Flash chromatography cartridge

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.

1 . A low pressure liquid chromatographic cartridge, comprising:
 a tubular polymer container adapted to receive a chromatographic packing material, the container having an outlet port located at a downstream end of the container and configured for connecting to chromatographic equipment during use of the cartridge, the container having container threads formed on an upstream end of the container;   a polymer cap having an inlet port located on an upstream end of the container, the port being configured for connecting to chromatographic equipment during use of the cartridge, the cap having cap threads located on the cap to threadingly engage the container threads;   a resilient fluid tight seal interposed between the cap and container suitable for use in low pressure liquid chromatography; and   a locking tab on a skirt of the cap, the locking tab being located and configured to engage a recess on the container when the seal engages the cap and container to lock the cap in position relative to the container.
