Maintenance and servicing

Pull the mains plug before cleaning.
Before any other cleaning or decontamination process other than that recommended by the manufacturer is
applied, the user has to check with the manufacturer that the planned process does not damage the device.
•
Cleaning agents and disinfectants which lie in the pH range 5 – 8 are to be utilised. Alkaline cleaning agents with
a pH value > 8 are to be avoided.
•
In order to prevent appearances of corrosion through cleaning agents or disinfectants, the application guide from
the manufacturer of the cleaning agent or disinfectant are absolutely to be heeded.
16.1

Centrifuge

•
Regularly clean the centrifuge housing and the centrifugal chamber; and if necessary, clean with soap or a mild
cleaning agent and water. For one thing, this services purposes of hygiene, and it also prevents corrosion
through adhering impurities.
•
In the event of condensation water formation, dry the centrifugal chamber by wiping out with an absorbent cloth.
•
If infectious materials penetrates into the centrifugal chamber this is to be disinfected immediately. For surface
disinfection we recommend Bacillol Plus from the company Bode Chemicals in Hamburg. After use the
disinfection medium Bacillol Plus must be thoroughly removed with water.
•
Lightly grease the rubber seal of the centrifugal chamber after every cleaning.
16.2

Rotors and Attachments

•
Rotors and accessory parts must be regularly cleaned with soap or a mild cleaning agent and water in order to
prevent corrosion and changes of material. Cleaning is recommended at least once a week, even better after
every usage.
•
If the rotor or accessory parts are contaminated by pathogenic or radioactive material, a suitable cleaning has to
be executed. For disinfection we recommend Helipur H plus N from the company B. Braun Melsungen. For the
removal of radioactive material we recommend deco neutracon from the company Decon Laboratories Limited.
•
The rotors and accessory parts must be dried immediately after cleaning.
•
The rotors and accessory parts are to be checked on a monthly basis for corrosion damage.
Rotors and attachments may no longer be utilised upon indication of wear and tear or corrosion.
