Reax Control Vortexer

The precise one with speed scaling
 
All the outstanding features of the Reax Top's "little brother" can be found in this model: a rotational speed of up to 2,500 rpm and a 5 mm shaking orbit.
 
The electronic speed control and the scaling of the speed display allow precise settings. Applications that require a determined speed are thus shaken more gently. Shear force-sensitive organisms remain particularly protected by the constant speed in the low range.
