[Nhcoll-l] Vacuum for specimens

Fri Sep 3 05:42:23 EDT 2021

just as a quick reference and example from a German retailer specialised 
on art restoration (English website - if you scroll down, there is a 
huge variety of brushes, adapters and nozzles etc.):

here a example for the hand-help option Simon suggested (equipped with 
HEPA filters):

>> 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.

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?
