CAUTION

This cassette is almost definitely Not teflon
and Not acid resistant. Do Not place in a piranha bath.
This is a common cause of a serious lab accident.
Placing a large amount of oxidizable material
(like a poly propylene cassette) in a large bath of acid
(like a heated piranha or RCA bath)
results in violent reaction and likely significant acid splatter.
