Self-washing injection apparatus Ä101Ü for liquid chromatography injection valves utilizes an interior chamber Ä105Ü with a penetrable seal Ä109Ü at the top end of the chamber and a needle sleeve seal Ä113Ü at the bottom end of the interior chamber. A wash port Ä145Ü in the body Ä103Ü of the apparatus connects one or more sources of wash fluid to the interior chamber between the penetrable seal and the sleeve seal. The apparatus provides a simple and effective means to aspirate or pump wash fluids from one or more wash fluid reservoirs through the apparatus, the injection port of the injection valve, and associated components. <IMAGE> |
