I have long thought about developing an open-source crystallization robot based on the now ubiquitous 3D printing linear motion systems. They are certainly plenty precise for doing crystallization plating. Probably having two heads, a 12-channel syringe system for screen dispensing and a second hea

The opentron liquid handler is currently in what I would consider an alpha stage of development in both hardware and software, when compared to more expensive liquid handlers produced by companies like tecan, hamilton, agilent, etc. It is considerably less useful due to the lack of software contro

Good morning and Happy New Year to you In brief, it can be used to create screens although programming multiple ingredients with varying viscosities will initially be a fairly steep challenge since the software is not specific to crystallization. It can be done though and provided that you can re-

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 J
