Troubleshooting
Replacing centrifuge tubes
■ The maximum permissible number of run cycles or the expiry date can
be seen marked on the accessories.
CAUTION
Risk of injury from broken glass.
Broken glass may cause glass splinters and contaminated
liquids to be found inside the centrifuge.
− Wear cut-resistant gloves.
−
Wear protective goggles and a face mask.
Broken parts of the tube, glass splinters and spilled centrifuge material
must be removed completely in the event of leakage or if a centrifuge
tube breaks. Glass splinters that are not removed will cause further glass
breakage.
The rubber inserts and the plastic sleeves of the rotors must be replaced
after a glass breakage.
Disinfection must be carried out if the material is infectious.
