<p>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. Said apparatus comprising, an excitation radiation source (6) including an incandescent filament (30) cooperating with, an optical unit (4) for providing light of an appropriate wavelength for excitation of the fluorescent tag contained within the test sample, and for collecting the emitted fluorescent radiation without disturbances from the excited wavelength, an electronic unit (2) for controlling the intensity of the incandescent filament (30) of the excitation radiations source (6) and evaluating the emitted fluorescent radiation, said optical unit (4) comprising an L-shaped light channel (34), and a capillary tube (8) movably provided at the centre of the intersection between the two legs of the L-shaped light channel (34) and aligned with the incandescent filament (30), said capillary tube (8) being moveable between two positions and being repeatedly, between each measurement, suppliable with a new test sample.</p> |
