Pray for a Preddator
Redd&Whyte worked with pharma to develop a line of small, versatile dispensers for the research community, which co-founders Martyn Hanlon and Roger Poole, M.D., were happily showing off at ELA. “We knew industry needed this equipment,” said commercial director Hanlon.
“The Preddators can dispense any fluid from DMSO to oil, in any dispense pattern,” he added, with the ability to mete out detergents and surfactants with virtually no foaming. “They will even do grease and cells.” Hanlon boasted that the instruments can fill 300 1,536-well plates with the worst, stickiest protein before the tips begin to clog.
These modular, upgradable instruments come preloaded with more than 100 programs in their flash memory, and can also be controlled by a PC or integrated into an automated platform, enabling them to fill any plate up to 3,456 wells, as well as dispense to custom-patterned plates and surfaces.
Preddator’s open-architecture software makes it useful for applications as diverse as PCR, multispotting arrays, protein crystallography, and dispensing gels. Solenoid valves dispense volumes from 20 nL to 200 µL. It comes in one- and four-channel versions, with the four-channel Preddator S4 capable of filling a 384-well plate with 1 µL in 15 seconds, and a 1,536-well plate in a minute, according to the firm.
