  • Reaction support incorporating multiple recipients for testing liquid doses
    Patent number: 4656009
    Abstract: The invention relates to a reaction support incorporating multiple recipients for testing liquid doses, comprising a transparent plate provided with a plurality of recesses of which each forms one of the recipient. According to the invention, this support is characterized in that the plate is in the form of a disc and in that the recesses are obturated at the top and are each in communication with the outside via an eccentric orifice opening on the upper face of the disc. The invention is particularly applicable in the domain of biology.

  • Process and device for the detection and quantification of agglutinates
    Patent number: 4575492
    Abstract: The present invention relates to a process and device for the detection and quantification of agglutinates, in recipients of which at least the bottom are transparent. According to the invention, it is decided that there is agglutination when, at the same time, the calculated mean value of the bottom of the reaction studied is higher than that of a reference sample and when there exist points of measurement whose transmission is less than said threshold, and, on the other hand, that there is no agglutination when, at the same time, this calculated mean value is not greater than that of said reference sample and when there exist no points of measurement whose transmission is less than said threshold. The invention is more particularly applicable to immunohaematology.
