Page 12: Section 3 - Sealed Chamber Assemblies
3.1 SEALED CHAMBER ASSEMBLIES Sealed chamber assemblies are available as separately ordered items for use with the Omni Mixer and Macro. They consist of chambers, many of which are fluted to facilitate mixing by inhibiting swirling, gasket screw on cover seals to inhibit aerosol release, a shaft assembly, and a sharpened stainless steel blade, or generator probe. - Page 13 Omni Mixer by using hard materials, such as glass beads. The Omni Mixer will act as a “bead mill”, agitating the chamber while the hard materials do the work. Since sharpness is not essential, a dull blade should be used.

4.2 DISPERSION IMPELLER ACCESSORIES Two inch diameter dispersion impeller blade accessories are available for the Omni Mixer product line but are not supplied with the instrument.

Page 17: Section 5 - Maintenance
Installation of the coupling is the reverse of these steps. 5.3 MOTOR BRUSH MAINTENANCE To a large measure, how well your homogenizer performs its job is deter- mined by the condition of the carbon contact brushes (P/N 61810). If brushes require replacement, the unit may run at a reduced speed and make unusual noises, or it may run sporadically and lose power. -
Page 18: Bearings And Lubrication
SECTION 5 — MAINTENANCE If the brushes are not installed properly they will not contact the commutator and the motor will not run. After replacing the brushes, make sure to remove the flexible rubber coupling, place the motor on a clean surface, and run it freely (no-load, without a generator or chamber assembly attached) for 15 to 30 minutes before using the unit to process samples. -
