Hi Chen,
I had a similar condition before (reservoir solution with 10% dioxane) and an
oil-based cryoprotectant (66.5% w/w paraton-N, 28.5% paraffin oil and 5%
glycerol) worked for me. Please check this paper out:

In addition, have you tried cryoprot
igher
viscosity you may not have to "chase your crystals" through the drop.
Hope this helps a little.

Dear all,

Dear all,
I am now optimizing a hit which contains about 30% 1,4-dioxane using
hanging-drop vapor diffusion at 25 degree. I am having a hard time to
reproduce the results: most of the times the drops are either dry in one
day or full of precipitate, and only occasionally could I get small
crystals
