Used. Tested and spins up but it has some issues. When we tried to run it in the normal mode it would spin up to around 500 RPM and then give an error 8 code. If the "soft" button was pressed it would spin up to a maximum 12500 RPM and then when the run was over and it was slowing down it would give an error 6 code. Other than these issues, the centrifuge worked great. Even though it works in soft mode, because of the error codes, this centrifuge is being sold as parts- not working. The rotor is not included.
