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

[Sidsel Marie Willemann]

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,
