Hi Ruth,

Creative Waste Solutions has a molecular sieve product for extending the
life of xylene or xylene substitute on stainers, for the steps at the end,
after 100% ethanol. It does work and with two sets, you just rotate dried
ones for the wet ones after about 200 to 400 slides. You can call Rex
Johnson (no relation to me) 1-503-784-1232. They also have a great product
for recycling alcohol and buffered formalin that many labs use and save a
ton of money with in reagents they don't have to purchase as often. He can
fill you in on the details.

Good Luck,

Hello histonetters,
I have just read an article about molecular sieve beads being used in
xylene to extract the water, and therefore extending the life of the
xylene indefinitely.  This article was given to me by a cytologist. She
came across it on the cytology equivalent to the Histonet. So my
question is, has anybody in histology used this method to keep xylene
moisture free? And if so, do it really extend the life of the xylene
Any and all information is greatly appreciated!
