S6 ImmunoBot™

The S6 ImmunoBot™ is a robotic arm plate loader extension fitting any ImmunoSpot® Reader. Utilizing CTL’s advanced gripper technology and compliance operation it can load up to 400 plates in a single run. Plate formats range from Petri dishes to 1536-well microtiter plates, with all well formats in between. The ImmunoBot™’s advanced magnetic kinematic coupling plate stack design ensures simple, precise stack placement and alignment, thus reducing downtime.

Unlike most robotic systems that need to be caged in a large/expensive enclosure, the ImmunoBot™ operates in safe-around-humans mode and can be used in an open environment. Its safety system will auto-detect and self-pause if any interference is detected.
