  • Analytic reader device
    Patent number: 5057275
    Abstract: An analytical reader device having an elongated fixed standard tray supporting thereon a strip of standard wells and an elongated movable sample tray supporting thereon a strip of sample wells. A track arrangement connects and allows the movable sample tray to slide along the fixed standard tray. A rack gear is secured along the side of the movable sample tray opposite to the track arrangement. A geared dial is rotatably supported on a support plate secured to the fixed standard tray. The teeth of the geared dial mesh with the teeth of the rack gear so that as the movable sample tray slides the dial rotates. When a sample well is positioned adjacent the visually similar standard well, the dial is turned so that the correct concentration reading thereon appears through a fixed readout window.
