Introduction
The Cleaver Vortex Mixer is a general purpose laboratory vortexer. Mixing speed is adjustable
up to 3,400rpm. A three position switch allows the mixer to be operated continuously or by
“touch” activation. The shaking mechanism is specially designed to offer enhanced stability

under various loads. The metal baseplate and rubber feet provide additional stability and prevent
the unit from “walking” across the bench, even at maximum speed.
Read this manual thoroughly before attempting to operate the Vortex Mixer. All persons
operating this piece of equipment should review the Safety Precautions section of this manual.

Unpacking the Vortex Mixer
Upon receipt of the Vortex Mixer, examine the exterior carton for damages. In the event of
shipping damage, a claim must be filed with the transportation carrier within 10 days of receipt.
Save all packaging for inspection by the carrier.
Carefully unpack the unit and check for completeness. Included in the carton should be the
following:
Vortex mixer with cup head
Line cord
Instruction manual
Warranty card
If any of these items are missing, contact Cleaver immediately. Save the original packaging until
the unit has been shown to be operating properly.
Verify that the unit is rated for the proper voltage by checking electrical / serial no. label on the
back.
Installation
Locate the mixer on a level, stable surface near a grounded electrical outlet. The surface should
be clean and free of dust to ensure that the feet grip the surface firmly. Allow sufficient clearance
on all sides of the unit for proper ventilation.
With the power switch in the OFF position, plug the power cord into a grounded receptacle.
Operating the Vortex Mixer
All operating controls are located on the front panel. The power switch, located on the left side of
the panel, has three positions –ON, OFF and TOUCH. When set to the TOUCH position, the
mixer is activated by depressing the mixing head. When pressure is released from the mixing
head, operation will stop. When set to the ON position, the mixer will operate continuously until
the switch is moved to either the OFF or TOUCH position.

The speed control, located on the right side of the panel, is continuously adjustable. Oscillating
speed increases at a non-uniform rate to a maximum of 3,400rpm as the knob is turned
clockwise. Before turning on the mixer, set the speed control to the minimum.
To begin operation, move the power switch to either the TOUCH or ON position and turn the
speed control to the desired setting. If the power switch is in the ON position, the shaking head
will begin moving immediately. If the power switch is in the TOUCH position, operation will begin
when an object is placed on the shaking head and slight pressure is applied to depress the head.
Shaking will cease when the object is removed and pressure released.

Accessories
Several additional shaking heads are available for the Vortex Mixer. To change heads, remove
the cup head by holding the housing securely while pulling up on the head. An optional head can
then be placed on the drive post and secured by pressing down firmly on the head. When
removing the accessory heads, pull up on the black plastic connector only. Pulling up on
the foam or metal plate can cause damage to the accessory head.

Care and Maintenance

Warning: Disconnect the vortexer from power source before attempting any cleaning or
maintenance procedures.
After each use, wipe down the mixer with a soft cloth. Do not immerse the unit or pour liquids
over it as electrical shock may occur. Clean up any spills immediately taking the proper
precautions. If required, the shaking head may be removed. First, disconnect the vortexer from
the power source and then remove the combo-cup head by holding the housing securely while
pulling up on the head. The head may then be cleaned with a mild detergent. Be sure the head
is thoroughly dry before replacing it on the unit.
The motor and shaking mechanism in the Vortex Mixer require no routine maintenance or
lubrication.
