[NHCOLL-L:4594] Use of isopropyl for fixing and storing invertebrates

[Alexandra M Snyder]

Any ideas and/or caveats re: use of isopropyl for 
invertebrate preservation? See letter below.  Thank you in 
advance for information provided.  Lex

Lex,

I just exhausted my last supply of ethanol, so I'll be
fixing crayfishes and freshwater mollusks in iso and
storing as well (theoretically).  It is 99% ACS Iso and as
far as I can ascertain using Google, not denatured.  The
plan for now is to try and buffer (CaCO3) and add a little
glycerin as I do with denatured ethanol. My guess was
diluting to 50% isopropyl.
