This container is only suitable for static storage of liquid nitrogen, not for transportation of liquid nitrogen. These liquid nitrogen containers have the characteristics of light weight, convenient carrying, long heat preservation time, etc. And are widely used in medical and scientific research departments. The holding time is tested in a static state without cans or samples. Moving the can, opening the can, or adding samples will speed up the evaporation of liquid nitrogen.
The actual holding time may vary due to the following factors. 1 If there is a jar in it. 2 The size, temperature and heat capacity of the sample. 3 The surrounding temperature and humidity.4 Any movement (during sample replacement or transportation). When using the liquid nitrogen dewar for the first time, fill up the LN2 and let it stand for about 24 hours. LN2 evaporates very quickly when it is first used.
After about 24 hours, refill the Dewar flask and place your sample in the Dewar flask. When filling a warm container with a low-temperature liquid or inserting an object into a liquid, boiling and splashing will always occur. Customers will need to obtain their own liquid nitrogen.
Static holding time (without canisters). Number of canisters for storage of samples. This item is in the category "Crafts\Other Crafts". The seller is "tianchidiwen" and is located in this country: CN.
