The CERTOMAT™ RM with its powerful drive and digital control of speed and time is the classical workhorse for everyday lab work.

Long service life and quiet running are guaranteed by the proven construction with a brushless motor, the strong Poly-V belt and the triple-excentric drive system. The shaking intensity can be modulated by selecting an amplitude of 25mm or 50mm.

The CERTOMAT™ RM is equipped with visual speed alarm, a memory function for automatic re-start after power failure and an analogue out for external recording of speed.

In addtion, the CERTOMAT™ RM features adjustable mass compensation. While all other benchtop shakers have to use a fixed weight to compensate imbalances caused by the movement of mass, the CERTOMAT™ RM has a compensation weight that can be moved along an axis to the position optimally counteracting imbalance. This patented feature makes it possible to run even high loads at maximum speed without increased vibration and running noise. Setting of the compensation weight is done from the outside of the housing with a simple tool.

  • High load and high speed applications
  • Adjustable mass compensation for maximum speed
