3.5.3 Incorrect handling of the rotors
WARNING! Risk of injury from improperly attached rotors and rotor lids.
 Only centrifuge with rotor and rotor lid firmly tightened.
 If unusual noises occur when the centrifuge starts, the rotor or the rotor lid may not be
properly secured. Immediately press the start/stop key to stop centrifuging.
CAUTION! Risk of injury due to asymmetric loading of a rotor.
 Load rotors symmetrically with identical tubes or plates and buckets.
 Only load adapters with suitable tubes or plates.
 Always use tubes or plates of the same type (weight, material/density and volume).
 Check that loading is symmetrical by balancing the adapters and tubes or plates used with
scales.
The device automatically detects imbalances during operation and stops the run immediately
with an error message and a signal tone. Check the loading, balance the tubes and re-start the
centrifugation.
CAUTION! Risk of injury from overloaded rotor.
The Centrifuge 5430/5430 R is designed for the centrifugation of material with a max. density
of 1.2 g/mL at maximum speed and filling volume and/or load.
 Do not exceed the maximum load of the rotor.
NOTICE! Damage to rotors from aggressive chemicals.
Rotors are high-quality components which withstand extreme stresses. This stability can be
impaired by aggressive chemicals.
 Avoid using aggressive chemicals, including strong and weak alkalis, strong acids,
solutions with mercury, copper and other heavy metal ions, halogenated hydrocarbons,
concentrated saline solutions and phenol.
 If the rotor is contaminated by aggressive chemicals, clean it immediately using a neutral
cleaning agent. This applies to the rotor bores, in particular.
 Due to the manufacturing process, color variations may occur on rotors marked "coated".
These color variations do not effect service life or resistance to chemicals.
NOTICE! If handled incorrectly, the rotor can fall over.
The rotor can fall over if the buckets are used as a handle.
 Remove the buckets before inserting and/or removing a swing-bucket rotor.
 Always use both hands to carry the rotor cross.
CAUTION! Risk of injury due to chemically damaged rotor lids or caps.
Transparent rotor lids or caps made from PC, PP or PEI may lose their strength under the
impact of organic solvents (e.g., phenol, chloroform).
 If rotor lids or caps have come into contact with organic solvents, they should be cleaned
immediately.
 Regularly check the rotor lids and caps for damages and cracks.
 Immediately replace rotor lids or caps that have cracks or milky stains.
