[Histonet] Paraffin Question

[Rene J Buesa]

You cannot "measure" paraffin changes by dates because it is used as a function of the number of cassettes processed. I always used VIP that have 4 paraffin containers. I used to keep track of the number of cassettes processed daily. When I got to as many cassettes as the VIP was designed to (e.g.: 300 cassettes for VIP 300) I discarded the first paraffin, moved forward #s 2 and 3, and added new paraffin in #4.
By dpoing this the #1 was discarded when the VIP had processed 900 cassettes.

How often are people changing/rotating their paraffin?  In other words the dirtiest paraffin is how many days old?
