摘要

The assay apparatus includes: (1) a sample module (A) connected to a control microprocessor; (2) a reaction module (C) consisting of a plurality of tube supports (Tr) for successively receiving an aliquot amount of said samples and an aliquot amount of a suitable reagent, and of a washing device which comprises at least one means for applying a magnetic field to the lower part of the reaction tubes (Tr) containing the sample to be analysed and one or more suitable reagents for the assays to be carried out, at least one of said reagents having the form of magnetic balls, and a washing head (L) comprising at least one means (20) for sucking out the liquid contained in said tubes, at least one means (21) for delivering a washing liquid to said tubes, and optionally at least one means (22) for delivering a suitable substrate; (3) a reagent module (E) in which at least one of the reagents is in the form of magnetic balls; (4) means for taking and delivering (B) and (D) samples and reagents from the tubes in said reaction module; (5) a suitable means for reading the reaction carried out in the reaction module; and (6) an information processing system comprising a computer for controlling the various modules and means (1) to (6) and performing a series of analytical cycles.
