Centrifuge 5424 / 5424 R — Operating manual
6.2.1 Clean / disinfect device
1. Switch off the device from the mains power switch while the lid is opened and remove the
mains power switch from the power supply.
2. Unscrew the rotor nut by turning it counterclockwise with the rotor key.
3. Remove rotor.
4. Use the agents specified above (see p. 27) to clean and disinfect the device and the rotor
chamber.
5. Wipe all accessible surfaces of the device and the accessories, including the power cable,
with a moist cloth.
6. Thoroughly clean the rubber seals of the rotor chamber with water.
7. Rub the dry rubber seals with glycerine or talcum powder to prevent them from becoming
brittle. Other components of the device, such as the lid latch, motor shaft and rotor cone,
must not be lubricated.
8. Clean the motor shaft with a soft, dry and lint-free cloth.
9. Check device and accessories for corrosion and damage.
6.2.2 Clean / disinfect rotor
1. Clean Rotors, rotor lid and adapter with the aforementioned agents and disinfect them
(see p. 27).
2. Use a bottle brush to clean and disinfect the rotor bores.
3. Rinse Rotors, rotor lid and adapter thoroughly with water. Pay particular attention to the rotor
bores of the fixed-angle rotors.
4. Place rotors and accessories onto a cloth to dry. Place fixed angle rotors with the rotor bores
facing downwards to allow the bores to dry as well.
5. Clean the rotor cone with a soft, dry and lint-free cloth and inspect for damage. Do not
lubricate the rotor cone.
6. Place the dry rotor onto the motor shaft.
7. Tighten the rotor nut firmly by turning it clockwise with the rotor key.
NOTICE!
Damage from UV and other high-energy radiation.
 Do not disinfect by any method based on UV, beta and gamma radiation or other high-energy
radiation.
Hint!
Autoclave
All Rotors, rotor lid and adapter can be autoclaved (121°C, 20 min).
After a maximum of 50 autoclave cycles, replace the lids of the aerosol-tight rotors.
Hint!
Aerosol-tightness
Check that the seals are intact before use.
Replace the rotor lids of aerosol-tight rotors when the sealing rings on the lid screw and in the lid
groove are worn. The sealing rings require regular care to protect the rotors.
Aerosol-tight rotors should never be stored with lids screwed on!
In order to prevent damage, lightly lubricate the lid thread of the aerosol-tight rotors with pivot
grease (order no. Int.: 5810 350.050 / North America: 022634330) on a regular basis.
