Overview
The Leica St4020 Linear Stainer is designed for rapid and efficient staining of surgical frozen sections, ideal for urgent diagnostic needs. Its compact size allows it to be placed alongside a cryostat, ensuring quick processing.

Speed and Productivity
The stainer supports high throughput with the capacity to handle up to 72 slides simultaneously. It offers a fast processing time, potentially as short as 30 seconds, and features a walk-away convenience with a collection tank for 16 slides and a protocol-finished alarm. Continuous loading is possible with the ability to add a rack of four slides at each interval.

Quality
The Leica St4020 maintains high diagnostic quality with features such as fresh reagent use, optional agitation, and customizable protocols. It supports the use of running water for optimal rinse quality and has a small reagent container volume of 50 mL to facilitate regular changes and cost efficiency.
