  • Patent number: 4501496
    Abstract: A transparent specimen slide is made up of a series of isolated specimen viewing surfaces, each surrounded by a channel or groove and a shallow well communicates with each channel and with a notched portion which projects into the viewing surface from the channel opposite to the well of each channel. Pads are formed at spaced intervals along the top surface of the slide together with locating ribs in order to properly position a cover slip in predetermined spaced relation to the viewing surface portions so that when a liquid specimen is deposited in each well it is free to flow by capillary attraction uniformly over the viewing surface portion.

  • Patent number: 4335730
    Abstract: A urine specimen collector assembly includes a specimen tube and funnel-shaped member wherein the specimen tube is characterized by having a lower reinforced reservoir tip of reduced diameter so that the tube is adapted for use with centrifuge machines for the precipitation of a measured quantity of solid materials in the tip from the specimen placed in the tube. The mouth of the tube is outwardly flared to conform to the shape of the outlet end of the funnel, and the funnel has a ribbed internal surface to direct the flow of liquid through an elongated outlet tip for insertion into the specimen tube so that the tube and funnel may be filled with fluid. Upon inversion, a user may empty all but a measured quantity of fluid from the tube.
