Customer Control Inspection
To keep your centrifuge in good working condition and ensure accurate test results, Thermo Fisher
Scientific recommends that you check the speed controls, timer controls and temperature controls at
least twice a year. If the bi-annual inspection reveals inaccurate results for any of these controls, inform
Customer Service to recalibrate the controls.
Speed Controls
1. Prepare a sample of test fluid.
2. Install the rotor in the rotor chamber.
3. Load and balance the rotor according to the instructions in the rotor manual.
4. Close the centrifuge door.
5. Set the run parameters for a commonly used protocol, with speed controlled by rpm, and run
duration set to HOLD.
6. Deselect RCF or SLOW START if indicators are lit.
7. Press the
key.
8. Wait for the speed value in the run display to reach the specified set speed. Wait an additional 5
minutes for speed to stabilize.
9. Check rotor speed through the viewing port in the centrifuge door using a strobe tachometer (in
rpm, following instructions supplied with the tachometer).
The tachometer should indicate rpm equal to the SET value 20 rpm or
% (2000 rpm and
below
rpm, above 2000 rpm
%).
10. If necessary, repeat this procedure at other speeds that are commonly used in your protocols.
Timer Controls
1. Prepare a sample of test fluid.
2. Install the rotor in the rotor chamber.
3. Load and balance the rotor according to the instructions in the rotor manual.
4. Close the centrifuge door.
5. Set the run parameters for a commonly used protocol, but set the run duration by time
(MIN:SEC) to 10:00.
6. Press the
key.
7. Using a stopwatch, begin timing precisely as the run time display counts down to 10:00. Then stop
timing precisely as the RUN TIME display counts down to 00:00.
The stopwatch should read between 9:30 to 10:30, representing 10:00
% (29 seconds).
8. If necessary, repeat this procedure at other speeds that are commonly used in your protocols.
