RE: Xylene/Xylene Substitutes
|From:||"MacDonald, Jennifer" <firstname.lastname@example.org> (by way of histonet)|
To my knowledge NO xylene substitute is safe for sewer disposal.
We use the Leica coverslipper also. We use Clear-Rite 3 on our stainer
(also Leica), but we have a container off of the stainer to put the slides
in before they go on the coverslipper. It is a mixture of about 2/3 xylene
and 1/3 Clear-Rite 3. We have had success with this. We shake the excess
clearing agent off of the slides before they go on the coverslipper. Your
problem sounds like excess clearant that is evaporating and causing the air
