Cole-Parmer® RotoFlex Tube Rotator

Adapt to different racks without tools to accommodate a wide range of tubes

These flexible tube rotators work with tubes sizes from 0.5 to 50 mL. The 360° rotation gently and thoroughly mixes samples. Additional features include an adjustable mixing angle from 0 to 90° for each of the 4 mixing panels independently.
The RotoFlex system has a fixed speed or 22 rpm for the 120V version or 18 rpm for the 240V version, and the rotational direction is reversible by simply tapping the rotisserie in the direction required. The RotoFlex Plus system has a variable speed range of 10 to 40 rpm, with a 1 rpm resolution. The Plus system also has an oscillation mode that agitates tubes while rotating for additional sample mixing. Additional rotisseries are available for purchase separately.
