Centrifuge (housing, lid and centrifuging chamber)

16.1.1

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.
16.1.2

Surface disinfection


If infectious materials penetrates into the centrifugal chamber this is to be disinfected immediately.

Ingredients of suitable disinfectants:
ethanol, n-propanol, isopropyl alcohol, glutardialdehyde, quaternary ammonium compounds.

After using disinfectants, remove the disinfectant residue by wiping with a damp cloth.

The surfaces must be dried immediately after disinfecting.
16.1.3

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.

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:
1. Carefully remove padded shells or sealing ring from the haematocrit rotor.
2. Soak haematocrit rotor, lid and padded shells or sealing ring in cold water, until the blood residues are
completely dissolved.
3. 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.
4. Rinse the components in cold water and dry them.
5. They can now be replaced into the centrifuge.
16.3

Procedure in case of broken haematocrit capillaries

Risk of injury!
Best work with two pairs of gloves worn on top of each other. Wear safety goggles and mask, as glass
splinters could be blown off!
1. Carefully remove lid of haematocrit rotor.
2. Remove larger pieces of broken capillaries using pincers.
3. Remove rotor. Carefully and slowly remove the affected padded shells or the sealing ring with pincers and
exchange them.
4. Clean and disinfect as described above.
