6.2.2 Cleaning and disinfecting the rotor
1. Inspect the rotor and accessories for damage and corrosion. Do not use any damaged rotors or
accessories.
2. Clean and disinfect the rotors and accessories with the recommended cleaning agents.
3. Use a bottle brush to clean and disinfect the rotor bores.
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. Clean the rotor cone with a soft, dry and lint-free cloth. Do not lubricate the rotor cone.
7. Inspect the rotor cone for damage.
8. Place the dry rotor onto the motor shaft.
9. Tighten the rotor nut firmly by turning it clockwise with the rotor key.
10.Leave the rotor lid open when the rotor is not being used.
6.3 Additional service instructions for Centrifuge 5424 R
Empty and clean the condensation water tray regularly and especially after liquid spillage in the rotor
chamber. Pull out the tray for condensation water from the left side of the centrifuge.
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.
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).
Detailed instructions for cleaning and maintenance can be found in "Fixed-Angle Rotor - Basic
Inspection" and "Swing-Bucket Rotor - Basic Inspection".
Do not immerse the rotor in liquid as liquid can get trapped inside the cavities.
