RE: Humidity and Xylene Subs

From:"Geraci, Maria"

Hi Linda,

We have the same problem in our laboratory in the summer and I use Molecular
Sieves 3A, 4-8 mesh put out by ACROS Organics.  I believe the order number
is 197245000.  And yes, they really do work.  I just add them to the xylene
and I change them when I change the xylene.  

Good Luck

Hi Fellow Histonetters,

Now that summer and humidity is upon us our lab is
having the usual "bleeding eosin" problem. Last year
we were staining by hand but this year we were lucky
enough to get an automatic stainer which we thought
would take care of the problem - guess again.  We are
using Richard Allan Clear Rite 3 which I know loves to
absorb water.  I remember some literature about
"absorbant beads" to place in the Xylene Subs to help
with this problem.  Since I cannot find the literature
- does anyone know the name, supplier, price, etc. and
most important do they work?  Thanks!

Have a great holiday!
