[Nhcoll-l] Experience with (which concentration of) DMDM Hydantoin for fixation?

[SIMON MOORE]

Hi Sidsel,
This sounds like a good idea.  I am unfortunately inexperienced in the use of Dekafald as a fixative but the Steedman PFP is excellent if used in conjunction with the Steedman fixative which containes formalin but a reduced amount than the straight fixative 10% formalin solution.  However please bear in mind that the Steedman solutions were primarily devised for use with zooplankton as opposed to larger and more proteinaceous specimens.
Hopefully some others with experience of Dekafakd can advise further.
 
All the best, Simon (Moore)

Dear all,

For preparing specimens (amphibians and like) for the school service at the museum I work at, I need to use DMDM Hydantoin as a fixative instead of Formaldehyde as one usually does. This is due to health regulations (the children are to touch the specimens).. Does any of you have experience with using DMDM Hydantoin? - what concentration to make? Afterwards the specimens will be preserved in Steedmans PFP solution..


Best regards,

Sidsel Willemann
