IKA RW 28 Laboratory Overhead Stirrer

The IKA RW 28 is a powerful, mechanical laboratory overhead stirrer designed for mixing and homogenizing liquids and suspensions in both laboratory and industrial applications.

The stirrer features an adjustable speed range of 60 to 2,000 rpm, divided into two speed settings. This allows the stirring speed to be tailored to the viscosity of the medium and the desired mixing intensity.

The device is suitable for a wide range of mixing tasks, from the gentle stirring of liquids to the more intensive mixing of thicker substances.

A particularly practical feature of this configuration is the spring-loaded large stand, which allows the stirrer to be raised and lowered easily and with minimal effort. This simplifies the positioning of the stirrer above various mixing vessels.

The IKA RW 28 comes with two large stirring shafts—featuring mixing blades of 100 mm and 50 mm, respectively—along with two clamps and a spring-loaded stand.

Thanks to its robust construction and flexible speed control, this overhead stirrer is well-suited for use in chemical laboratories, research institutions, quality control, and product development.
