Flash chromatography cartridge

摘要

A low pressure liquid chromatographic cartridge is provided having a tubular polymer container 20 adapted to receive a chromatographic packing material 60. The container has an outlet port located at a downstream end of the container and container threads 34 formed on an upstream end of the container. A polymer cap 28 having cap threads 36 located on the cap threadingly engage the container threads. An inlet port 30 is located on an upstream end of the cap. A flange 48 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.
