RE: Xylene expiration date.
|From:||Jim at ProSciTech <email@example.com>|
Petrol (gasoline) contains additives and there is some separation during long
term storage. Xylene, however, is a stable chemical molecule and I rather doubt
that this falls apart in any way during reasonable storage conditions. I am
rather surprized that they give it an expiry date. I expect that the "bottler"
thought it was a good idea; perhaps it would cause people to throw out old and
buy new solvents.
I am amused that you are reluctant to take a whiff (not that this would tell
you much). Not many years ago histologists virtually lived in xylene vapour
saturated labs. Certainly its not conducive to good health, but the problem was
not the odd whiff but chronic exposure.
Happy New Year
