5.4 Centrifuging
Before using the Centrifuge 5418 / 5418 R for the first time, familiarize yourself with the operating controls
and the display (see Overview of operating controls on p. 19).
Each of the centrifuging variants described here must be preceded by the preparation described above (see
Preparing for centrifugation on p. 20).
Only 5418 R: Please also note the instructions on cooling (see p. 22).
5.4.1 Centrifugation with time setting
Perform the following steps in the sequence described.
1. Use time to set the run time.
2. Only 5418 R: Use temp to set the temperature.
3. Use speed to set the g-force (rcf) or speed (rpm).
4. Press start/stop to start centrifuging.
During centrifugation:
• In the display flashes while the rotor is running.
• Only 5418 R: The current temperature will be displayed.
• The fast temp (only 5418 R), open and short keys are blocked during centrifugation.
• During the run you can modify the total run time, the temperature (only 5418 R), the speed and the
rpm/rcf display.
Only 5418 R: To change the centrifugation parameters, press the short key first.
The values flash in the display during the change. The new parameters are adopted immediately.
When the time is changed during a run, the time which has already elapsed is taken into account.
Please note that the shortest new total run time that can be set is the elapsed time plus 2 minutes.
• You can also terminate the centrifugation before the set run time has elapsed by pressing the start/
stop key.
CAUTION! Risk from incorrectly-loaded rotors and damaged/overloaded tubes!
 Before commencing centrifugation, follow the safety instructions relating to risks from
asymmetrically loaded and/or overloaded rotors and from overloaded, damaged and/or
open tubes (see
Warnings for intended use on p. 12).
WARNING! Risk of injury from improperly attached rotors and rotor lids.
 Only centrifuge with rotor and rotor lid firmly tightened.
 If unusual noises occur when the centrifuge starts, the rotor or the rotor lid may not be
properly secured. Immediately press the start/stop key to stop centrifuging.
