantages and disadvantages of vapor-phase liquid nitrogen storage containers, and whether they are used or not needs to be determined according to their own needs!
