gloves

These days I do work requiring very clean parts to be used in ultra high vacuum environments.  In order to handle these parts without contaminating them with finger print oils or anything else, I use some form of rubber gloves.  I found latex gloves can be porus or dissolve in acetone, leaving residue all over everything I handle.  An old box of nitrile gloves from Allegiance I found in the lab served me well for some time.  When I finished that box I went down to the stockroom and picked up a box of microflex Midknight gloves (MK-296-L).  They looked cool because they're black and they felt good too.  However a large number of these gloves had some mysterious white poweder on them.  In the future I'll be sticking to Allegiance gloves if I can find them.
