Safety instructions on the device
NOTICE!
Sample tubes heat up.
In uncooled centrifuges the temperature in the rotor chamber, rotor and sample can rise to above
40°C dependent on the run time, g-force (rcf) or speed (rpm) and ambient temperature.
Note that this can reduce the centrifugation resistance of the sample tubes.
Please note the temperature resistance of the samples.
WARNING!
Risk to health due to limited aerosol tightness with incorrect rotor/rotor lid combination.
Aerosol-tight centrifugation is guaranteed only if the rotors and rotor lids intended for this purpose
are used. These are always indicated by the prefix FA.
Always use rotors and rotor lids marked aerosol-tight together for aerosol-tight centrifugation.
Only use aerosol-tight rotor lids in combination with rotors which are marked on the rotor lid.
WARNING!
Risk to health due to limited aerosol tightness in the event of incorrect use.
Autoclaving, mechanical stresses and contamination by chemicals or other aggressive solvents
can impair the aerosol-tightness of the rotors and rotor lid.
Regularly check that the seals of aerosol-tight rotor lids are undamaged.
Only use aerosol-tight rotor lids with undamaged and clean gaskets.
Thinly brush the threads of the rotor lid screw with pivot grease (order no. Int.: 5810 350.050 /
North America: 022634330) after every proper autoclaving (121°C, 20 min.). Do not apply
the pivot grease to the gaskets.
Replace aerosol-tight rotor lids after 50 autoclave cycles.
Aerosol-tight rotors should never be stored with rotor lids screwed on.
