Decontamination
Dec
o
ntaminate the centrifuge immediately whenever radioactive material has spilled during
centrifugation.
For general radioactive decontamination use a solution of equal parts of 70
% ethanol, 10
% SDS
and water.
1. Open the centrifuge.
2. Turn off the centrifuge.
3. Pull out the power supply plug.
4. Grasp the rotor with both hands and lift it vertically off the centrifuge spindle.
5. Remove the centrifuge tubes and adaptors and dispose of them or disinfect them.
6. Rinse the rotor first with ethanol and then with de-ionized water.
•
Adhere strictly to the given application times.
7.
Be sure the decontamination solution can drain off the rotor.
8.
Rinse the rotor and accessories thoroughly with water.
9.
Dispose of the decontamination solution according to the applicable guidelines.
10.
Dry all of the rotors and accessorie
s
after cleaning with a cloth or in a warm air cabinet at
a
maximum temperature of 50
°C.
11.
After cleaning, treat the entire surface of aluminum parts with corrosion protection oil
(70009824). Also treat the cavities with oil.
Autoclaving
1. Before autoclaving clean rotor and accessories and described above.
2. Place the rotor on a flat surface.
•
Rotors and adapter can be autoclaved at 121
°C.
•
The maximum permissible autoclave cycle is 20 minutes at 121
°C.
WARNING
Infectious material can get into the centrifuge when a tube breaks or as a
result of spills. Keep in mind the risk of infection when touching the rotor and take all
necessary precautions.
In case of contamination, make sure that others are not put at risk.
Decontaminate the affected parts immediately.
Take other precautions if need be.
CAUTION
Before using any cleaning or decontamination methods except those
recommended by the manufacturer, users should check with the manufacturer that the
proposed method will not damage the equipment.
Note
No chemical additives are permitted in the steam.
