3.4 PLACEMENT AND OPERATING EQUIPMENT (continued)
Be sure to keep the operating area within the temperatures listed below.
• For QBC Centrifugal Hematology tests: operating temperature should be maintained
at 20 to 32 ºC (68 to 90 ºF) to assure proper cell layering in QBC blood tubes.
• For QBC Malaria Test: operating temperature should be maintained
at 16 to 37 ºC (60 to 99 ºF) to assure the concentration of parasitic organisms.
3.5 ROTOR ASSEMBLY
The QBC Capillary Centrifuge is shipped with
the rotor assembly completely installed.
If the rotor is removed, for example for
cleaning (see Section 9.2), it can be
reinstalled as follows:
a) Position the rotor so that the slots
on the underside of the rotor hub
are aligned with the drive pin in
the motor shaft (Figure 3-4).
b) Press the rotor down until the drive
pin is seated in the hub slots and
3-5 threads of the shaft protrude
above the hub, about 6 mm (¼”).
c) Thread the head nut onto the shaft finger-tight,
by turning it clockwise. Tighten with a light
torque using the head nut wrench supplied with
the centrifuge (Figure 3-5). DO NOT OVERTIGHTEN.
Turn nut 1-2 tube positions to tighten.
CAUTION
TO PREVENT DAMAGE TO ROTOR COVER
AND CENTRIFUGE LID, BE SURE ROTOR
IS CORRECTLY SEATED ON DRIVE PIN.
