Translation of the original operating manual
8.1.2
Accessories
For the care of the accessories, special safety measures must be
considered as these are measures that will ensure operational safety
at the same time.
•
Immediately rinse off the rotor, buckets, or accessories under
running water if they have come into contact with any liquids that
may cause corrosion. Use a brush for test tubes to clean the
bores of angle rotors. Turn the rotor upside down and allow it to
dry completely.
•
Clean the accessories outside the centrifuge once a week or
preferably after each use. Rubber cushions should be removed,
cleaned and dried.
•
If the rotors or accessories have been contaminated with toxic,
radioactive, or pathogenic substances, clean them immediately
with a suitable decontamination agent (depending on the type of
contamination). Take suitable precautions for your own safety if
there is a risk of toxic, radioactive, or pathogenic contamination.
•
Dry the accessories with a soft cloth or in a drying chamber at
approx. 50°C.
8.1.2.1
Plastic Accessories
The chemical resistance of plastic decreases with rising temperatures
(e.g. during drying, see Resistance Data in chapter 11 "Appendix").
•
If solvents, acids, or alkaline solutions have been used, clean the
plastic accessories thoroughly.
8.1.2.2
Aluminium Accessories
Especially aluminum parts are susceptible to corrosion.
•
Acid-containing cleaning agents and alkaline cleaning agents
must be avoided.
•
Grease aluminum parts at least once a week with slushing oil for
protection against corrosion (part no. 70104).
This essentially increases their service life and reduces susceptibility
to corrosion.
8.1.3
Rotors
Rotors are produced with highest precision, in order to withstand the
permanent high stress with high gravitational fields.
Chemical reactions as well as stress-corrosion (combination of
oscillating pressure and chemical reaction) can affect or destroy the
metals. Barely detectable cracks on the surface can expand and
weaken the material without any visible signs.
