New Liquid Nitrogen Dewar

One of the biggest set backs to using nitrogen is the rate it turns back into a gas. We have had a small 10 L dewar for the last couple of years. It was old and had cracks in the top. Every time we would fill it, it would evaporate back into a gas in less then 2 hours. With this new 25 L dewar with a built it thermal separator, the evaporation rate is very low because the nitrogen is under constant pressure. We can now fill this dewar and it will last the entire shift

Love the blog. Long time fan. Keep up the great work.

Can you tell me where you got the dewar? Been wanting to experiment a long time, but can't seem to find a dewar.
