Hi. I am trying to optimize a commercial crystallization condition that contains glycerol. So far, I have not been able to even reproduce the results from the initial screen, and I thought that this may be due to poor quality glycerol (among other possibilities). I believe that the glycerol that I'm using is reagent grade and am not sure what company it is manufactored by. Can anyone recommend a supplier and grade of glycerol suitable for making crystallization screens?
Thanks, Matt
