BuoQua Liquid Nitrogen Container Aluminum Alloy Liquid Nitrogen Tank Cryogenic Container with 3 Canisters and Carry Bag, white

Charged the container with LN on 23 Dec and today, three weeks later, around 1cm LN is remaining. That's fair enough, considering that I am using it for transport purposes only. One issue I have faced multiple times is that the canisters get messed up very easily which makes putting the cover plug challenging experience. Rearranging the canisters results in loss of LN (cca. 1cm for 15 min).

Liquid Nitrogen Container - not the best airtight seal, so better for short term storage. This stuff evaporates at a rate of 0.39 litres per day
