Reaction tube assembly for automatic analyzer

摘要

An assembly comprises a disc having an annular array of a number of reaction tubes formed adjacent to the periphery thereof. Each reaction tube is U-shaped and has its one end formed as an open-ended reaction chamber and its other end functioning as an air supply port. The link portion between the reaction chamber and the port is made transparent, forming a flow cell which permits the transmission of light which is used for the purpose of analytical determination. The assembly permits treatment with a reagent of a sample for reaction as well as a photometry for colorimetric analysis of the sample solution obtained by the reaction treatment of the sample.
