[Nhcoll-l] Cleared and stained specimens

[Haff, Tonya (NCMI, Crace)]

Hello all,

Happy New Year! It's been very quiet here of late, so I am guessing many people are still enjoying their holidays?  For those of you back at work, I have a question regarding cleared and stained specimens.

We have about 20 or so small frog specimens that have been cleared and stained, and which to me look to be stored in glycerine. The glycerine in some of the jars looks like it may have been diluted (or else have absorbed some water), as it doesn't look as syrupy as it could.

These specimens need to be rehoused to new glass jars (they are currently in old plastic containers probably dating back to the 60s or 70s).  Some of them will require topping up. My first thoughts are to place them in their new jars in pure glycerine, but I would appreciate any thoughts or advice on this topic. I really don't want to create a new problem by trying to solve an old one!

Thanks so much!

Cheers,

Tonya
