Cole-Parmer offers Electronic Overhead Stirrers. These stirrers feature a through-shaft design that permits adjustment of shaft length and impeller depth—allowing placing or removing mixing vessels without repositioning the mixer. The motor and drive unit are conveniently integrated into a compact aluminium and thermoplastic housing with easy-to-use controls and a clear LED display of rpm. Mixers feature infinitely adjustable stepless speed control. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in fluid viscosity. Quiet, fan-cooled motors feature thermal overload shut-off, and an efficient heat-dissipating design to ensure a long service life. Motor is maintenance-free and rated for continuous duty. Safety circuits ensure automatic cut-off in an anti-stall or overload condition.
