The one thing I learned from Brazing Cathode (oh did I title this solve with wrong word) I is that radius 2 hex arm is pretty powerful in purification, and it is here. All inputs and purifijection in one chamber for 9 instructions (plus optional 1 for salting), imagine that.

I'm not as happy with the other chambers, but I do feel I've looked at all 6 possible anime placements.
