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, 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.
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

Rotors and Attachments

23.2.1

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.
•
In the case of biosafety systems (for further details of available biosafety systems see chapter
"Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories"), the packing rings must be checked and
cleaned regularly (weekly).The sealing ring is to be replaced immediately upon indication of crack formation,
embrittlement or abrasive wear. In order to prevent the packing ring from twisting when opening and closing the
cover, the packing ring must be lightly rubbed with talcum powder or a rubber care product.
•
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 accessories have to be checked monthly for wear and tear and damage due to corrosion.
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.
