[Nhcoll-l] Vacuum for specimens

Fri Sep 3 05:25:16 EDT 2021

To add to Dirk’s message, I recommend a HEPA filtered vacuum that has a variable speed drive or can be used with a rheostat, and accepts micro vacuuming tools. This will provide safety for people and other collections, allow you to adjust the suction level, and permit work on sensitive areas of specimens and objects.

... adding to Simon: might be worth knowing the conservation history of the skins, especially in the case of historic specimens that might be contaminated with arsenic and similar; filters in most vacuum clears are not equipped to hold such sort of contaminants back, and the exhausted air would disperse the contaminants in the storage area. Some vacuum cleaners allow connecting of pipes on the exhaust outlet, which would allow to divert this air for example into a fume hood or similar devices that are equipped with the required filters.

Might be worth considering ...

Hi Tonya,

You’ll get a lot of answers for this I expect.  Don’t forget the vacs that you can wear like a back-pack, if you’re up a ladder and ensure you have a variable speed knob/adjuster, there is quite a range under the varying titles of Museum or Conservation vacuum cleaners.

With all good wishes, Simon

Hello all,

I thought that this had been a NHCOLL discussion before, but I can’t seem to find the info I am looking for, even in the archives (so apologies for redundancy).

I would like to purchase a vacuum for cleaning study skins and trays. I know it should have adjustable suction, and maybe need some sort of custom built stand for it to sit on, with casters and a prop to hold up the hose (so it doesn’t get in the way or accidentally knock specimens). To use it I would get some brush and small area attachments, and of course use textile cloth as a filter or something like that when appropriate. Is there anything else I should be thinking of, or any specific vacuums that are great for this purpose?

Thanks in advance for your thoughts!

Cheers,

Tonya
