[Nhcoll-l] Wet collection best practices - historical fluids

[Joachim Haendel]

Hello all,

there are some other fluids used for fixation and preservation.
(some of them are fairly dangerous):
 
Solution of Mercury dichloride (Corrosive sublimate) sometimes used for "vermes" and cnidaria,
also as part of  "Krygers preservation fluid" and "Pennaks fixative"

"Barbers solution" which contains ethanol, glacial acetic acid and benzene (!)

"Standfuss preservation fluid":  carbon disulfide, benzene and peppermint oil

and "Bouin solution" which contains also Picric acid (explosive !) in addition to formalin and lacial acetic acid.


Joachim
