Leica Automates Tissue Processing

Leica Microsystems of Bannockburn, Ill., has introduced the ASP 300 Tissue Processor for histopathological sample processing. Unlike its predecessor, the TP 1050, the ASP 300 processor is a fully enclosed, fully automated, stand-alone system capable of processing up to 300 cassettes. The system features SMART operating software and an easy-to-use color touch screen. Users can create customized programs that are automatically launched with the touch of a button using the system's Smart-Start func

Product manager Patrick Devor explains that one of the most significant new features of the ASP 300 is its reagent management system, which keeps track of the cleanliness of all reagents used, including paraffin. The system uses reagents in order of freshness, ensuring optimal sample quality. The system's active paraffin clean function lets users remove contaminants easily to extend paraffin life.

The new system also includes several improved safety features. The ASP 300's software monitors all filters and solutions, ensures reagent compatibility, and minimizes reagent carry-over. Hazardous fumes are kept within the enclosed system and are either condensed and collected via an active air handling system or are absorbed by an activated carbon filter. The ASP 300 also features a remote fill and drain system, which allows users to change reagents without direct liquid handling, thus eliminating exposure to hazardous chemicals and hot paraffin. A two-level password security system protects ...
