This rotor let loose while spinning damaging the bottom of it. Putting this out there for parts or repair. It's no longer recommended for use. Some shops may have the ability to repair this and they would assume any liability for spinning.
This could also be used for decoration in a lab, or a lab inspired theme including decoration in a film production. If you remove the lid, it could be used for a plant pot as well using the slots for individual plants.
The lid is still in good condition as is the hold down knobs and threads. This part of the rotor could still be used.
Willing to separate the two if you would prefer. This would cut down cost of shipping and I would reduce the price as well if you only wanted one of the two pieces.
If you have any comments, questions or concerns, feel free to contact me and I will get back with you promptly. Thanks!
