The short answer is - Choose the cheapest
anhydrous alcohol. Isopropanol is cheaper than
ethyl alcohol if you have to pay booze-based
taxes when you buy ethanol. If your lab can get
duty-free ethanol it may be cheaper than
Poisoned or denatured alcohol (ethyl mixed with methyl
or propyl) is usually cheap but it may contain up to
5% water. It can be used as to make 70%, and 95% but
not "absolute" (water-free) alcohol.
What are "the blends designed for use in histology"
that you ask about? There's no magic in the business
