The Thermo Scientific Cytospin 4 Centrifuge and Rotor is a competitively-priced product that is fully functional. It has undergone testing and powers up easily, with smooth spinning and a lock-and-unlock lid mechanism as shown in the provided pictures.
However, we are selling this unit as "Parts Only" due to some broken plastic areas on the lid railing. While the unit still runs perfectly, we are unable to fix and reconnect the lid. If you have the expertise to reconnect and repair the lid, this is an excellent value for the price.
