Hi ya'll!

Well, I just got through talking with someone at 3M...the FC-71 product has 
been discontinued. The highest boiling point heat transfer fluid they make is 
the FC-70 which boils at 215 º C. Just for grins I asked how much that stuff 
sells for, and was told that it's sold by the pound. A gallon weighs 15-lbs, 
and it's $60.00 a pound! YOWZA! $900 a gallon!!!

Called Galden Fluids, and they have a heat transfer fluid they call HT250 
which boils at 250º C. The say their stuff  
(http://www.inlandvacuum.com/galden.html) is a non ODP chemical. The spec 
sheet for all their stuff is at (http://www.inlandvacuum.com/galdenspecs.html)

A gallon of the HT250 is around $560...anybody ever use this stuff?

Still haven't found anything about the equipment. There's some used stuff out 
there but like Brian said in his post, I want to make sure I find something 
that I won't have to keep pouring this "liquid gold" into to be able run 
it...like the owl says; "I give a hoot, I don't wanna pollute!" (not 
mentioning the cost).
