Cole-Parmer SP Laboratory Overhead Mixer

Variable speed mixer designed for reliability and durability

Cole-Parmer SP 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 50 to 2500 rpm with a maximum torque of 91 in-oz (64 N·cm) and has a through-shaft capability. Bracket hardware is preinstalled to enable installation of the adjustable tilt mounting bracket. The motor cable connector has a locking mechanism when the cable is connected to prevent unintended disconnection in the event of accidental force on the motor cable.

The variable-speed controller is used to turn on and set the speed and direction of the mixer motor. Easily switch the direction of rotation using the Forward-Off-Reverse switch. The LED indicates the mixer is powered by turning green and flashes when a limit condition has been reached.
