Das
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 centre.
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. It increases linearly as a function of the
distance with regard to the axis of rotation and quadratically as a function of 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.
2.2.2 Area of application
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 specialised technical applications in the clinical, biological, or
biochemical context:
For numerous clinical examinations, cellular material must be separated from
the liquid to be analysed. 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 c
cream and low-fat milk.
Particularly big centrifuges are used in the sugar industry for separating 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.

2.2.2.1 Speed, radius, and relative centrifugal force
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 x 10-6 x r x n2
r = radius in cm
n = speed in rpm
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 chapter 11.2 - "Speed-gravitational-field-

2.2.2.2 Density
The laboratory centrifuge is suitable for the separation of constituents of different
densities in mixtures with a maximum density of 1.2 g/cm3. All information
concerning the speed of rotors and accessories refers to liquids with a density
corresponding to this specification. If the density is above this value, the maximum
permissible speed of the centrifuge must be reduced based on the following
formula:

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, the
centrifuge will immediately switch off and decelerate brakeless. If the lid is open,
the drive is completely separated from the mains power supply, i.e. the centrifuge
cannot be started (see chapter 7.1.1 - "Emergency lid release").
Opening of the centrifuge lid is only possible if the rotor is at a standstill. This
standstill is checked by the microprocessor.
An internal system check monitors the data transfer and sensor signals with regard
to plausibility. Errors are detected with extreme sensitivity and displayed as error
messages in a dialog box (see chapter 7.2 - "Table of error codes").

Operate the centrifuge only in closed and dry rooms.
All the energy supplied to the centrifuge is converted into heat and emitted to the
ambient air.
Ensure sufficient ventilation.
Keep a safety distance of at least 30 cm around the centrifuge so that the vents
in the centrifuge remain fully effective.
Do not subject the centrifuge to thermal stress, e.g. by positioning it near heat
generators.
Avoid direct sunlight (UV radiation).
The table must be stable and have a solid, even surface.
Attention: During transport from cold to warmer places, condensational water
will collect inside the centrifuge. It is important to allow sufficient time for
drying (min. 24 h) before the centrifuge can be used again.

Sartorius centrifuges are units of protection class I. The centrifuges of this model
series have a three-wire power cord with a fixed cable. They are equipped with a
mains power switch with an integrated thermal circuit breaker.
Switch the unit off by actuating the mains power switch.
If it has tripped, let the circuit breaker cool for approximately 2 minutes.
Switch the unit on.
The centrifuge is now ready for operation.
Typically, the centrifuge must be protected with 16 Amp L or B fuses that are to be
provided by the customer.
