Cleaning

Clean rotor and accessories as follows:
• Use warm water with a neutral solvent.
• Never use caustic cleaning agents such as soap suds, phosphoric acid, bleaching solutions or
scrubbing powder.
• Rinse the cavities out thoroughly.
• Use a soft brush without metal bristles to remove stubborn residue.
• Afterwards rinse with distilled water.
• Place the rotors on a plastic grate with their cavities pointing down.
• If drying boxes are used, the temperature must never exceed 50 °C, since higher temperatures could
damage the material and shorten the lifetime of the parts.
• Use only disinfectants with a pH of 6-8.
• Dry aluminum parts off with a soft cloth.
Clean centrifuge and accessories as follows:
1. Open the centrifuge.
2. Turn off the centrifuge.
