5 Rotor Information
Fill Level
5-6 MICRO STAR 17 / 17R VWR
Replace Seals
Follow the steps below:
Lubricate all seals.
Press the smaller V-seal into the groove of the rotor collar (a).
Press the larger C-seal in the outer groove of the rotor body (b).
When loading the rotor, ensure that the rotor lid closes securely.
When the rotor lid is damaged or dulled it needs to be replaced.
Fill Level
The tubes are only to be filled to a level which ensures that the sample is unable to reach the top of the
tube during centrifugation.
Checking the Aerosol-Tightness
The aerosol tightness testing of the rotors and buckets depend on the microbiological test process in
accordance with the EN 61010-2-020 Appendix AA.
Whether or not a rotor is aerosol-tight depends primarily on proper handling.
Check as needed to make sure your rotor is aerosol-tight.
