The Thermo Gemini AS Automated Slide Stainer delivers high-throughput staining capabilities to the busy histology laboratory. With its new intuitive touch-screen interface, operation is easy-to-learn and simple-to-use.

The unique dual-level design, with integrated power supply and touch-screen, ensures maximum space savings. With its small footprint, the Thermo Gemini AS Automated Slide Stainer can be placed near the sectioning area for optimal workflow. The intelligent look-ahead control software provides the ability to run up to 12 slide racks simultaneously with minimal reduction in speed. The “urgent” feature enables a rack to be given priority for MOHS surgery or similar STAT needs. The five heated stations provide maximum throughput without the need for a separate drying oven.
