CPS-20 Shaker for Incubators

Orbital CO2 Shaker

Shaker CPS-20 was specially developed for use in difficult environments such as CO2 and humidity.
The unit provides regulated orbital motion of the platform and is suitable for use in the CO2 incubator.  

The innovative CO2 shaker ensures reproducible results in cell culture growth.

A choice of 5 interchangeable platforms provide the possibility of performing various procedures and techniques in various cultivation vessels.

up to 98% humidity

CPS-20 - Orbital CO2 Shaker

CPS-20 has a brushless motor with a guaranteed lifetime of up to 35.000 hours.

The unit is equipped with a triple eccentric mechanism for platform movement that provides excellent balancing characteristics, superior reliability and quiet operation.

The specially designed remote control protects the electronics from the CO2 environment of the incubator. In addition, the remote control minimises disturbance to the incubator environment and the experiment in progress.


  • CPS-20 minimises the disturbance of the incubator environment and the ongoing experiment and thus contributes significantly to gentle cell cultivation.
  • The shaking unit (without the unit controller) is designed specifically for operation in CO2 incubators and closed laboratory environments at ambient temperature from +4°C to +45°C in a non-condensing atmosphere and relative humidity up to 98%.
  • The unit controller is designed for operation in cold rooms, incubators and closed laboratory rooms at ambient temperature from +4°C to +40°C in a non-condensing atmosphere and relative humidity up to 80% for temperatures for temperatures up to 31°C decreasing linearly to 50% relative humidity at 40°C.
