2.    Methanol is a little faster than ethanol, is generally cheaper but is more toxic.

3.    Isopropyl alcohol is a slower dehydrating agent but is miscible with paraffin wax to a limited extent.

Dear Histonetters, We currently use a denatured, lab grade alcohol which consists of 95 parts ethyl and 5 parts isopropyl.  We are considering a switch to a mixture of 90 parts ethyl, 5 parts isopropyl and 5 parts methyl.  We will be using this reagent alcohol on our processor and stainer.  We are considering the switch for a simple reason:  easy pour bottles!  Would there be a noticeable difference in processing/staining due to the different makeup?  What is everyone else using? thanks, Beth PooleHSRL-A GLP Compliant Laboratory137 S.
