SECTION 3 — ROTOR-STATOR GENERATOR PROBES
The upper hole of the tube and collar assembly should be left un-
blocked to allow the sample to circulate through the generator probe.

3.3 OPERATION

Insert the generator probe into the Omni GLH motor and remove the
blue protective cap from the end of the generator probe. The depth of
the generator probe in the sample vessel can significantly affect flow
patterns within the vessel. This also affects processing efficiency. As a
rule of thumb, the generator probe usually operates most efficiently
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 flow patterns and related processing results. While pro-
cessing, liquid can circulate through the two holes at the bottom of the
generator probe. The top hole should not be immersed in the sample.
Blocking the upper hole could result in liquid being drawn into the
lower motor bearing.
CAUTION: Do not operate the unit 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 variable speed 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.
