Abstract

A one piece, injection molded single piece, well container suitable for reagents for use in a clinical instrument such as a protein analyzer, normally molded from a high density polyethylene or other recyclable plastic. The container is one or more wells, uses standard caps, and is readily adapted to automatic filling equipment. The molded, single piece reagent cartridge is used in a clinical instrument, the reagent cartridge comprised of a plurality of storage wells located in a line in fixed relationship. The reagent cartridge has a guide at one end which is engageable with a means on the receiving means on an analyzer to restrain the cartridge from radial or lateral movement. Each of the wells has side walls and a closed bottom, and the side walls have an upper terminal position including an access opening. An integrally formed hollow shell open at the bottom and otherwise substantially enclosing said wells from a point below the terminal portion is provided to form a hollow space within the shell around the exterior of the wells to permit the flow of conditioned air around the walls. Positive retention is provided by forming a hole through the wall, which engages a detent formed on the retention means.
