Introduction

Intended Use

The Type M37600 vortex mixers are general laboratory
vortex mixers. They are intended for applications where
vortexing of single or multiple tubes is required. Vessels
with closure tops up to a maximum of 125 ml can also be
vortexed.

The unit consists of 1) a mixing surface disc, 2) a three­position power switch and, 3) an adjustable speed control
(See Figure 1).

Principles of Operation

The mixer incorporates a permanently lubricated motor to
drive the mixing platform. A three-position power switch
enables the mixer to be operated continuously or by
depression of the silicone rubber top. The speed of the
mixer is regulated by an adjustable rheostat. Also, suction
cup feet are incorporated to prevent unit movement.
