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.
