[Histonet] IHC humidity chamber?

[J m]

salut,

Does anyone know of a supplier in Canada for the IHC humidity chambers. I 
used to have a black plastic one with a clear lid but I don't know where it 
came from or where i can get another one. I am tired of having slides dry 
out during overnight incubation in the make-shift chambers I have tried to 
construct. Regular tissue sections seem to "hold" the solution on the slide 
better than tissue arrays which are more apt to losing there solutions. I 
don't like using water repelent pens to circle the arrays but any 
suggestions would be appreciated.
