[NHCOLL-L:4533] RE: freezers for coral specimens

[Moore, Simon]

On the subject of freezing corals, I would approach this with great
caution.  In theory it should be fine but I have seen too many colonies
(ouside) at English country houses that have been fissured by frost.
Octocorals too can sometimes become detached from their horny skeletons
through freezing.  I would be more tempted to unpack within a
sticky/greasy barrier and leave for a while to ensure total eviction and
freeze the wrappings.

You could freeze the bagged boxes right off without unpacking first,
then unpack and dispose of packing material afterwards. Then you
wouldn't have to worry about unwrapping potentially infested items in a
clean space.

On the subject of freezing pests... I have just received a donation of
modern coral skeletons (pre-CITES) and fossils previously stored in a
damp basement for years. We have spotted silverfish in the boxes, so I'm
wondering whether it's worth freezing the specimens (can they be
frozen?) after unpacking and disposing of the boxes/newspaper wrappings.
All the boxes are temporarily sealed in bags.   

 

Any advice? Thanks,

 

Tiffany

Generally speaking the -34 deg C should more than enough - I generally
recommend - 20 deg C with no defrost cycle..(based on Tom Strang's work
at CCI)   Also, go to the Museum Pests web site:
http://www.museumpests.net -- There should be a fact sheet are fact
sheets up on most of the museum pests, and there may be the results of a
survey recommending freezers that was done earlier this year posted.

Hi,

 

We are planning to purchase a new chest freezer for our herbarium. We
find that they are available in models that freeze to -34 deg. C or to
-40 deg. C. Does anybody know if the lower temperature is more effective
at killing cigarette beetles, or if we can get by with the less
expensive, -34 deg. C. freezer?

 

thanks!
