Thanks for the advice everyone. I've tried turning in both directions, but the rotor just turns in either direction, so without being able to stop the rotation it's hard to tell if any direction feels better. I think I might need some kind of tool to get better leverage/immobilize the rotor. I will give an update if I succeed.

I recently bought an Eppendorf 5415D centrifuge, and have tried to remove the rotor for cleaning and inspection. I don't have a rotor key of the kind that is sold by Eppendorf, but the item description at http://www.capitolscientific.com/Eppendorf-022667181-Rotor- seems to indicate it's just a standard 10 mm socket wrench, so I bough one of those. (https://www.amazon.com/gp/Key-for-Microcentrifuge- Models-5415-D-5415-R-10mm- Socket-Wrench product/B0028N57SW ). I attempted to use the socket wrench on the hexagonal part in the centre (see the picture), but that just makes the whole rotor turn. I tried to keep the rotor in place while turning the wrench, but that didn't work either (I couldn't keep the rotor still).If I try to lift the rotor upwards, the centrifuge hangs from it and I'm worried about damagaging it so I didn't try that very hard.The centrifuge manual (http://www.nist.gov/ncnr/upload/Eppendorf_5415R_ ) doesn't go into detail about how to remove the motor. It mentions bending the rotor to one side if it's stuck, but how do I know if it's stuck in the way which is solved by doing that?Centrifuge_Manual.pdf
What do I need to do?Picture of the rotor: https://drive.google.com/file/d/ 0B9aq85qBYTsWZm5tamh0QWRJSFE/ view?usp=sharing Best regards,JP
