SECTION 2 — ROTOR-STATOR GENERATOR PROBES
2.1 INSTALLING ROTOR-STATOR
GENERATOR PROBES
Stainless steel and plastic Omni Tip™ rotorstator generator probes are easily installed
to the Omni THQ motor by means of a quarter-turn bayonet mount. Simply push the
generator probe into the motor housing as far
as possible, turn clockwise, and release.
The Omni THQ is ready to operate.
CAUTION: Remove the blue protective
cap from the stainless steel generator
probes before processing. Replace the
blue cap when not in use.
WARNING: The tip of the saw tooth
generator probe is sharp.
8
SECTION 2 — ROTOR-STATOR GENERATOR PROBES
2.2 HOMOGENIZATION
Insert the generator probe into the Omni THQ
motor. The depth of the generator probe in the
sample vessel can signicantly aect ow patterns within the vessel. This also aects processing eciency. As a rule of thumb, the generator
probe usually operates most eciently at a
depth of 1/3 (to 1/2) of the liquid height. Heavy
sediments may require deeper immersion, and
this processing depth can be optimized by
observing ow patterns and related processing
results. While processing, liquid can circulate
through the two holes at the bottom of the generator probe. The top hole of the stainless steel
generator probe should not be immersed in the
sample. Blocking the upper hole could result in
liquid being drawn into the lower motor bearing.
CAUTION: When using glass-lled Teon lower
bearings, do not operate the unit for extended
periods of time without immersing the bottom
of the generator probe in liquid or the sample
being processed in order to avoid premature
failure of the lower bearing.
WARNING: Reduce the risk of unintentional
starting; make sure that the power switch is in
the OFF position prior to plugging in the unit.
WARNING: DO NOT process pathogenic
material in an open container, since aerosols
created during normal processing could be
inhaled by the operator. Please call for
assistance in processing pathogens or other
material which require sealed enclosures.
WARNING: DO NOT use the motor
in a dangerous environment.
