17.1

Centrifuge (housing, lid and centrifuging chamber)

17.1.1

Surface cleaning and care


Clean the centrifuge housing and the centrifuging chamber regularly, using soap or a mild detergent and a damp
cloth if required. For one thing, this services purposes of hygiene, and it also prevents corrosion through
adhering impurities.

Ingredients of suitable detergents:
soap, anionic tensides, non-ionic tensides.

After using detergents, remove the detergent residue by wiping with a damp cloth.

The surfaces must be dried immediately after cleaning.

In the event of condensation water formation, dry the centrifugal chamber by wiping out with an absorbent cloth.

Lightly rub the rubber seal of the centrifuge chamber with talcum powder or a rubber care product after each
cleaning.

The centrifuging chamber is to be checked for damage once a year.
If damage is found which is relevant to safety, the centrifuge may no longer be put into operation. In this
case, notify Customer Service.
17.1.2

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.
17.1.3

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.
17.2

Rotor and accessories

17.2.1

Cleaning and care


To avoid corrosion and changes to the materials, the rotor and accessories have to be cleaned regularly with
soap or 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 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.
17.2.2

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.
