Operation
Run Procedure
CAUTION
Always run any type of rotor with a balanced load.
7
Close the centrifuge door and push firmly down on both sides of the door front until you hear
a clicking (latching) sound.
8
Remove the rotor from the centrifuge if a long period between runs is anticipated.
CAUTION
If the rotor is left in the centrifuge between runs, make sure the rotor is seated on
the drive shaft and the tie-down screw is tight before each run.
Entering Run Parameters
When the power is applied for the initial use (no previous runs), default values are displayed (see
Figure 2.2 ). After the initial use, the parameters of the latest previous run are displayed when power
is applied.
When run parameters for a rotor have been entered, as described below, they are retained in the
centrifuge memory and can be recalled by simply entering the rotor number. The recalled program
can then be used for the current run or altered as required.
Figure 2.2 Default Parameters
1. Accelerate rotor to 2000 RPM.
2. Continue run for two minutes.
3. Cool chamber to 20°C (refrigerated models only).
4. Use acceleration curve 8.
