Cole-Parmer Stir-Pak 4558-03 Solid State Speed Control

The Cole-Parmer Stir-Pak Analog Speed Controller is two motor shafts that give you two mixers in one. The direct-drive shaft provides high-speed, low-viscosity mixing; switch to the gear-reduction shaft for your low-speed, high-viscosity mixing needs.

Rugged, permanent-magnet, totally enclosed, nonventilated (TENV) motor has permanently lubricated ball bearings. Gear-shaft gear ratio is 20:1.

The solid-state controller maintains speed regulation better than ±2%—critical for materials that change viscosity as mixing progresses. Improved torque limiting feature protects against motor gear failure. Motor has an IP24 rating; controller is totally enclosed and has an IP22 rating for protection against dust and water. Controller complies with UL and CSA 61010 standards. A 6-ft (1.8-m) cord connects the controller and the motor.

Price is for one controller.
