What is inside a 25 Liter LN2 Dewar

Описание к видео What is inside a 25 Liter LN2 Dewar

I bought this dewar off ebay several years ago and it never quite worked correctly. Sure it held LN2 but leaked pretty bad. I suspect at some point the dewar got over pressurized due to the withdrawal device and popped the safety vent to prevent it from exploding. So what better way to spend an evening than cutting apart a $1000 USD dewar with a sawzall
