Centrifuge (housing, lid and centrifuging chamber)

23.1.1

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.
23.1.2

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.
23.1.3

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.
23.2

Cleaning and disinfecting the haematocrit rotor

If despite all precautions a leakage of haematocrit capillaries during centrifugation should occur, rotor and lid must be
cleaned according to the following instructions:

Carefully remove padded shells or sealing ring from the haematocrit rotor.

Soak haematocrit rotor, lid and padded shells or sealing ring in cold water, until the blood residues are
completely dissolved.

Perform a suitable disinfection. The application of disinfection substances on the lid is to be avoided as the
inscription can dissolve.
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.

Rinse the components in cold water and dry them.

They can now be replaced into the centrifuge.
