The EVOS XL Core Attachable Mechanical Stage (Cat. No. AMEP4712) is an optional feature, that can be purchased separately. It is an alternative to the universal, fixed stage provided with the EVOS XL Core Imaging System and allows for easier manipulation of sample vessels and slides. This mechanical stage has X-Y axis controls and a vessel holder framework that accommodates our broad range of vessel holders for smaller sample vessel types, such as microscope slides and 35 mm dishes. Larger sample vessels, such as T-75 flasks or multi-well plates, fit directly onto the stage.
