    Abstract: The present invention relates to a device (1) and a method for determining parameters of fluid-containing samples (2) in a system (3) for individually irradiating the samples (2) with light (4) of a light source (5) in an essentially vertical irradiation direction (6). In this case, this system (3) includes a detector (7) for measuring the light (8) coming from a single sample, and this detector (7) has a detection direction (9′), which lies on an optical axis (9) that is essentially parallel to the optical axis (6) of the light source (5). This device (1) includes at least one reflective surface (10), using which the light (4) coming essentially vertically out of the light source (5) may be at least partially deflected in an essentially horizontal irradiation direction (11). The device according to the present invention and the method according to the present invention are distinguished in that the detection direction (9′) of the detector (7)—for measuring the individual light (8) coming from a single sample (2)—is positioned at an angle to the optical axis of the light (4) irradiating the sample (2) in such a way that only the light (8) coming from the individual sample (2), but not this light (4), reaches the detector (7).

    Abstract: A system uses a photometer that establishes an optical channel between a light emitter and a light detector. The photometer analyses a specimen while it occupies a well in a tray. A movable platform transports the tray to the optical channel for analysis and removes the tray from the optical channel after analysis. The system calibrates the movable platform to assure proper alignment between the specimen and the photometric apparatus used to analyzed the specimen. The system also calibrates the optical channel without use of an external reference.

    Abstract: A rapid method for the simultaneous measurement of aggregation or agglutination in plurality of microtest wells or other sample-holding vessels comprises providing a plurality of light beams having discrete focal points adapted to be focused on the contents of a plurality of wells or other vessels and a plurality of photodetectors therefor, directing the light beams through the wells or other vessels and contents thereof, continuously agitating the wells or other vessels and contents thereof with a circular movement effective to permit aggregation or agglutination while preserving the integrity of the material, producing a plurality of output signals from the detectors are proportional to the light absorbencies of the beams as they pass through the wells or other vessels and contents thereof, repeatedly sampling the signals at a predetermined time interval and determining changes in optical densities from the signals obtained after each predetermined time interval by comparing each signal sampled after each predetermined time interval with the first signal sampled for the same microtest well or vessel, whereby any change in optical density which is greater than about 0.05 units is said to indicate that aggregation or agglutination occurred in the well or other vessel. The present method is suitably applied to the measurement of aggregation in platelets.

    Abstract: Apparatus for performing and measuring chemical reactions includes a reaction test apparatus having reaction wells wherein reactants are controllably mixed, and exposure apparatus which receives and positions the reaction test apparatus adjacent a photographic film. Each of the reaction wells includes at least two reaction cups, arranged one above the other. The uppermost reaction cups have orifices in the bottoms, so that liquid can be mixed and reacted in the uppermost cup, and then controllably transferred to the lower cup to be mixed with additional reactants. In a preferred embodiment, the reaction cups are supported in plates that are structurally integrated with the cups, and are superimposed to make a test block. The test block is retained in the exposure apparatus, and liquid is forced from the upper cup to the lower cup by application of pressure to the top of the upper cup. The apparatus of the invention is particularly suited for measuring reactions that produce luminescence of short duration, as the reactants can be conveniently mixed in darkness, while the film is being exposed.
