A previous unit, a dismal failure. Should have first tested
copper against sodium hydroxide--the chemical reaction resulted in what looked like old fiberglass

water through, for cooling.
Cutting slots in
the teflon rod that held the plate edges to the correct spacing.

became of this unit.
More proof that
"dangerous" is no joke.
What lab is
complete without a rat?
