Product description
Centrifuge 5424/5424 R
English (EN)
For the rotors and rotor lids labeled coated, color fluctuations may occur as a result of the production
process. These fluctuations have no effect on service life or resistance to chemicals.
3.4.1 Rcf display and calculation
To determine the g-force (rcf) for a specific adapter, you can calculate per DIN 58 970 using the following
formula:
rcf = 1.118 · 10
-5
· n
2
· r
max
n: revolutions per minute (rpm)
r
max
: max. centrifuging radius in cm
Example
In rotor FA-45-24-11, the 0.5 mL adapter has a maximum radius of 7.3 cm. At 7,000 rpm a maximum
g-force of 4,000 x g is reached.
Use the rpm/rcf key to switch the display of centrifugation speed between speed (rpm)
and g-force (rcf). Ensure that the g-force displayed upon switching is standardized to
suit the rotor FA-45-24-11 without an adapter. When other rotors and adapters are
used, you can achieve the following maximum g-forces (rcf) ) at the maximum speed
(see p. 18):
