The Cole Parmer 750-0230 General-purpose/through shaft mixer head offers a speed range of 23 to 2300 rpm with 1/10 hp PMDC motor. Through shaft design lets you position the propeller without moving the mixer head. Maximum torque is 45 in-oz. Accepts only 3/8" dia. 1/10 hp motor with adjustable through-shaft precision collet

The solid-state controller offers precise speed control with a 100:1 adjustment range. A separate "forward / off / reverse" switch works independently from the speed control dial - allowing you to repeat mixer speed settings from one run to the next. An LED indicates when power is on. Motor speed is maintained within 10% despite changes in line power or torque load conditions. Speed stability is critical for materials that change viscosity as mixing progresses.
