cryschem crystal growth chambers

[GLUCKSMAN LAB- STRUCTURAL NEUROBIOLOGY]

Dear Xtalers-

	I had just joined this bulletin
board, so I do not know if this question
has been raised in the past.

	Are there concerns in using the
clear tape provided with the cryschem
mdv/24 crystal growth chambers.  I am
a bit worried about introduction of organics in
adhesive, gas permeability (I did notice 
that some of our earliest trials of 8 months ago
were dry) which may give rise to irreproducibility.  

	What do other people do.  We have also tried
the grease 'n' glass approach with falcon plates
and those of ICN.

Thanks,

Emer Ferro
