Page 23: Section 7 Limitations Of Procedures
Section 7 LIMITATIONS OF PROCEDURES 7.1 QBC CENTRIFUGAL HEMATOLOGY TESTS QBC tests should be performed at temperatures between 20 and 32 ºC (68 and 90 ºF).* If tubes are run at temperatures below 20 ºC, test results may be erroneously high; if tested above 32 ºC, interfaces may become blurred and difficult to detect visually or automatically, depending on the model of QBC analyzer performing the test. -
Page 24: Section 8 Calibration Checks
Section 8 CALIBRATION CHECKS According to Federal Regulations, centrifuges, such as the QBC Capillary Centrifuge, require verification or calibration as follows: 1) before initial use; 2) after repair or adjustments; and 3) annually after use. The centrifuge timer, however, should be checked for accuracy at least every 3 months. The QBC Capillary Centrifuge has been fully calibrated at the factory and is ready to deliver consistent, accurate test results upon first use. -

Section 9 MAINTENANCE AND SERVICE 9.1 GENERAL CLEANING CAUTION TO AVOID ELECTRICAL HAZARDS, ALWAYS DISCONNECT THE POWER CORD BEFORE CLEANING. Use soap or a mild detergent and water to clean the lid, housing and most parts of the QBC Capillary Centrifuge. (See below for special instructions on cleaning the rotor.) To prevent marring or scratching the finish, avoid solvents or strong abrasives. -
Page 26: Rotor Cleaning Procedures
• Cracks, especially hairline cracks in the region adjacent to the hub; • Surface corrosion, particularly in the region of the hub; • Deep scratches or severe dents. If any of the above defects are found, replace the rotor with a new assembly. See Section 9.6 for catalog numbers. Also inspect the motor shaft, shaft pin and head nut for signs of wear, corrosion or damage. -
Page 27: Releasing Lid Latch
9.3 RELEASING LID LATCH If the lid is latched and there is a loss of main power to the centrifuge – i.e., an interruption of primary electrical power – the lid will remain latched. A jammed plunger in the latch solenoid can also cause the lid to remain latched. -
