    Abstract: Optical encoding of a cuvette or other object is provided by means of multiple facets molded integrally into flanges or other portions of the object, which facets selectively refract light passing therethrough in accordance with a predetermined code. The detector for the coded light includes a separate detector for each code state of the facets, with the detector having a different output when no facets are between a light source and the detectors. The facets are preferably bevels, which are selectively angled in accordance with the code.

    Abstract: A mechanical pipette having a fixed stroke for aspirating and discharging a predetermined volume of liquid into and from a reservoir. A measuring piston controls the volume of liquid drawn into the reservoir and a substantially larger piston assures that all of the liquid in the reservoir is expelled therefrom on a discharge stroke. On the discharge stroke, a mechanically actuated valve is opened to admit air being compressed by the substantially larger piston into the reservoir.

    Abstract: A package of disposable pipette tips in which tapered pipette tips are supported on trays by projecting through apertures provided in the tray and in which the trays have sidewalls that extend downwardly from the tip supporting surface of the tray a distance greater than the distance the pipette tips project through the supporting surface. The sidewalls of the trays may be configured such that the bottom edge of the sidewall of a tray is supported by a shoulder formed in the sidewall of a tray on which the first tray is stacked. When the trays are thus stacked, the pipette tips on one tray project into the pipette tips on the tray below.

    Abstract: The invention is shown as a two part stand having receptacles for holding test tubes. The first, top part comprises a plurality of vertical receptacles for receiving the test tubes in a close fitting relationship. The second, bottom part is a rack that is interconnected to the top part in an easily detachable manner, and it comprises a base plate and vertical corner posts so that it is possible to look through all four sides of the bottom part of the stand and observe the contents of the test tubes.
