Abstract
A photometer for sensing the optical density of a plurality of liquids located in a microtray provided with a rectilinear array of wells is provided with a detent device for locating each well in alignment with the photodetector and a plurality of magnets associated with the microtray and a plurality of magnet sensors associated with the photodetector for providing signals indicative of the specific well in alignment with the photodetector. A carrier having two bar magnets disposed at right angles to each is provided for supporting the microtray with the two bar magnets disposed parallel to adjacent sides of the microtray. Two linear arrays of equally spaced magnet sensors extend outwardly from the location of the photodetector at right angles to each other and at right angles to the bar magnets, respectively.
