6.2.1 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 seals of the rotor chamber with water.
6. 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.
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.
NOTICE! Corrosion due to aggressive cleaning agents and disinfectants.
Do not use corrosive cleaning agents, aggressive solvents or abrasive polishes.
Do not incubate the accessories in aggressive cleaning agents or disinfectants for longer
periods.
NOTICE! Damage from UV and other high-energy radiation.
Do not use UV, beta, gamma, or any other high-energy radiation for disinfecting.
Avoid storage in areas with strong UV radiation
Autoclaving
All rotors, rotor lids and adapters can be autoclaved (121 °C, 20 min).
Replace the lids of the aerosol-tight rotors after a maximum of 50 autoclaving cycles.
Aerosol tightness
Check that the seals are intact before use.
Replace the rotor lids with screw cap when the sealing rings on the lid screw and in the lid
groove become 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).
