Filed:

May 10, 2004

Appl. No.:

10/842288

Inventors:

Samuel A. Ellis - San Diego CA, US
Jeffrey L. Harlan - Corona CA, US

Assignee:

Scientific Plastic Products, Inc. - Oceanside CA

International Classification:

B01D 15/08

US Classification:

210656, 2101982

Abstract:

A low pressure liquid chromatographic cartridge is provided having a tubular polymer container adapted to receive a chromatographic packing material. The container has an outlet port located at a downstream end of the container and container threads formed on an upstream end of the container. A polymer cap having cap threads located on the cap threadingly engage the container threads. An inlet port is located on an upstream end of the cap. A resilient fluid tight seal is interposed between the polymer cap and container suitable for use in low pressure liquid chromatography. A locking tab on a skirt of the cap engages a recess on the container when the seal engages the cap and container to lock the cap in position relative to the container.

The container has an outlet port located at a downstream end of the container and container threads formed on an upstream end of the container. A polymer cap having cap threads located on the cap threadingly engage the container threads. An inlet port is located on an upstream end of the cap. A flange depends from the cap and 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. A locking tab on a skirt of the cap engages a recess on the container when the seal engages the cap and container to lock the cap in position relative to the container. Alternatively, continuous screw threads on the cap and container may hold the parts together.

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.

International Classification:

C12M 1/00
C12M 1/22

US Classification:

4353051

Abstract:

A method and apparatus are provided for transferring growth media or infection fluids to a bioculture bag having Could Process fitting thereon in fluid communication with the inside of the bag. The media or fluid is placed in a flask. A cap is threaded onto the neck of the flask. The cap has a spout with an opening in a distal end of the spout and a vent hole in the cap. The spout has a tubular end in which the opening is formed, with an O-ring seal adjacent the distal end of the tubular end. The tubular end fits within the fitting and the seal forms a fluid tight seal with the fitting to allow fluid transfer to the bag in reduced time with reduced spillage. The cap is preferably used on a flask having shaped baffles in the bottom. The baffles are highest toward the centerline, and decline in height linearly toward the corners of the flask at an angle of about 9 to the horizontal. The flask is rotated about 80-180 RPM, and the baffles have leading and trailing sides in the direction of rotation that are inclined at about 32 relative to the vertical.
