  If you "long" protocol works well for you, reduce the time in each step in a way that at the end will be completed in the time you need, BUT preserving the time proportions you have now.

  Hello All,
I would like to get your suggestions for a processing schedule for
small biopsies (cores, GI's, other endoscopics). I want to process these
little guys separate from everything else to hopefully improve section
quality and perhaps staining quality. 

I don't want the absolute shortest possible schedule. We have a newer
VIP5 for our main processor (doing everything on one schedule currently)
and a much older VIP sitting idle as a backup that I plan to start using
for the biopsies. We process overnight so I have more than enough time.
I will just delay the biopsy processing so that both processors are
finished at essentially the same time. 

What I need is a shorter schedule for the biopsies so that the
detrimental affects of xylene and alcohol are minimized (and yes, we
still use xylene! And in case it matters schedule-wise, we use 10% NBFS
as well).

Thanks in advance.

There is some merit in doing the right thing rather badly,
but absolutely none in doing the wrong thing excellently!
