Dear Bostjan,
It might not be exactly what you need but TECAN with their Genesis
workstation (8 needles in // that can pipette .5 µl without problem)
combined with Greiner 96 sitting drop well plate (with 3 micro wells/ well)
can do a pretty good job at crystallisation.
bye,
Laurent Chantalat

Objet: [ccp4bb]: multi-channel pipettors for crystallization

Dear Bulletin Board,
We have been trying to convert to 96-well plates and multichannel
pipettors for crystallization. We have tried a few pipettors (both
manual and automatic; Eppendorf, Genex, Biorad) with very limited
success. Among other, we encounter the following problems:
- The channels are not well aligned with the wells (particularly
Eppendorf; the tips are too long).
- The pipettors do not accurately pipette small volumes (0.5-1 ul),
despite trying many different types of tips.
- The blowout feature introduces bubbles in drops.
Could people share their experience about using multi-channel
pipettors and 96-well plates, in particular:
- What drop size do people use?
- What brands of pipettors do people recommend?
Any other information regarding this topic will also be very welcome.
Merry Christmas and Happy New Year!
Bostjan
