[ccp4bb] opentrons pipetting robot

Hello All, I've just learned about the opentrons pipetting robot, which appears to be quite affordable relative to other robots. I'm wondering if anyone here on ccp4 bb has any experience with it - for creating crystallization screens and/or setting drops? Best, Doug - Douglas

Re: [ccp4bb] how to improve the diffraction quality of the crystals and avoid icerings

Hi Yuvraj, Here are some thoughts in addition to what's been suggested already: 1. A good recent reference is here: http://journals.iucr.org/f/issues/2015/06/00/en5564/index.html 2. The image you sent suggests cubic ice, indicating a higher glycerol concentration (maybe 35 or 40%) is needed.
