Apparatus and method for biological fluid analysis involving radiation measurement. The apparatus includes a pipetting dispenser having means for directing radiation from the piston thereof generally axially through the liquid in the pipette tube such that the pipetting dispenser serves not only as a means for measuring and mixing liquids, but also serves as a cuvette. The apparatus and method provide maximum radiation path length to accommodate liquids of different optical density. Still another feature of the apparatus and method is the provision of means for removing liquid from the outer surface of a pipette tube, which means are readily adapted to automated procedures. The apparatus in one embodiment is adapted for absorbance measurement of analyte samples, and in another embodiment is adapted for measurement of fluorescent radiation from analyte samples.
