The EVOS XL Core Mechanical Stage is an alternative to the universal, fixed stage provided with the EVOS XL Core Imaging System. 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. Both vessel holders and large vessels are held securely in place by a stage clip during operation. The spring-loaded clip allows fast and easy vessel changes, such as during operations inside a hood or during processing of multiple samples.
