[Nhcoll-l] Freezing large specimens on formalin

[Esther Dondorp]

Dear Colleagues,


We have a large specimen tank (7*2*2 m) with specimens on formalin. For the
construction of our new museum building, we have to get rid of these
specimens temporarily until the new building with new specimen tanks is
ready. Because storage in alcohol or formalin somewhere outside the museum
will be a challenge, we were thinking of maybe storing these large
specimens frozen in a cold storage. And when the new building is ready
(somewhere in 2017), to thaw them and to change them gradually to alcohol.

I know freezing is not good for the specimens, but maybe it is different
when they have been sitting in formalin for soo long?

I would really appreciate hearing your thoughts on this.

Best wishes,


Esther Dondorp
