We only recycle xylene which we've tested purity and was close to 98-99% and is used in both H&E staining and processing with no issue. I've done 8 hour xylene vapor monitoring in our recycling room, while recycling was occurring, and the results were 6.0ppm where the OSHA exposure limit is 100.0ppm.

While I can agree that recycling alcohol and xylene is both environmentally and economically advantageous, technically it's awful. There's no way to make used alcohol and xylene as pure as it was originally. There's also the issue of fumes from recycling a solvent. The company I had used years ago swore that there were no fumes when using their machine but the personnel working in the laboratory would vigorously disagree. Barbara S.

Morning All! I have heard for years the general problems with using recycled alcohols on H&E stainers, but do the same problems occur when using recycled xylene? Thanks! Jeanine H.
