The shaker drive is unique due to the magnetic coupling and the hermetic separation of the motor from the incubation chamber, this is fundamentally different to conventional shakers. Based on good experience with the Unitron® and Multitron® we have done away with the usual arrangement of bearings. Therefore, the floor of the chamber is free of both bearings and eccentrics. By virtue of the excellent sealing of the magnetic drive and electronics, the dreaded problems of flask breakage are finally solved and cleaning of the machine reduced. The bottom of the chamber is easy to clean and can even be rinsed with water. Additional protection for the culture is provided by an overheating cut-off switch and a potential-free alarm output from the interface. It is given that the unit will re-start.
