We're using an Art Robbins Scorpion. In a typical configuration it will hold three racks of either 8 50 ml Falcon tubes or 24 15 ml Falcon tubes. We use ours mostly to dispense 96 well optimization blocks with 250-500 uL per well to feed our Gryphon. We routinely dispense 50% PEG solutions, but of course this will be somewhat slow for accuracy. Software is easy to use--my undergraduates program and use it routinely. PEG blocks take 20-30 min, non-viscous blocks maybe 10 min.
