Natural Science Forum / Biology / Botany / May 2006

I use FAA (for 1 liter:  900ml 70% Ethanol; 50ml Glacial Acetic Acid; 50
ml Formalin).  I will either keep the flowers in the FAA or transfer to
70% ethanol after a few weeks.  As the solution evaporates, I always top
off with 95% ethanol.  The flower structure remains pretty well, but the
colors bleach quickly.  If anyone knows better solutions that are safe,
I would appreciate hearing about them.
