41.1.2

Surface disinfection


If infectious materials penetrates into the centrifugal chamber this is to be disinfected immediately.

Ingredients of suitable disinfectants:
ethanol, n-propanol, ethyl hexanol, anionic tensides, corrosion inhibitors.

After using disinfectants, remove the disinfectant residue by wiping with a damp cloth.

The surfaces must be dried immediately after disinfecting.
41.1.3

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.
41.2

Rotors and Attachments

41.2.1

Cleaning and care


In order to avoid corrosion and changes in materials, the rotors and accessories have to be cleaned regularly
with soap or with a mild cleaning agent and a moist cloth. Cleaning is recommended at least once a week.
Contaminants must be removed immediately.

Ingredients of suitable detergents:
soap, anionic tensides, non-ionic tensides.

After using detergents, remove detergent residue by rinsing with water (only outside of the centrifuge) or wipe off
with a damp cloth.

The rotors and accessories must be dried directly after cleaning.

Angle rotors, container and hanger made of aluminium are to be lightly greased after drying using acid-free
grease, e.g. vaseline.

In order to prevent corrosion as a result of moisture between the rotor and the motor shaft, the rotor should be
disassembled and cleaned at least once a month, and the motor shaft should be lightly greased.

The rotors and accessories have to be checked weekly for wear and corrosion. For swing-out rotors, it is
important to check the area of the lifting lugs, for hangers, the grooves and the base should be checked for
cracks.
Example: Crack in the groove area:
Rotors and attachments may no longer be utilised upon indication of wear and tear or corrosion.

Check the firm seating of the rotor on a weekly basis.
41.2.2

Disinfection


If infectious material should get on the rotors or accessories, they must be appropriately disinfected.

Ingredients of suitable disinfectants:
ethanol, n-propanol, ethyl hexanol, anionic tensides, corrosion inhibitors.

After using disinfectants, remove disinfectant residue by rinsing with water (only outside of the centrifuge) or wipe
off with a damp cloth.

The rotors and accessories must be dried directly after disinfection.
