I have found a source for liq N, now I need a dewar. What sizes should I be looking for? How much is enough capacity (Liters) is needed to do the job?
Then, once I get one, what is the procedure- do I tie some SS wire to the knife blade and lower it into the liq N, or suspend above it or is there some other way?
Thanks gentlemen-
