I can only comment on the Precise robots but they are everywhere in labs. Definitely safe and actually much cleaner than having humans move plates around. There’s probably nothing dirtier in a lab than us humans constantly breathing out bacteria and water droplets, not to mention shedding hair and skin cells.
Anybody care to take some guesses on how many PF robots are out there moving microtiter plates around? 5,000? 10,000? 20,000?
