[RASMB] rigorous solvent condition

[mitrana at mail.utexas.edu]

Hi Zhenli
Of the top of my head, I believe they are both suitable with the  
epon-charcoal center pieces. However I suggest you check the website  
of Ultrascan/CAUMA run by Borries - I think they have a solid list of  
all the chemicals/solvents and their suitability to different  
centerpieces.

On another matter, and a question to other RASMBer's, can 5% urea (~  
0.8M) give rise to a gradient in a SV run?
