Centrifuge 5804/5804 R/5810/5810 R — Operating manual
7.3.1 Cleaning and disinfecting the device
1. Open the lid. Switch off the device with the mains/power switch. Disconnect the power plug
from the power supply.
2. Loosen the rotor nut by turning the rotor key counterclockwise.
3. Remove the rotor.
4. Clean and disinfect all accessible surfaces of the device, including the power cable, using a
damp cloth and the recommended cleaning agents.
5. Thoroughly clean the rubber seal of the rotor chamber with water.
6. Rub the dry rubber seal with glycerine or talcum powder to prevent it from becoming brittle.
Other components of the device, such as the lid latch, lid springs, motor shaft and rotor cone,
must not be lubricated.
7. Clean the motor shaft with a soft, dry and lint-free cloth. Do not lubricate the motor shaft.
8. Check the motor shaft for damage.
9. Inspect the device for corrosion and damage.
10. Leave the centrifuge lid open when the device is not being used.
11. Only connect the device to the power supply if it is fully dry inside and out.
7.3.2 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. Load the fixed-angle rotor with the cleaned adapters or the swing-bucket rotor with the
cleaned buckets and adapters, if necessary.
11. Leave the rotor lid open when the rotor is not being used.
Hint!
Swing-bucket rotor
• Before cleaning the rotor, remove old pivot grease from grooves and pivots.
• Make sure that the grooves and pivots are clean. Dirty grooves and pivots prevent carriers
from swinging out evenly.
• After cleaning, lubricate the pivots of the rotor and the grooves of the buckets with pivot
grease (order no. Int.: 5810 350.050/North America: 022634330) so that the carriers can
move freely in a swinging manner.
Hint!
After every 200 runs, the centrifuge displays clean rotor three times to remind you about the
regular rotor cleaning.
Hint!
Do not immerse the rotor in liquid as liquid can get trapped inside the cavities.
