ABSTRACT:
The invention provides a separation column useful for liquid-solid column chromatography. In an exemplary embodiment a polytetrafluorethylene tube is provided which is threaded on each end. Threaded polytetrafluorethylene fittings mate with the threads of the tube, and compress an O-ring on each end of the tube, to form a liquid-tight sealing of the tube under pressurized or non-pressurized use. The threaded polytetrafluorethylene tube may be vacuum packed in a plastic bag with a chromatographic medium retained within the polytetrafluorethylene tube. The chromatographic medium may be formed from one or more layers of chromatographic material. Another embodiment incorporates permeable polytetrafluorethylene discs, known generally as frits, in gravity fed polytetrafluorethylene separation column.
