3.5.4 Extreme strain on the sample tubes
WARNING!
Warning!
Risk of injury from corroded or damaged rotors and buckets.
Even minor scratches and cracks can result in serious internal material damage.
 Protect all parts from mechanical damage.
 When inserting the buckets in the swing-bucket rotor, ensure that they do not scratch it.
 Check accessories regularly.
 Do not use rotors or buckets showing signs of corrosion or mechanical damage (e.g.
deformations).
WARNING!
Warning!
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.
 If the rotor is contaminated by aggressive chemicals, clean it immediately using a neutral
cleaning agent. This applies to the base plates of the rotors in particular.
WARNING!
Warning!
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.
CAUTION!
Caution!
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 commencing concentration, carry out a visual check of all tubes for any damage.
CAUTION!
Caution!
Hazard to plastic tubes from organic solvents.
When using organic solvents (e.g. phenol, chloroform) the density of plastic tubes is reduced, i.e.
the tubes could get damaged.
 Follow the manufacturer's information about the chemical resistance of tubes.
CAUTION!
Caution!
Sample tubes are subject to strong heat.
 Please note the temperature resistance of the sample tubes.
