Dear Alexey,
being involved in the development of the 'fixed needles + a few'
robots and 96-well plates early on, I wonder about your bad experiences.
You seem to say that the Phoenix requires more maintenance than the
Mosquito - how long have you had that Phoenix or what model is giving
you the trouble?
For the electrostatics issue: it’s the plates that are electrostatic
not the robot. This is a common lament for plastic plate users, and
the Intelliplate designed to go with the Phoenix comes in anti-static
bags as used in electronic component packaging. Other plates have anti-static
coating, and there may be other tricks as well to avoid electrostatic charge
(comments anyone?)
Also, the limitation of the 200+200 you claim for the Phoenix seems extreme,
users have set up 200+200 already with the old hydra+1 contraptions,
and 100+100 seems to work reliable with the Phoenix (maybe some
users can comment?). Could it be that yours is not set up correctly? I am
sure ARI will be happy to send a European rep by to check.
Best regards, BR

we have recently tried the new lid mentioned below. It works very well, Mosquito makes 3 hanging drops 96 well plate in 3-4 minutes! The film is very easy to handle and it is very transparent. The price for the lid is significantly reduced: from 13€ before to 4€ now.
Comparing to Cartesian and Phoenix robots the Mosquito is REALLY maintenance free machine, especially the third generation insect where many 1st and 2nd Mosquito generation users advices have been implicated.
