Abstract:
1. An analyzing instrument comprising: a flat cover plate having an air vent and a needle insertion port, a flat substrate having a fluid feed port for introducing a sample liquid, the substrate also having a reacting portion located downstream from the fluid feed port, a capillary formed between the substrate and the cover plate to extend from the fluid feed port and the needle insertion port toward the air vent for transporting the sample liquid to the reacting portion, and a fluid absorber fitted entirely within the fluid feed port of the substrate upstream from the capillary, the fluid absorber having a needle insertion opening, wherein the needle insertion opening of the fluid absorber is aligned with the needle insertion port of the cover plate for allowing insertion of a lancing needle through the needle insertion opening of the fluid absorber, the capillary and the needle insertion port of the cover plate.
