[Histonet] Processing with mesh cassettes

We recently started using mesh cassettes for small biopsies, also called
micromesh, histoscreen or micro biopsy cassettes, depending on the
manufacturer. The techs, as well the pathologists, love them.
Unfortunately, it has caused reagent carryover in our tissue processors (VIP
3000 & Leica TP1050)after only one run.  The first reagent level
(formalin)decreases significantly; the 2nd reagent level(Prefer), as well
the next 3 alcohol levels, have significant increases. The tissue processor
used does not seem to make a difference. We run a 4 hour short program with
vacuum for biopsies. Has anyone else had this problem and if so, how did you
resolve it?  I really hate to stop using something the techs and
pathologists love and actually agree on!
