  • Publication number: 20170067862
    Abstract: A low pressure liquid chromatographic cartridge has a tubular polymer container that receives a chromatographic packing material. The container has an outlet port located at its downstream end and container threads formed on its upstream end. A polymer cap, with an inlet port on an upstream end, screws onto the container threads. A flange depending from the cap mates with the lip of the container to form a fluid tight seal between the polymer cap and container suitable for use in low pressure liquid chromatography.

  • Patent number: 7381559
    Abstract: A container is provided for cell growth by artificial cultivation of selected biological material in a growth liquid for use in an oscillating incubator. The container has a circular bottom with rounded corners joining a sidewall that is inclined at an angle toward a longitudinal axis of the container to define a container volume. The bottom has six equally spaced baffles extending inward from the corners and upward toward a large diameter opening of the container centered on the longitudinal axis. The baffles have a triangular cross-sectional shape with an included angle of about 28–40°, and a height measured parallel to the longitudinal axis of about 15–25% of the usable container volume. The baffles end before the longitudinal axis. The container and baffles are blow molded of a polymer suitable for blow molding. An air permeable filter is placed over the container opening, with the filter having an adhesive on one side to stick to the container.

  • Patent number: 5848735
    Abstract: A shell for a water cooler has two side sections and a front section. The side sections slide-connect with the front section and lock in place at corner joints, thereby forming an essentially one-piece shell. The shell may be economically fabricated with only two molds (one for the side sections and one for the front section) and with only the slide-connect step.

  • Patent number: 5645331
    Abstract: A lower front for water coolers for reducing the expense and labor of renovating different brands of used water coolers. In one of its aspects, the apparatus comprises new front panel elements that are substantially identical to each other, and are shaped and adapted to replace corresponding used front panel elements on the used water coolers even though such used front panel elements, and related parts, are different from each other.
