Rotors and Attachments

24.2.1

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.

The rotors and accessories have to be checked weekly for wear and corrosion.
Rotors and attachments may no longer be utilised upon indication of wear and tear or corrosion.
24.2.2

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.
24.2.3

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.
24.2.4

Rotors and accessories with limited service lives

The use of certain rotors, hangers and accessory parts is limited by time.
These are marked with the maximum permitted number of operating cycles or with an expiration date and the
maximum permitted number of operating cycles or just with the expiration date; e.g.:
- usable until end of month/year: 10/2024 ("usable until end of month/year: 10/2024")
- "max. cycles: 40000" (max. run cycles: 40000)
For safety reasons, rotors, hangers and accessory parts may no longer be used if either the indicated
maximum number of operating cycles or the indicated expiration date has been reached.
The centrifuge is equipped with a cycle counter, which counts the running cycles (centrifugation runs) of the various
rotor codes. For a description, see the "Cycle counter" chapter.
