Ingenieurbüro CAT M. Zipperer GmbH Overhead Stirrer R 50
Long lasting stirrer with electronic feed-back speed control. This stirrer is well suited for all stirring needs of moderate viscosity in any laboratory, either professional or classroom. The use of the instrument is advantageous where the speed adjustment of stirring processes has to be reproducible -such as when test series have to be carried out one after the other under comparable conditions, and when parallel experiments with several stirrers must be made simultaneously. The speed is steplessly adjustable from 50 to 1600 rpm. The electronic feed-back type of control guarantees exact control and high precision so fluctuations in the viscosity of the media being stirred will not occur. The stirrer has a hollow shaft with a 10.5 mm bore and a heavy chrome plated chuck to avoid corrosion.


Brushless laboratory stirrer:
A brushless motor has essential advantages compared to a brushed motor: small size, high speeds, high torque, high efficiency and nearly silent operation Brushless motors produce no "brush sparking" because the brush unit is replaced by electronic commutation. This means there are no carbon brushes that require replacing and the motor has an above average working life.
Practical advantage: Stirrer motors with electronically commutated DC motors are compact, light and extremely powerful. Other features of our brushless laboratory stirrers are listed in the following section.
