ah yea , it's more than I wanted to spend..I take my 'projects' very seriously tho.The thinktank is already worth thousands of dollars and taken thousands of hours of my time.
The original 'thinktank'
is a fishtank, for all intents and purposes , however I'm about 98% sure if I fill it with -80c liquid , it'll shatter.That would be bad.
Borosilicate glass is the correct material for this application.Therfore , it's 500$ well spent.
