  • Patent number: 7097981
    Abstract: The present invention relates mainly to reaction vessels, to sets of such vessels for automatic immunological assay apparatuses, to automatic immunological assay apparatuses making use of such sets of vessels, and to a method implementing sets of such vessels. According to the present invention, photometric detection is implemented of the luminescence of a reaction mixture found in a reaction vessel, the apparatus and/or the vessel guaranteeing light-tightness so as to prevent entry of external light falsifying the measurement. Advantageously, sets of vessels in accordance with the present invention are made out of a material that is opaque. The present invention is particularly applicable to detecting the presence of a chemical or a biological substance in a sample. The present invention applies mainly to medical analysis and research.

  • Patent number: 6958130
    Abstract: An automated immunological assay apparatus is disclosed. The apparatus includes a frame carrying device for supporting samples to be analyzed, a device for supporting reagents, and a device for displacing sets of reaction wells along a rectangular path. A cog belt extends along the long sides of the path and a mechanism for transverse displacement extends along the short sides of the path. A device is also provided at one end of the path for automatically feeding sets of reaction wells.
