Re: [Histonet] Number of blocks before a processor change???
We rotate one of each solution type(including wax) every 50 blocks or every 2 runs(whichever occurs first). Helps counteract carryover from sponges and seems to work better and conserve a little on reagents than when doing complete change less frequently. Note: we rune a large number of small biopsies using sponges.

Hello: We currently change our processors every 5 runs. I am thinking it would be more cost and time effective to count the number of blocks before doing a change. If you count your blocks could you share with me at what number you do a change. We run all types of tissues. We use a gallon of reagent in each position. Vip5.

Re: [Histonet] Number of blocks before a processor change???
I always counted the number of blocks processed per run. When my VIP reached its maximum (e.g. 300 blocks), I changed all the alcohols of less than 100%, and moved "down" the 100EthOL, the xylenes and the paraffins (meaning eliminating the first 100 EthOL, xylene and paraffin, and replacing the last).
