Surface disinfection


If infectious materials penetrates into the centrifugal chamber this is to be disinfected immediately.

Ingredients of suitable disinfectants:
ethanol, n-propanol, isopropyl alcohol, glutardialdehyde, quaternary ammonium compounds.

After using disinfectants, remove the disinfectant residue by wiping with a damp cloth.

The surfaces must be dried immediately after disinfecting.
16.1.3

Removal of radioactive contaminants


The agent must be specifically labelled as being an agent for removing radioactive contaminants.

Ingredients of suitable agents for removing radioactive contaminants:
anionic tensides, non-ionic tensides, polyhydrated ethanol.

After removing the radioactive contaminants, remove the agent residue by wiping with a damp cloth.

The surfaces must be dried directly after removing the radioactive contaminants.
16.2

Rotor and accessories

For safety reasons, the rotor may not be dismantled.


soap or a mild cleaning agent and a moist cloth. Cleaning is recommended at least once a week. Contaminants
must be removed immediately.

If the rotor or accessories are contaminated by pathogenic or radioactive material, appropriate cleaning must be
carried out.

Ingredients of suitable detergents:
soap, anionic tensides, non-ionic tensides.

Ingredients of suitable disinfectants:
glutaraldehyde, propanol, ethyl hexanol, anionic tensides, corrosion inhibitors.

Ingredients of suitable agents for removing radioactive contaminants:
anionic tensides, non-ionic tensides, polyhydrated ethanol.

The rotor and accessories have to be dried immediately after cleaning.

The rotor and accessories have to be checked monthly for wear and tear and damage due to corrosion.
The rotor and accessories must no longer be used if they show signs of wear or corrosion.

Check the firm seating of the rotor on a weekly basis.
16.3

Autoclaving

16.4

Centrifuge containers


With leakiness or after the breakage of centrifuging containers broken container parts and leaked centrifugation
material are to be completely removed.

The rubber inserts as well as the plastic sleeves of the rotors are to be replaced after a glass breakage.
Remaining glass splitters cause further glass breakage!

If this concerns infectious material, a disinfection process is to be executed immediately.
