Eco-series Overhead Stirrer

The Eco-series are simplified overhead stirrers with easy to use controls and powerful high torque and high speed options. They are perfectly suited for anything from everyday light use, to heavy duty applications with high viscosity media as well as volumes up to 200l.

Quick-release chuck makes shaft swaps a breeze, and backlit speed display keeps your rpm info available at a glance.

Built in overload and overheating protections included.

For solutions which change viscosity during stirring please see our R 100 overhead stirrers which provide higher torque options, viscosity display, and finer control.
