SAMPLE SEGMENT

摘要

A sample segment (10) including a body and wells (14) formed therein, selected wells (14b, 14f) including a flat exterior surface (56) surrounding a tapered end (64). The sample segment (10) may retain selected reagents (80), and a sealing cover (90) is held by ribs (74, 76), stretched and pressed against raised bosses (70) formed around the well openings (44) to pronde a sure seal. The bosses (70) are discontinous between adjacent wells (14). Selected wells may contain a free mixing element (82) for enhanced mixing. The segment (10) is uniquely adapted for automated handling and processing.
