Replacing centrifuge tubes
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.
