For the other rotors and rotor lids of this centrifuge (see Rotors on p. 18) there is no limit on the service life
as long as the following prerequisites are met: proper use, recommended maintenance and undamaged
condition. To guarantee aerosol tightness, lids of aerosol-tight rotors must be replaced after 50 autoclaving
cycles.

•Proper use,
• Recommended maintenance
• Undamaged condition
The date of manufacture is stamped on the rotors in the format 03/10 (= March 2010) or on the inside of the
plastic rotor lids in the form of a clock . This is for information only and does not have any reference to
the service life.
WARNING! Risk of injury from chemically or mechanically damaged accessories.
Even minor scratches and cracks can lead to serious internal material damage.
Protect all accessory parts from mechanical damage.
Inspect the accessories for damage before each use. Replace any damaged accessories.
Do not use rotors or buckets with signs of corrosion or mechanical damage
(e.g.,deformations).
Do not use any accessories whose maximum service life has been exceeded.
CAUTION! Risk of injury due to chemically damaged rotor lids or caps.
Transparent rotor lids or caps made from PC, PP or PEI may lose their strength under the
impact of organic solvents (e.g., phenol, chloroform).
If rotor lids or caps have come into contact with organic solvents, they should be cleaned
immediately.
Regularly check the rotor lids and caps for damages and cracks.
Immediately replace rotor lids or caps that have cracks or milky stains.
