  • Adjust the mixing angle of each rotisserie platform separately from 0 to 90°

  • Change the mixing direction to suit your application needs
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 120 V version or 18 rpm for the 240 V 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.
