2.2.1 Centrifugation principle
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-
diagram").

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:
n = nmax x

3.3 Responsibility of the operator
The operator is responsible for authorising only qualified personnel to work on the
centrifuge (see chapter 3.4 - "Operating personnel").
The areas of responsibility of the personnel concerning the operation, maintenance,
and care of the unit must be clearly defined.
The safety-conscious work of the personnel in compliance with the operating
manual and the relevant EC and national health and safety regulations as well as
with the accident prevention regulations must be checked at regular intervals (e.g.
every month).
Under the international rules for health and safety at work, the operator is obliged
to:
take measures in order to prevent all danger to life or health during work.
ensure that centrifuges are operated properly and entirely as intended (see
chapter 1.2 - "Intended use").
take protective measures against fire and explosion when working with
hazardous substances.
take measures for the safe opening of centrifuges.

3.6.1 Electrical safety
To reduce the risk of electrical shock, the centrifuge uses a three-wire electrical
cord and plug to connect the equipment to earth-ground. To preserve this safety
feature:
DANGER
Ensure that the wall socket is properly wired and grounded.
Check that the mains voltage agrees with the nominal voltage listed on the
name plate.
Do not place vessels containing liquid on the centrifuge lid or within the safety
distance of 30 cm around the centrifuge. Spilled liquids may get into the
centrifuge and damage electrical or mechanical components.
Work on the power supply system must only be performed by certified
electricians.
Inspect the electrical equipment of the unit regularly. Defects such as loose or
burnt cables must be eliminated immediately.

3.6.2 Mechanical safety
In order to ensure the safe operation of the centrifuge, observe the following:
WARNING
Do not open the lid when the rotor is in motion!
Do not reach into the rotor chamber when the rotor is in motion!
Do not use the centrifuge if it was installed incorrectly.
Do not use the centrifuge without panels.
Do not use the centrifuge if the rotors and inserts show signs of corrosion or
other defects.
Only use the centrifuge with rotors and accessories that have been approved
by the manufacturer. In case of doubt, contact the manufacturer (see chapter
7.3 - "Service contact").
Do not hold your fingers between the lid and the housing when closing the lid.
Risk of crushing!
Defective lid relieving devices could cause the centrifuge lid to fall (contact
the service department, if necessary). Risk of crushing!
Do not hit or move the centrifuge during its operation.
Do not lean against or rest on the centrifuge during its operation.
Do not spin any substances that could damage the material of the rotors and
buckets of the centrifuge in any way. Highly corrosive substances, for example,
damage the material and affect the mechanical strength of the rotors and
buckets.
Stop the centrifuge immediately in the event of a malfunction. Eliminate the
malfunction (see chapter 7 - "Malfunctions and error correction") or inform
the service department of the manufacturer (see chapter 7.3 - "Service
contact").
Ensure that all repairs are performed only by authorised and specialised
personnel.

WARNING
Prior to any start-up, check the centrifuge, rotor, and accessories for signs of
damage that can be discerned from the outside. Special attention must be paid
to all of the rubber parts (e.g. motor cover, lid seal, and adapters) in terms of
visible structural changes. Defective parts must be replaced immediately.
Open the centrifuge when it is not in use so that moisture can evaporate.

3.6.4 Chemical and biological safety
If pathogenic, toxic, or radioactive samples are intended to be used in the
centrifuge, it is in the responsibility of the user to ensure that all necessary safety
regulations, guidelines, precautions, and practices are adhered to accordingly.
DANGER
Infectious, toxic, pathogenic, and radioactive substances may only be used in
special, certified containment systems with a bio-seal in order to prevent the
material from being released.
Take suitable precautions for your own safety if there is a risk of toxic,
radioactive, or pathogenic contamination
Materials that chemically react with each other with a high level of energy are
prohibited.
WARNING
Keep informed about local measures to avoid harmful emissions (depending on
the substances to be centrifuged).
Protective clothing is not required for the operation of the centrifuge.
The materials to be centrifuged may, however, require special safety measures
(e.g. centrifugation of infectious, toxic, radioactive, or pathogenic substances).
