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.
Haematocrit rotor, rotor lid, padded shells, and sealing rings are not autoclavable.
16.1

Cleaning the 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.

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. 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 application of disinfection substances on the lid is to be avoided as the inscription can
dissolve.
4. Rinse the components in cold water and dry them.
5. They can now be replaced into the centrifuge.
