  • Patent number: 7507377
    Abstract: This invention relates to a device usable in an automatical apparatus for the determination of the rate of change of the physical state of a medium. This device has a series of cuvettes having two opposites shoulders which extend in the plane of the opening of the cuvette and a flexible film which is fixed on the shoulders. This film is provided with a series of oblong opening respectively arranged above the cuvette openings. An optical detection station is provided which has a light source generating a light beam which illuminates the upper face of the cuvette bowls and an optoeleclectronic detector placed below the bottom of the bowls.

  • Publication number: 20050175502
    Abstract: The invention relates to a device comprising a series of single-use cuvettes (C), each with a base, an upper face opposite said base with an opening and two opposing flanges (R<sb>1</sb>, R<sb>2</sb>) which each extend from the cuvette essentially in the plane of the opening. Said cuvettes are arranged side by side and fixed to each other by means of a flexible film (3) fixed to said flanges (R<sb>1</sb>, R<sb>2</sb>) and at least partially covering the openings of said cuvettes (C). Said film is provided with a series of openings (4) respectively arranged to the right of said openings on said cuvettes. The above finds application in an automatic analytical apparatus, particularly for the determination of the rate of change of the physical state of a medium.

  • Patent number: 6135172
    Abstract: The invention concerns a hollow needle axially mobile so as to pierce a container stopper. Said needle comprises a pointed end with a cutting edge tangent to the needle cylindrical body generatrix, an oblique shape linking the edge to said cylindrical body and a side outlet orifice of the channel centred on said generatrix and a site spaced from the edge, said orifice being centred perpendicular to the needle longitudinal axis. This invention is applicable to automatic and semiautomatic analytical equipment.
