2 OPERATION
2.1 Installation of rotors
2.1.1 Mounting and loading angle rotors
Clean the motor shaft as well as the rotor mounting boring with a clean, grease-free piece of
cloth. Place the rotor onto the motor shaft, ensuring that the cross pin aligns correctly with
the rotor slot (see photos 1 and 2).
A partially loaded rotor may be used (ie an 8 place rotor with 2 or 4
tubes loaded). The load must be balanced and the tubes must be
opposite each other. See image below.
Photo 4: Incorrect Photo 5: Correct
Hold the rotor with one hand and secure the rotor to the shaft by turning the rotor nut
clockwise. Tighten rotor nut.

2 OPERATION
2.1.2 Mounting and loading swing out rotors
Clean the motor shaft, as well as the shaft hole in the rotor with a clean and grease-
free cloth. Place the rotor on the motor shaft, taking care that the cross pin is sitting in
the rotor slot (photo 1 and photo 2). Hold the rotor with one hand and secure the rotor
to the shaft by turning the rotor nut clockwise. Tighten rotor nut by hand.
The loading of the buckets and the adapters must be done appropriately so that the
load is balanced with tubes in opposing tube holders. Tubes must be filled evenly by
eye. Weight difference of loaded tubes should not exceed 1g.
2.1.3 Overloading of rotors:
The maximum load permitted for a rotor, which is determined by the manufacturer, as
well as the maximum speed allowed for thie rotor (see label on rotor), must not be
exceeded. Liquids to be centrifuged should have an average homogeneous density
of 1.2 g/ml or less when the rotor is spinning at maximum speed. In order to centri-
fuge liquids with a higher density, the speed must be reduced according to the follow-
ing formula:
Reduced speed n = x max. speed (nmax) of the rotor
Example
nred = x 4,000 = 3,360rpm
If in doubt, contact the manufacturer!
2.1.4 Removing the rotor
Hold the rotor with one hand. Loosen the rotor nut byturning it conterclockwise.
ATTENTION:
Do not operate the centrifuge with rotors which show any signs of corrosion
or mechanical damage.
Do not centrifuge extremely corrosive substances which could damage the
rotor.

2 OPERATION
2.2.5 Nomogram – to convert Speed into RCF-value
CHART
to determine the relative centrifugal force (RCF-value).
This value is the multiplier to the gravitational pull of earth (g).
Example:
Measure the distance in mm from the center of the rotor (radius) to the most outer part (bottom of
the tube) in the used bucket, tube rack or rotor . Set your ruler in the “radius” column to the
corresponding radius. Position the left part of your ruler to the desired speed and read off the
according RCF-values. When you know the required RCF-value, you can determine the correct
speed.
The correct value is based on the following formula:
RCF= 11.18 x r x ( )
2
RCF = Relative centrifugal force (multiplier to the gravitational pull of the earth)
r = radius in cm

3 MAINTENANCE
3.1 Service and maintenance
3.1.1 Maintenance and cleaning
Maintenance:
Maintenance of the centrifuge is confined to keeping the rotor, the rotor chamber and
the rotor accessories clean as well as to regularly lubricating the rotor insert bolts of a
swing out rotor (if available). Vaseline, readily available, is the most suitable lubricant.
The Vaseline must be free of resin and acids. Lubricants containing molycote and
graphite are not allowed.
Please pay special attention to anodized aluminium parts. Breakage of rotors can be
caused even by the slightest damage.
If rotors, buckets or tube racks come in contact with corrosive substances, they
must be cleaned carefully and immediately. Corrosive substances include:
• Alkalis
• Alkaline soap solutions
• Alkaline amines
• Concentrated acids
• Solutions containing heavy metals
• Water-free chlorinated solvents
• Saline solutions, e.g. salt water
Cleaning:
Thorough cleaning not only has its purpose in hygiene but also in avoiding corrosion.
In order to avoid damaging anodized parts such as rotors, reduction plates etc., only
pH-neutral detergents with a pH-value of 6-8 may be used for cleaning. Alkaline
cleaning agents (pH-value > 8) must not be used.
After cleaning, please ensure all parts are dried thoroughly, either by hand or in a hot-
air cabinet (max. temperature + 50°C).
Due to humidity and not hermetically sealed samples, condensate may be formed.
The condensate must to be removed regularly from the rotor chamber with a soft
cloth.
The maintenance cleaning procedure must be repeated every 10 to 15 runs or
at least once a week.
3.1.2 Glass breakage
With high g-values, the rate of glass tube breakage increases. Glass splinters have to
be removed immediately from rotor, buckets, adapters and the rotor chamber itself.
Fine glass splinters will scratch and therefore damage the protective surface coating
of a rotor.
If glass splinters remain in the rotor chamber, fine metal dust will build up due to air
circulation. This very fine, black metal dust will contaminate the rotor chamber, the
rotor, the buckets and the samples.

4 TROUBLE SHOOTING
4.2.2 Description of the error message system
Error messages are shown in the “SPEED” display (see photo 17).
There are two different kinds of errors.
• Errors No. 1 – 49 (forced stop)
If one of these errors occur, the rotor decelerates from preset speed down to 0. As
soon as the rotor stops, the error message can be reset by opening and closing the
lid of the centrifuge.
• Errors No. 50 – 99 (emergency stop)
If one of these errors occur, the frequency converter switches off. The rotor will stop
without the brakes being applied, To reset the error, the centrifuge must be un-
plugged and then plugged in again.
In case the unit stops due to an error indication, you should restart the unit to check
whether the error occurs again.
The error message figures not listed in this chapter are currently not in use. They are
reserved for future use in completing the error message recognition program
