R100CT Pilot Plant Overhead Stirrer

R100CT Pilot Plant Overhead Stirrer

Price: $3,195.00

Vol: 200L | 600 NCM | RPM: 500


Here’s our top-of-the-line overhead stirrer designed especially for pilot plant applications processing samples to 200 liters.  Its powerful 240-watt motor easily delivers up to 600 Ncm torque energy.  Use it with confidence when stirring medium and high viscous materials (10,000 to 100,000 mPa.s) at speeds from 50 to 500 rpm.  If that’s not fast enough higher speeds to 6,000 rpm are available on request.   And don’t worry about spills – the soft start-up feature keeps samples from splattering out of the beaker or flask.

Operation is simplified thanks to the programmable torque limits and maximum/minimum speeds.  Speed and torque are simultaneously displayed on the digital readout.

Set the program to stir from 1 minute to 99 days.  Lab staff won’t be bothered by operational noise thanks to its quiet operation.   This professional unit can be operated remotely (and data collected) by a PC via an RS 232 interface.

As with all CAT overhead stirrers the R100CT pilot plant stirrer self tests to protect against overload and overheating, and can be paired with a variety of stirrer configurations.
