Abstract
An improved sample card is provided. The improved card, typically used in biochemical analysis, achieves high sample well capacity and improved fluid flow, including by means of a plurality of through-channels which route the fluid flow of samples along both the front and back surfaces of the card. Elevated bubble traps are provided, as are integral interrupt slots for sensing card position and alignment. A bezeled leading edge facilitates insertion.
