Hi everyone, Sorry to ask a question that is not really related to phenix. I hope someone here will be able to help me out. I have a few crystals at hand right now, but I will not be able to look at them for at least another month or so due to beamline schedule. Do you think I should freeze them now or wait till I have my beamtime, or it is crystal dependent? Thanks in advance.

It is crystal dependent, but if they are big enough I would freeze them now. I have seen many crystal forms deteriorate over time and wouldn’t take the risk of that happening. It can happen though that old crystals get better (presumably due to slow dehydration of the drop), but I think these cases are fairly rare. Bert
