LN2 storage: flasks
 

bad idea LOL

i have 5 flasks...

since my 25L dewar had like 15Liters and i needed to refill for 3d03 bench...i had to somehow stash some ln2 somewhere...so i used the 5flasks

@ 7am 5 full flasks

@7pm 40% remain.....


total ln2 at the moment : 25L + 10L + 40%(5) = 37L

Yes flasks are no good (only advantage on them is that Airgas won't charge for refilling the small flasks when you go there to get the big one full). So I always fill 2 flasks and use them to pre-freeze the pot without going to my dewar...
