SECTION 1. OMNI MIXER & MACRO HOMOGENIZERS
The Omni Mixer and Omni Macro Homogenizers are variable speed, post-mounted
homogenizers. The Omni Mixer is powered by a 600watt, 18,000rpm motor, and the
Omni Macro by an 1,800watt, 20,000rpm motor. Both utilize a broad range of sealed
chamber assemblies, high shear knife assemblies, as well as a choice of seven different
diameter autoclavable rotor-stator generator probes. The versatility of these units is
unparalleled and makes them the ideal choice for general purpose laboratory
homogenizing.

1.3 ASSEMBLY OF THE OMNI MIXER OR OMNI MACRO
To assemble the Omni Mixer or Omni Macro Homogenizer please refer to the figure,
and:
• Insert the support post into the support base. Secure the set screw through the
back of the support base into the groove in the support post, using wrench PN
60241 (1/8 in. Allen) provided.
• Place the clamping knob assembly in the motor support housing with the two flat
surfaces on the clamping mechanism facing the support post hole. The clamping
knob assembly may be used either on the left or the right side of the Omni Mixer
or Omni Macro.
• Slide the motor support housing onto the support post and clamp it into place
with the clamping knob assembly. The motor support housing should be
positioned over the two longer legs of the support base.
SECTION 1. OMNI MIXER & MACRO HOMOGENIZERS
CAUTION: To prevent damage to the drive mechanism, never operate the motor
without a complete chamber assembly or generator probe in position.
CAUTION: Never operate the motor with the generator probe (or sealed chamber
assembly) partially threaded onto the motor. To prevent damage to the motor and
attachments, follow the instructions in Section 2.2 to assure the generator probe (or
sealed chamber assembly, Section 3.4) is fully threaded into the coupling adapter.
NOTE: If you experience excessive vibration, heat, or bearing wear, please contact
technical support at 1-800-776-4431

1.4 GENERAL OPERATING PROCEDURE
The speed of the Omni Mixer or Omni Macro may be regulated to achieve optimum
results when working with different materials. A speed selection knob is located at the
side of the unit, as is a separate “OFF” or “ON” switch. When in the “ON” position
the motor speed can be varied from 0 rpm to maximum speed. Select the optimal
speed for each different combination of sample and accessory for best processing
results.
WARNING: Keep all housings in place and in working order. DO NOT use the
motor in a dangerous environment. DO NOT force the unit to do a job that it was
not designed to do.

SECTION 1. OMNI MIXER & MACRO HOMOGENIZERS
WARNING: Improper connection of the equipment can result in a risk of electric
shock.
WARNING: Reduce the risk of unintentional starting by making sure that the motor
switch is in the “OFF” position prior to plugging in the unit.
1.5 QUICK CONNECT COUPLING ASSEMBLY (optional)
The Quick Connect Coupling Assembly is an optional accessory for the Omni Mixer
and Macro. To use, attach a Quick Connect Adapter to your chamber assembly or
generator probe. Next, slide the Adapter into the Quick Connect Coupling and a
retaining ring positions into place for a secure hold. To disconnect, simply slide the
ring upward and the processing accessory is conveniently released.
1.6 DETERMINING MOTOR SPEED
To determine motor speed during operation, an optional tachometer, PN 01009, may
be inserted into the Omni Mixer or Omni Macro through the top of the motor as
shown by removing the protective snap cap.
