RE: Alcohol and Xylene Recycling

This is from our waste manual:

Quality Control of Recycled Solutions
1. Xylene Solubility of Wax (1)
1. Take 1 gram of wax and mix in 20ml of xylene
2. Record time for full dissolution
3. Check for any undissolved residues and contaminants

2. Xylene miscibility
Take 20ml of xylene and add 20ml alcohol, recording the appearance of the solution


1. Massey, J., (1993) "Quality control for tissue processing" Lark News 1(3):6-7.

This doesn't actually test the purity of the xylene, but it does give some confidence in the use of the xylene for routine Histo use.

Hope this helps,

I know many people are using stills these days to recycle alcohol and
xylene.  It's easy to check the alcohol with a hydrometer to determine
percent of the distilled product, but has anyone come up with a method of
checking the xylene for purity without having to send it somewhere for
analysis??? Thank you
