I would clean and reuse them. Why would you autoclave them?

Re: Man made?

Hi 75RR,
It could be the remains of an insect's compound eye. On the lower right corner of the object I imagine I can see lenses bulging from the holes.

Re: How to remove Reichert microtome chuck?

Hi Tom, I would remove the screw near the end of the ram, there may be another screw under the one you can see. Also I would completely loosen all the screws on the collar to see if that makes a difference. Needless to say I have no experience with this breed of microtome so I am only guessing. Peter.

Hi 75RR, Many years ago I was told, by a Zeiss agent who had visited the Zeiss factory, that the Zeiss workers make their own screwdrivers using sword steel for the blades. That being the case I doubt you will find a commercial equivalent. Best find some tough steel and start making your own. Hope t...

This looks like a mite to me, i can count seven legs in yourm photo ( mites have eight legs).
What do you mean by "bug"?; to an entomologist a bug is an insect with piercing sucking mouthparts, there many insects (and other invertebrates which are not bugs).
