Has anyone heard of microscope grease? Some time ago I decided to regrease an old microscope that was seizing. I used an automotive grease. It allowed movement and the seizing went away, but the weight of the lens tube caused it to creep downward from gravity. If anything, it move too freely.
I asked the tech who services our microscopes what kind of grease he uses. He says he uses a "microscope grease". It seems that the grease allows free movement during focusing, but has enough tack to hold the tube in place so it won't move on its own. I believe that material property is called shear thinning. The tech also mentioned the grease costs $100 per ounce.
