35.1.3

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.

Rotors and Attachments

35.2.1

Cleaning and care

•
In order to prevent corrosion and material changes, rotors and accessories must be cleaned regularly with soap
or a mild detergent and a damp 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 the accessory parts have to be checked on a monthly basis 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.
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.
35.2.2

Disinfection

•
If infectious material should get on the rotors or accessories, they must be appropriately disinfected.
•
Ingredients of suitable disinfectants:
glutaraldehyde, 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.
35.2.3 Removal of radioactive contaminants
•
The agent must be specifically labelled as being an agent for the removal of radioactive contaminants.
•
Ingredients of suitable agents for removing radioactive contaminants:
anionic tensides, non-ionic tensides, polyhydrated ethanol.
•
After removing the radioactive contaminants, remove agent 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 removing the radioactive contaminants.
35.2.4

Trunnions

With swing-out rotors the trunnions must be regularly lubricated (Hettich Lubricating Grease No. 4051) in order to
ensure consistent swinging out of the hangers.
