I sent this personal reply on wednesday to Madhavi Nalam's original
question.
In the light of recent comments I'm posting it to the BB to support TTP
labtech and Mosquito!
Some of the points have been made by others now, excuse the repeats!
We at YSBL have been very happy with our mosquito. We use it to setup
sitting drops with the MRC Wilden plate, this can be for screening or
optimisation (not always necessary to go to 24-well format). You can
also setup hanging drops, this can work better if detergents are
involved. A new lid has just been released from TTP that costs £2.50
and takes 3 drops per well but we havn't tried this yet. You will need
another robot (or multichannel pipette) for transfering the screen
solutions.We use the hydra from alpha-helix ltd with flexible needles so
hard to break.
The phoenix robot does both jobs and seems popular. The Douglas robot
has been mentioned, the Cartesian is the other main robot in use but I
don't have any personal experience of it, I've heard it is quite high
maintenance.
Good luck with your purchase!
