Rütten magnetic stirrers

Patented system for mono or twin magnet and suspended stirrer 1 to 350 litres (0.25 to 100 US gal).

Sterile Storage System (SSS)

Application :
Blending Mixing Suspension Dispersion Homogenisation Heat transfer

Operative range :
Vaccines Sterile liquids Injectables Nutrient media Suspensions

The Rütten Magnetic Stirrer system is ideal for applications where sterility, hygiene and system simplicity stay at the forefront of requirements. Rütten Magnetic Stirrers are composed of twin stainless steel bars with magnetic cores. The stirrer suspension tube is welded in the vessels' head plate, usable as product harvester.

Smooth rotation of the mixing bars is ensured by a silicon carbide bearing for heavy duty operation. High precision speed adjustment from 0 to 600 rpm make Rütten stirrer technology stand out from the common. Models with reduced speed range ensure safe processing for particularly share sensitive media. Smart construction of the magnetic stirrer assembly facilitates quick and thorough cleaning.
