Extreme strain on the sample tubes
CAUTION!
Risk of injury from overloaded rotor.
The device is designed for the concentration of substances with a max. density of 1.2 g/mL at
maximum speed and filling volume and/or load.
Note the maximum payload for each rotor (adapter, tube and content) per rotor bore and/or
per bucket and make sure it is not exceeded.
CAUTION!
Risk of injury from chemically or mechanically damaged accessories.
Even small scratches and cracks can lead to serious internal material damage.
Protect all parts from mechanical damage.
Check accessories regularly.
Do not use rotors or buckets with signs of corrosion or mechanical damage (e.g.
deformations).
Do not use accessories whose maximum service life has been exceeded.
When inserting the buckets and rotors, ensure that they do not become scratched.
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 alkalis, strong acids,
solutions with mercury, copper and other heavy metal ions, halogenated hydrocarbons,
concentrated saline solutions and phenol.
If the rotor is contaminated with aggressive chemicals, clean it immediately using a neutral
cleaning agent and then rinse it thoroughly with water. This applies to the base plates of the
rotors in particular.
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, carry out a visual check of all tubes for any damage.
NOTICE!
Hazard to plastic tubes from organic solvents.
When using organic solvents (e.g. phenol, chloroform) the strength of plastic tubes is reduced,
i.e., the tubes could get damaged.
Follow the manufacturer's information about the chemical resistance of tubes.
NOTICE!
Sample tubes are subject to strong heat.
Please note the temperature resistance of the sample tubes.
