[Histonet] Re: alternates to absolute ethanol

[Robert Richmond]

The commonly used (in medical histology anyway) alcohol is 90%
ethanol, 5% methanol, and 5% isopropanol. Since it's denatured, you
don't have the nuisance and taxes of handling beverage-quality
ethanol. The common name for this mix is "reagent alcohol". Other
denaturants such as methylisobutylketone (MIBK) (smells bad) and
acetone (removes eosin) should be avoided.
