Universal high pressure liquid connector |
摘要 |
The present invention is a universal self-adjusting high pressure liquid connector for use with high pressure liquid chromatography (HPLC) columns requiring liquid-tight and leak free seals between fittings and unions. The present apparatus provides a liquid-tight seal between the end of a HPLC end fitting and a end cap thereby eliminating any potential dead volume in the area of the connection. The apparatus comprises a body, a fixed ferrule, a replaceable ferrule, a stem disposed in the body and a biasing spring slidingly mounted on a capillary tube of that extends through the connector. The spring biases the capillary tube of the connector into the HPLC end fitting, self-adjusting and maintaining a pressure sufficient to ensure a liquid-tight seal notwithstanding the depth of the HPLC tube stop or ferrule stop of the mating HPLC column.
