The referenced original device seems to be not supported any more and spare parts seem not to be available any more.
The only issue of this otherwise perfectly maintained and working device was a broken handle (see attached images).
I got access to it and was able to design a spare that fits well. A Service Technician for the device even approved it and cleared the device again for operation.
The steel axis and two nook-thingies are being reused to fix the handle to that chamber door, exactly as it was before. The handle is more handy now.
I'd be happy if this could be used for other instances of this centrifuge and therefore increase their lifetime.
