Abstract
A sample segment including a body and wells formed therein, selected wells including a flat exterior surface surrounding a tapered end. The sample segment may retain selected reagents, and a sealing cover is held by ribs, stretched and pressed against raised bosses formed around the well openings to provide a sure seal. The bosses are discontinuous between adjacent wells. Selected wells may contain a free mixing element for enhanced mixing. The segment is uniquely adapted for automated handling and processing.
