During the testing boom for the pandemic, mag bead based separations took up a large portion of the time processing each sample.
This is an apparatus meant to be used on deck on any liquid handling platform.
The point behind this design was to offload the heating, shaking, separation, and “plate movement” functions to a single peripheral while allowing the liquid handler to focus solely on pipetting functions. I picture six or eight of these integrated in one system increasing throughput quite a bit.
This was designed to use all off the shelf parts such as NEMA steppers, Arduino controllers, and other misc. hardware.
Haven’t done much with this design lately, but thought others might appreciate it.
