3.5.4 Extreme strain on the centrifuging tubes
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 the use of aggressive chemicals, including strong and weak alkali, strong acids,
solutions with mercury, copper and other heavy metal ions, halogenated hydrocarbons,
concentrated saline solutions and phenol.
 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.
CAUTION! Risk of injury from overloaded tubes.
 Note the loading limits specified by the tube manufacturer.
 Only use tubes which are approved by the manufacturer for the required rcf.
NOTICE! Risk from damaged tubes.
Damaged tubes must not be used, as this could cause further damage to the device and the
accessories and loss of the samples.
 Before use, visually check all of the tubes for damage.
NOTICE! Risk from open tube lids.
Open tube lids can break off during centrifugation and damage both the rotor and the
centrifuge.
 Carefully seal all tube lids before centrifuging.
NOTICE! Hazard to plastic tubes from organic solvents.
The density of plastic tubes is reduced when organic solvents (e.g., phenol, chloroform) are
used, i.e. the tubes could become damaged.
 Note the manufacturer’s information on the chemical resistance of the tubes.
NOTICE! Sample tubes heat up.
In uncooled centrifuges, the temperature in the rotor chamber, rotor and sample can increase
to above 40 °C, based on the run time, g-force (rcf)/speed and ambient temperature.
 Note that this can reduce the centrifugation resistance of the sample tubes.
 Please note the temperature resistance of the samples.
