Magnetic stirrer drive minisprint
The minisprint from premex is an absolute hit. A micromotor paired with a minimised magnetic coupling, integrated into the styled red aluminium cylinder, that is the epitome of the minisprint.

Changing bearings is child's play
The threaded connection M18 x 1 mm can be extended and thus individually adapted to your reactor cover. This ensures that you can easily change the bearing from the underside of the reactor cover without dismantling the minisprint. Just loosen the lock nut on the lower edge of the cover and the output shaft, equipped with internal magnet, pulse generator and two bearings, can be pulled out.
