ABSTRACT:
An apparatus and method for sealing cartridges used in liquid chromatography. Such cartridges are commonly filled with media beds that are bounded axially by porous plates. The invention involves one or two sealing heads. Each sealing head comprises two slidably connected head pieces and an elastomeric sealing member. The head pieces and the elastomeric sealing member are sized to slide easily into an open end of a cartridge when the elastomeric sealing member is uncompressed. After insertion, relative movement of the head pieces compresses the elastomeric sealing member and causes the elastomeric sealing member to expand laterally so that it forms a seal against the cartridge, when the sealing head is pressed against the media bed or porous plate.
