Re: TP1050 reagent changes

From:Connie McManus <>


How many blocks do you process in a week? (average).  I change my
solutions at the first of each month, with the formalin and 70% changed
2x in a month.  I change Paraffin every 2 months and they get a paraffin
clean once a week.  BUT, if I do 40 blocks in one day, I feel over
worked *g*.  Usually I get between 5 and 20 blocks/day and occassionally
there are no blocks.  Just curious.
