Intended Use
The Maxi Mix Plus is a general laboratory vortex mixer. It
is intended for applications where vortexing of single or
multiple tubes is required.
The unit consists of 1) a rubber mixing cup, 2) a silicone
rubber mixing platform complete with plate & screws
3) a two–position mode switch for touch-on or constant-on
operation. Model M63210-33 also includes a separate
ON/OFF lighted power switch.
General Usage
Do not use this product for anything other than its intend-
ed use.
Principles of Operation
The mixer incorporates a permanently lubricated motor to
drive the mixing head. A two-position mode switch
enables the mixer to be operated continuously or by
depression of the rubber mixing cup or mixing platform.
The mixer operates up to the speed of 3200 rpm (max.).
Suction cup feet are incorporated to prevent “walking.”

Environmental Conditions
Operating: 17°C - 27°C; 20% - 80% relative humidity,
non-condensing. Installation Category II
(overvoltage) in accordance with IEC 664. Pollution Degree 2 in
accordance with IEC 664.
Altitude limit: 2,000 meters.
Storage: -25°C - 65°C; 20% to 80% relative humidity.
Place unit on a stable, flat surface and plug into an appro-
priate outlet.
The power switch on the M63215 and the M63214 is a
combination ON/OFF and mode switch to enable
“TOUCH” operation. Move the mode switch to either the
“CONSTANT ON” position or the “TOUCH ON” position.
In the “CONSTANT ON” position, the rubber mixing cup
will oscillate continually. In the “TOUCH ON” position, the
mixing cup will oscillate when pressure is applied to the
cup. To stop the mixing action, release the pressure being
exerted on the mixing cup.
Model M63210-33 incorporates a mode switch to enable
“TOUCH ON” or “CONSTANT ON” operation. This model
also includes a separate lighted ON/OFF switch.
