Entering the RCF value
You can adjust the RCF set value in steps of 1. The
set value is entered analogously to the speed.
As long as the rotor has not been identified, it is not
possible to display RCF values. This is signaled by
dashes in the display.
Shortly after starting the centrifuge run, the rotor is
identified and the actual value is displayed.
NOTE:
If you select an extremely low RCF value, this may be
automatically corrected if the resulting speed is lower
than 300 rpm.
RCF value explanation
The
r
elative
c
entrifugal
f
orce (RCF) is given in multi-
ples of the earth gravity
g
. It is a unit-free number that
allows the comparison of the efficiency of separation
or sedimentation of diverse instruments, since it is
independent of the instrument used. The only values
entered in the equation are radius and speed of cen-
trifugation:

RCF
11.18
r
r = radius of centrifugation in cm
n = speed in rpm
The maximum RCF value refers to the maximum
radius of the tube bore.
Please note that this value decreases de-
pending on the tubes and adapters used.
You may take this into account when calculating the
RCF value for your application.
