Recycled xylene is actually purer than new. We have found that this can cause GI biopsies to be crisper than when processed with new xylene, so we don't use it on our biopsy processor. Also, with some coverslippers, new xylene is a must. Other than a bad odor that can be remedied with acetic acid, I have had no problems with recycled xylene in the 20 yrs (yikes!) I've used it - with either of these brands of recyclers. Good luck!

Ofcourse, this was done without the lab's knowledge, but that is anotherstory for another time.  My question is how pure is the recycled xylene?Are you able to use the xylene on the processor as if it were new?  Iassume that you can use it for staining purposes, but I'm a bit waryabout using it for processing tissue.  The recycler that is here now isfrom B/R instruments and apparently another one from CBG Biotech will behere at the end of the month. Any assistance would be greatly appreciated.  Thanks........
