GP Mixer System; 120/230 VAC

Mixer designed for reliability and durability|Ideal for light-duty mixing of water-like fluids Brushed DC motor with integrated overload protection Durable?no wear parts that require user service IP44 rated per IEC 60529 User-replaceable keyless chuck|Cole-Parmer GP laboratory mixer ensures accurate, dependable motor speed control with ?soft-start? feature and smooth, gradual adjustment to the speed setting. Constant speed is maintained electronically via automatic compensation for changes in load torque demands at both high and low speeds. Built-in motor current compensation minimizes speed drift with changes in load. Motor current limiting protects the system in case of a locked rotor condition. Output circuit protection protects against inadvertent output shorting. The mixer rotates at 40 to 4000 rpm with a maximum torque of 9.5 in-oz (6.7 N?cm). The speed control knob is used to turn on and set the speed of the mixer motor and provides a 100:1 adjustment range. The LED indicates the mixer is powered on when it is green. When it flashes, it indicates a limit condition has been reached, such as an overtemperature or over-current situation.
