I don't imagine this is telling Brian anything new, but for the rest of us ... It
costs US $52 a litre. It's used for histology. It's alcohol-based. "NEO-FIX®
can be used for the accelerated fixing of cryo-sections conventionally
processed by microwave." Merck don't reveal the formula.
Putting that together my guess is that this is a specialised fixative for use in
exacting conditions such as medical pathology (tissue biopsies) where
large numbers of slide sections are microwaved to improve fixative
penetration. Hot formaldehyde fumes would not be very nice stuff to work
with, hence maybe Neo-Fix.
