Re Tissue Processors

From:David Taylor Manager

Dear Tammy, 
We usually change the oldest of each reagent once a week. But, if you
have a busy week with lots of large fatty tissue blocks an extra change
of xylene and wax will help to optimise processing quality. When it's
quiet you may not need to change any or all the reagents for that week.
It all depends on how many blocks per run, what type of tissue and how
many runs per week.
Another factor to take into account is what type of processor you have.
The larger the reagent capacity per number of  blocks on a cycle the
less changes required. Also some processors have wax "cleaning" cycles
and condensation systems for the removal of alcohol and xylene fumes.
