Abstract: A multi-port valve useful in chromatography or other analytical chemistry processes utilizes a ferrule and clamp assembly to connect a number of tubes or capillaries to a common port in the valve. The use of the clamping assembly, as opposed to conventional connectors such as nuts and/or bolts, permits the capillary ends to be positioned in extremely close proximity to the valve rotor and to each other, thus minimizing the volume between two capillaries when they are in brought into fluid communication with each other. At the same time, the clamps allow for easier connection and disconnection of the tubes or capillaries from the valve body. An operator can twist a screw to tighten the clamp and create a sealed connection without the need for special tools.
