Centrifuges
2-6
2-8. Operation
To perform the run:
1. Set the POWER switch to " I ".
2. Press the DOOR switch to release the chamber door.
3. Install the rotor on the drive spindle and close the chamber
door. When properly closed, the lid latch automatically locks
the door and the
READY indicator light comes on.
4. Set the
SPEED
dial to the desired run speed.
NOTE
Selected run speed is to be verified and adjusted during
the run after the value shown in the SPEED display has
stabilized. Adjust the SPEED dial until the SPEED
display indicates desired run speed (in rpm). If it is not
disturbed, the SPEED dial will retain its position, allowing
for run-to-run repeatability.
5. Turn the TIME dial to the desired run time (the run time, in
minutes, will appear in the
TIME
display); or press the
HOLD
switch to ON for a continuous run and two dashes (--) will
appear in the
TIME display.
6. Press START switch to begin run.
NOTE
If the door is not properly closed, the READY indicator
light will not come on and the rotor will not spin when the
START switch is pressed.
To end a run before the selected run time has elapsed or
to end a run set to HOLD, press the STOP switch.
7. At the end of the run, the DOOR indicator light blinks indicating
that the chamber door can be opened. Press the DOOR switch to
open the chamber door.
Remove the sample from the rotor, close the chamber door, and
set the
POWER switch to " O ".
NOTE
The speed and time values selected at the beginning of
the run are automatically retained unless the power cord
is disconnected from the power source. To do another
run with the same run speed and time parameters:
prepare the rotor, install it in the centrifuge, close the
chamber door, and press the START switch.
W A R N I N G
Be sure the rotor chamber
and chamber door gasket are installed
before the centrifuge run. Operating
the centrifuge without these parts in
place could allow small particles to
exit the rotor chamber in the event of
a rotor failure.

C A U T I O N
Be sure the rotor is prop-
erly balanced and seated on the drive
spindle. All four buckets must be
used on every run (even if empty).
See rotor instruction manual.
