Centrifugation is a process for the separation of heterogeneous mixtures of
substances (suspensions, emulsions, or gas mixtures) into their components. The
mixture of substances, which rotates on a circular path, is subject to centripetal
acceleration that is several times greater than the gravitational acceleration.
Centrifuges use the mass inertia inside the rotor chamber for separating the
substances. Due to their higher inertia, particles or media with a higher density travel
outwards. In doing so, they displace the components with a lower density, which in
turn travel towards the center.
The centripetal acceleration of an object inside a centrifuge, as the effect of
centripetal force, depends on the distance between the object and the axis of
rotation as well as on the angular velocity. The bigger the radius in the rotor chamber
is and the higher the speed is, the higher the centripetal acceleration is. However, the
forces acting on the rotor also increase.

Principle

Layout and Mode of Operation 11
Depending on the area of application of the centrifuge and also on the particle size,
solids content and volume throughput of the mixture of substances that is to be
centrifuged, there are different types of centrifuges.
The areas of application go from household use as a salad spinner or honey separator
up to specialized technical applications in the clinical, biological or biochemical
context:
− For numerous clinical examinations, cellular material must be separated from the
liquid to be analyzed. The normal separation process can be sped up considerably
by using laboratory centrifuges.
− In the metal-working industry, centrifuges are used for separating oil from metal
cuttings. Dairies use centrifuges in order to separate cow’s milk into cream and
low-fat milk.
− Particularly big centrifuges are used in the sugar industry.
They are used to separate the syrup from the crystalline sugar.
− Ultracentrifuges are predominantly used in biology and biochemistry in order to
isolate particles, e.g. viruses. They are specifically designed for high speeds up to
500,000 rpm. The rotor moves in a vacuum in order to avoid air friction.
The acceleration g, which the samples are subject to, can be increased by increasing
the radius in the rotor chamber and by increasing the speed. These three parameters
are interdependent and linked with each other via the following formula.
Relative centrifugal force RCF = 11.18 +10–6 +r +n2
r = radius in cm
n = speed in min–1
RCF without any dimension
If two values are entered, the third value is determined by way of the stated formula.
If, afterwards, the speed or the radius is changed, the resulting relative centrifugal
force will be recalculated automatically by the control unit. If the RCF is changed,
thespeed will be adapted while the specified radius is maintained.
The speed-gravitational-field diagram provides an overview of the relationship
between speed, radius and RCF (see tchapter 10.8 “Speed-gravitational-field
diagram”).
The information concerning the speed of rotors and accessories refers to liquids with
a density that is lower than 1.2 g/cm3. If the density is above this value, the maximum
permissible speed of the centrifuge is reduced based on the following formula:
n = nmax +1.2/Rho
Rho = density in g/cm3

Chemical influences have a strong effect on the polymeric chains of plastics, and,
therefore, on their physical properties. Plastic parts can be damaged if solvents, acids
or alkaline solutions are used.
Refer to the resistance data (see tchapter 10.10 “Resistance Data”)!
The rotors and accessories have a limited service life.
– Perform regular checks (at least once per month) for safety reasons!
– Pay special attention to changes, such as corrosion, cracks, material abrasion,
etc.
– After 10 years, they must be inspected by the manufacturer.
– After 50,000 cycles, the rotor must be scrapped for reasons of safety.
– If other data concerning the service life are engraved on the rotor or bucket,
these data shall apply accordingly. For example, a bucket with the engraving
“max. cycles = 10,000” has a service life of 10,000 cycles, and a rotor with
the engraving “Exp. date 02/15” must be scrapped in February 2015 at the
latest (see figure).
Fig. 4: Different service life – engraving on the bucket| rotor
Refer to the table of rotors and accessories with a different service life
(see tchapter 10.9 “Table of Rotors and Accessories with a Different Service
Life”)!
The centrifuge can only be started when the lid is properly closed. The electrical lock
must be locked. The lid can only be opened when the rotor has stopped. If the lid is
opened by way of the emergency release system during operation (see tchapter
7.1.1 “Emergency Lid Release”), the centrifuge will immediately switch off and
decelerate brakelessly. If the lid is open, the drive is completely separated from the
mains power supply, i.e. the centrifuge cannot be started.
