I think Dr. Loll has expressed my reasons for my original suggestion. When there are skins, evaporation, etc., "crystal catching" can be a real pain, and then you break your best crystal...
 
What if you could just go up to your intended crystal and vacuum it up, and whisk it away to the dewar?

Pretty cool, but the examples shown are all gigantic. Having just spent a frustrating several hours chasing 5 um crystals, I'd give half my kingdom for a simple way to catch THOSE little buggers (damn you, surface tension!).

Have you seen the Crystal Catcher system, developed in Japan?
Some of us saw it at a recent IUCr meeting, but I don’t know anyone who has tried it with their own proteins
