Apparatus consists of a thin film tube, 400mL borosilicate glass beaker, cover assembly with bath stirrer, sample pump rotor and cooling coil, 6V lamp with line cord, and drive motor. A positive drive pulley system rotates sample and bath stirrers. Two thermometer ferrules and mounting hardware are included. Available Powertrol heaters provide variable stepless control and a reference dial for repeatable control of heating rate. They also provide a low voltage receptacle for the 6V lamp.
