11. Disinfection and cleaning
Rotor and accessories must be cleaned once a week to avoid corrosion and changes to
material.
Attention! Disconnect the centrifuge from mains power supply, remove rotor,
and clean it separately. Before any cleaning or decontamination process other than
that is recommended by the manufacturer, the user must ask the manufacturer if
the planned process does not damage the device.
The rotor, rotor chamber, and the outside of the centrifuge should be cleaned with a soaked
gauze or soft cloth. For cleaning, water with soap or other water-soluble mild detergent shall
be used. To disinfect use an alcohol-based disinfectant (70% isopropanol/water mixture). If
corrosive, toxic or radioactive liquids or pathogenic bacteria are spilled in the rotor or its
chamber, the centrifuge must be decontaminated thoroughly.
Rotors are high-quality assemblies which withstand extreme stresses. This stability can be
impaired by aggressive chemicals. Aggressive chemicals can cause corrosion potentially
breaking them and damaging the inside parts, leading to electrical failure.
Damage from UV radiation:
Protective coating of the centrifuge protects it from the sun’s harmful UV rays.
However, do not use beta, gamma, or any other high-energy radiation for disinfection.
