4. Rinse the rotors and accessories thoroughly with distilled water. Rinse the rotor bores of fixed-angle
rotors particularly thoroughly.
5. Place rotors and accessories on a cloth to dry. Place fixed-angle rotors with the rotor bores facing
downwards to allow the bores to also dry.
6. Correctly reinsert the rotor lid sealing ring in the clean and dry groove.
7. Clean the rotor cone with a soft, dry and lint-free cloth. Do not lubricate the rotor cone.
8. Inspect the rotor cone for damage.
9. Place the dry rotor onto the motor shaft.
10. Tighten the rotor nut firmly by turning it clockwise with the rotor key.
11. Leave the rotor lid open when the rotor is not being used.
6.3 Additional service instructions for Centrifuge 5427 R
 Empty and clean the condensation water tray regularly and especially after liquid spillage in the rotor
chamber.
 Regularly free the rotor chamber ice formations via thawing, by leaving the centrifuge lid open or
carrying out a short temperature control run at approx. 30
°C.
 Leave the centrifuge lid open when not in use for a long period.
Residual moisture can escape. The lid spring is relieved.
 Wipe up condensate in the rotor chamber using a soft, absorbent cloth.
 Remove dust deposits from the ventilation slits of the centrifuge using a brush or swab at the latest
every six months. First switch off the device and remove the power plug.
6.4 Glass breakage
When using glass tubes there is a risk of glass breakage in the rotor chamber. The resulting glass splinters
are swirled around in the rotor chamber during centrifugation and have a sandblasting effect on the rotor
and accessories. The smallest glass particles become lodged in the rubber parts (e.g., the motor guide, the
rotor chamber seal, and the rubber mats of adapters).
Effects of glass breakage in the rotor chamber:
• Fine black metal abrasion in the rotor chamber (in metal rotor chambers)
• The surfaces of the rotor chamber and accessories are scratched.
• The chemical resistance of the rotor chamber is reduced.
• Contamination of samples
• Wear on rubber parts
Do not immerse the rotor in liquid as liquid can get trapped inside the cavities.
NOTICE! Glass breakage in the rotor chamber
Glass tubes in the rotor chamber may break if the g-force is too high. Broken glass can
damage the rotor, accessories and samples.
 Please note the manufacturer's information on the recommended centrifugation
parameters (load and speed).
