Many thanks to all who replied!
I got emails from people who are also interested, asking to summarise the
results, so here is what I’ve got so far:
1) Liquidator 96 200mkl from Rainin. Everyone agrees it works well and is easy
to use, but tips from Rainin are required.
2) Integra VIAFLO 96. Tips also needed, but not specialised ones. It is also
automatic, which Liquidator apparently is not.
3) Multichannel pipettes, ranging from 96 - 12 to even 8 channel
4) Old Hydra
More expensive options, and more versatile robots than can dispense screens in
addition to other functions:
5) Art Robbins Scorpion
If I find out something else, I’ll let you know.
