摘要

Simply moving the valve body without being projected to the column inside the moveable plug, was recovered from the column packing material used, or to inject the column matrix into the column, further, supply and associated with the valve itself discloses a chromatographic preparative column that can be used, respectively, to clean the drain line, one or more valves are provided. Each valve is attached to the side wall of the column just above the filter plate in the column bed, the plug between an open position the plug is recessed within the bore and a closed position is flush with the inner wall of the column end surface of the plug I can move between. Each valve has a port further two in the valve body, one of the holes at least the port when both ports are open to the valve hole when the plug is closed, the plug is released As can be opened by hand, the port is located.
