Re: DEWARs, SF6 and paper-caps



Re: LN2 storage
	Folk lore around here is that a styrofoam picnic jug
(not thermos) will hold 10 liters of liquid nitrogen all 
weekend.  If that is true, sure cheaper than a deward and a
lot less breakable.  This came off the vacuum web page
	http://www.tiac-dot-net/users/shansen/belljar/
I intend to give it a go when I get my vacuum systems back up
and running on the table which now has small TC.  So far, haven't
found a convenient local source of LN2, which is rumored to cost
of the order of a dollar a liter.
