Drucker Diagnostics QBC Horizon 755VES Centrifuge (120V, 60Hz) - Manual (Page 21)

6.4 CENTRIFUGATION INSTRUCTIONS
6.4.1 Affixing Identification Labels
(QBC Malaria Test Only)
Before Placing QBC Malaria Test tubes on the
centrifuge rotor, a correctly marked patient
identification label should be affixed on each
tube between the two white lines scribed
near one end of the tube (Figure 6-1).
6.4.2 Loading and Balancing Rotor
Position QBC specimen tubes in the holder slots of the rotor, with the stopper against the outer rim of the rotor.
Arrange the tubes in a balanced array, i.e., #2 tube opposite #1 tube, #4 opposite #3, etc. When centrifuging an
odd number of tubes, balance the rotor with an empty QBC hematology tube or QBC Malaria Test tube. Note:
Do not attempt to re-use the balance tube for patient samples.
6.4.3 Centrifugation Procedures
a) Secure the cover to the rotor; then close and firmly latch the lid.
b) Press and release the ON button to start the spin cycle.
c) After the five-min spin cycle is complete and the lid pops up, open the lid and REMOVE THE TUBES.
IMPORTANT: Failure to remove tubes promptly after centrifugation may affect cell layer boundaries and
subsequent test results.
d) If not read promptly, the centrifuged tube should be stored temporarily, stopper or closure end down, in
the QBC work station.
Note: See Test Timing in 6.4.4.
CAUTION
DO NOT USE THIS CENTRIFUGE FOR SPINNING MICROHEMATOCRIT OR OTHER
CAPILLARY TUBES. THE ROTOR AND COVER ARE DESIGNED TO ACCOMMODATE
ONLY QBC TUBES. OTHER TYPES OF CAPILLARIES MAY BREAK, CAUSING BLOOD
SPILLS AND LOSS OF SPECIMEN.
