Laboratory Scale See-Saw (Wave) Rockers


The RCK-21 and RCK-22 series has been discontinued. Please contact our Flow Engineering department for a viable replacement.

The RCK-21 and RCK-22 use a see-saw motion to create wave-like mixing process. The mixers are specially design for any flat vessels, such as culture flasks, petri dishes etc., generating a gentle and full mixing action. More platforms can be added to the rockers by adding stacking system to accommodate more samples. There are two models for this type of the rocker: Both of them are microprocessor controlled. The digital model RCK-21 provides digital timer with up to 9 hours setting and speed control in 1 RPM increment. The RCK-22 model provides 2-hours timers (in 10 minute integral) and 10 steps speed control without digital display as shown in MOS.
