41.2.2
Disinfection
•
If infectious material should get on the rotors or accessories, they must be appropriately disinfected.
•
Ingredients of suitable disinfectants:
ethanol, n-propanol, ethyl hexanol, anionic tensides, corrosion inhibitors.
•
After using disinfectants, remove disinfectant 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 disinfection.
41.2.3
Removal of radioactive contaminants
•
The agent must be specifically labelled as being an agent for the removal of radioactive contaminants.
•
Ingredients of suitable agents for removing radioactive contaminants:
anionic tensides, non-ionic tensides, polyhydrated ethanol.
•
After removing the radioactive contaminants, remove agent 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 removing the radioactive contaminants.
41.2.4
Trunnions
With swing-out rotors the trunnions must be regularly lubricated (Hettich Lubricating Grease No. 4051) in order to
ensure consistent swinging out of the hangers.
41.2.5
Rotors and accessories with limited service lives
The use of certain rotors, hangers and accessory parts is limited by time.
These are marked with the maximum permitted number of operating cycles or with an expiration date and the
maximum permitted number of operating cycles or just with the expiration date; e.g.:
- "einsetzbar bis Ende: Ι V. Quartal 2011 / usable until end of: Ι V. Quarter 2011" or
"einsetzbar bis Ende Monat/Jahr: 10/2011 / usable until end of month/year: 10/2011"
- "Max. Lauf Zyklen / max. cycles: 40000".
For safety reasons, rotors, hangers and accessory parts may no longer be used if either the indicated
maximum number of operating cycles or the indicated expiration date has been reached.
41.2.6
Calculation of the number of run cycles carried out
To calculate the number of carried out run cycles (centrifugation runs), the run-time per centrifugation run and the
operating hours of the device are required.
To query the operating hours, see the chapter "Operating hours query".
If centrifugation runs were carried out with different run-times, the shortest run-time is to be used for the calculation.
The number of carried out run cycles (centrifugation runs) are calculated as follows:
Number of executed running cycles = operating hours [h] x 60 ÷ run-time [min]
e.g.: Operating hours 2000 h, run-time 5 min
Number of executed running cycles = 2000 x 60 ÷ 5 = 24000
