Digital Mixer, 30 to 2000 rpm, 115 VAC

Maintenance-free, continuous-duty mixers ideal for general laboratory use|Simple, reliable mixers for volumes up to 4 gallons (15 liters) and viscosities up to 10,000 cps|Stirring speeds up to 2000 rpm are automatically maintained as viscosity changes|These mixers feature a through-shaft design that permits adjustment of shaft length and impeller depthallowing you to place or remove mixing vessels without repositioning the mixer. The motor and drive unit are conveniently integrated into a compact aluminum 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.
