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.
