Re: Trouble Shooting
Responding to the message of
from email@example.com (Salvacion S. Delovino):
So glad to hear everything worked out for you! I am sure that the mistake will
not recur with your MLA....it is a hard lesson....but an effective one!!
The reasoning behind running the tissues back through the alcohols to water is
to REhydrate them. You are actually putting water back into the dried out
tissue, and then reprocessing. Never thought of using the cleaning cycle
though....there were no "cleaning cycles" on processors when I started in
Histology!! The old processors used to get "hung up" every now and then and the
tissues would all dry out....that's when we would run them back and start over!!
