[Histonet] micro chatter in prostate bx's

This might be stating the obvious but........
If this is a problem with one tech's cutting - does that one person
cut on the same microtome each time? If they do, then that may
indicate "mechanical" rather than personal error.
1.  If you are using tissue tek type embedding moulds and cassettes
check that the wax is filled up sufficiently in the cassette to
provide good stability.
2. Check that the microtome block clamp is holding the block tightly,
and that blades, knives etc are also without "play"
3. Depending on the age of the machine it might need a good service to
replace worn parts.
