Abstract: A flow cell having a first plate having a continuous groove formed as a passage on one surface of the plate and having gas/liquid inlet/outlet portions at both the ends of the continuous groove, and a second plate to be kept in contact with said one surface of the first plate, wherein at least either of the first and second plates allows light transmission; fixable reacting substances are fixed on the surface of the second plate, to be kept in contact with the first plate, at plural places corresponding to the continuous groove; and the first and second plates are kept in contact with each other to support each other, for establishing the passage of any one of liquid reacting substances common to the plural fixed reacting substances.

Abstract: In the case where many interactional substances are immobilized on the front surface side of a light transmitting plate capable of generating evanescent waves on the front surface, and where the fluorescence levels in the interactions between the interactional substances and a fluorescence labeled test substance are detected in a liquid layer according to a conventional method, the detection sensitivity and S/N ratio are low due to the background noise. Furthermore, it is necessary to perform a gel filtration purification step for the purpose of removing an excessive amount of the fluorescence dye used for labeling a test substance before the interactions between the fluorescence labeled test substance and the interactional substances are performed.

Abstract: In the optical inspection apparatus according to the invention, in a case where an optical change such as white turbidity and white sedimentation, or fluorescence is caused to a sample accompanying the reaction of amplifying an object to be inspected present in a sample tube, sample tubes are stood and arranged in a plurality of arrangement holes formed in a reaction block, an inspection light is irradiated to the respective sample tubes passing through the observation holes formed to the lateral surface or the holes formed in the bottom and optical change such as white turbidity and white sedimentation or fluorescence caused in the sample tube are detected based on the luminance distribution or the chromaticity distribution of image data photographed by the image pick-up camera thereby enabling accurate and rapid inspection for the presence or absence of an object to be inspected.

Abstract: Fractionating apparatus having a plurality of sample elution system (S1-S8) in which a nozzle (N) movable in the direction of the row of fractionation vessels (4, 4, ---) arranged in a matrix is disposes to each of the sample elution system (S1-S8) and kept standing-by just above an empty fractionation vessel (4), a valve (30) is operated when elution of sample ingredients is detected by photosensor (PD1-PD8) to drop the sample ingredients to the fractionation vessel (4, 4, ---) and the nozzle is moved after dropping the sample ingredient by a required amount, and in which the nozzle (N) and the valve (30) can be operated individually on every sample elution systems at different timings respectively such that the eluate can be dropped at different timing on every sample elution systems.
