3. Ramp-down takes place with the selected brake level after the time
has elapsed or if the centrifugation run is cancelled.
🡆 The brake level is displayed.
An audible signal sounds when the rotor comes to a standstill.
‘OPEN’
‘OEFFNEN’
is displayed.
The right side of the
[STOP/OPEN]
button lights up when the
centrifuge is in ramp-down.
The left side of the
[STOP/OPEN]
button lights up when the rotor is
at a standstill.
The light on the
[START/IMPULS]
button and the right side of the
[STOP/OPEN]
button go out.

Short-term centrifugation
Personnel:

Trained user
1. Press and hold the
[START/IMPULS]
button.
🡆 The
[START/IMPULS]
button lights up during the centrifugation
run.
Timing starts at 00:00.
The rotor speed or the RCF value, the temperature in the centri-
fuging chamber (only for centrifuges with cooling) and the elapsed
time are displayed during the centrifugation run.
2. Release the
[START/IMPULSE]
button to end the centrifugation run.
🡆 Ramp-down takes place with the set brake level. The brake level is
displayed.
An audible signal sounds when the rotor comes to a standstill.
‘OPEN’
‘OEFFNEN’
is displayed.

Quick stop function
Personnel:
â– Trained user
Press the
[STOP/OPEN]
button twice.
🡆
Ramp-down with brake level "9" (shortest ramp-down time) is dis-
played and executed.

7.1 Centrifugation parameters
7.1.1 Relative centrifugal force, RCF
The relative centrifugal force RCF is dependent on the speed and the centri-
fuging radius.
The relative centrifugal force RCF is stated as a multiple of the acceleration
due to gravity (g).
The relative centrifugal force RCF is a dimensionless numerical value and is
used to compare the separation and sedimentation performance.
