Greg;
  That is essentially my point. In the same way that you never would try to enter the Monaco race with a small FIAT 600 (but with a Porsche) you should never try to do things with a household MW oven that will require a lab designed one.
  Things I did (for years) with my 2 MW ovens: dry slides, all sorts of boosts to special stains, heating the citrate buffer before the HIER procedure and things of that sort.
  Never to process tissue (although I had to confess some "indiscretionts in that realm").
  Regarding durability, my MW was used for more than 10 years continuously.
  Regarding reproducibility: it CAN be obtained as long as you calibrate it and know their capabilities [I even published a paper on that topic].
  Now to the original question about CAP regulations and household MW ovens: the answre and approach from their point of view is the same: "do NOT used them" [for that purpose].

  Oh Why Not,

I've taken the position (that from the CAP comment section of this question)
that use of a non commercial grade microwave is still safe and usable
provided you limit its use to heating of reagents such as PBS, agar, and
tris or citrate buffers.

Heating Bouin's is an issue, I would think.

Are any of the chemicals we heat in our microwaves toxic? I don't think most
special stains solutions fall in that catagory. That's the first question to
answer before getting to wrapped up in this ventilation issue?

but what about using a table top fume absorber with charcoal filters? CAP
writes these questions so ambiguously that it becomes a joke. This is the
main reason why I have a negative attitude towards CAP.
