Abstract: The invention relates to a method for determining an analyte by means of binding reactions, which method comprises: i) applying the sample to an application zone for sample (ASZ) on a flow matrix in which transport of components present in the sample can take place (transport flow), the flow matrix further exhibiting: a) optionally an application zone (AR*Z) for a binding reactant (Reactant*=R*) which is analytically detectable; b) a detection zone (DZ), which is located downstream of ASZ and exhibits an additional binding reactant (Capturer) firmly anchored to the matrix, and in which a complex (signal complex) containing the Capturer and the analyte and/or Reactant* is formed during the reaction, and ii) detecting the signal complex in the detection zone, the measured signal being used for determining the analyte.

Abstract: A unitary test tube holder insert adapted for receiving test tubes. The insert has a first ring to be secured in a hole of a test tube rack. A plurality of spring members extend at one end from the first ring towards a center axis of the ring to resiliently engage the outside of a test tube inserted into the insert. The spring members are connected at their other end to a second ring which is arranged coaxially with the first ring along the center access, and each spring member is curved towards the center axis to exhibit a straight section which extends parallel to the center axis and which resiliently engages the outside of a test tube inserted into the insert.

Abstract: This invention relates to an apparatus and a method for performing fluorometric measurements, and particularly to a fully automated apparatus for measuring the fluorescence of a fluorescent tag contained in a test sample for allergy assays.
