Hi all! Recently, our lab has been experiencing a hazy, lack of detail at
high magnification on all of our H&E's and special stains. I've changed ALL
reagents, cover slips, slides and mounting media yet still no change in
results. Could it be the formalin? We prepare 55 gallons of 10% NBF at a
time and the problems started around the same time a new batch of formalin
was made. Any ideas would be greatly appreciated. Thanks.
