Abstract
A capillary valve, connector and router where one or more cylindrical fibers, which may be capillaries, plugged capillaries, optical fibers, or the like, including at least one capillary tube are contained in a first bundle of fibers that terminates at a first face. A second cylindrical bundle of fibers also containing one or more fibers including at least one capillary tube terminates in a second face abutting the first face. A fastener or adapter holds the members together with faces in mutually biased alignment. Connection of a plurality of macroscale pumps enables push-pull fluid motion, with routing, in a capillary system formed by a plurality of fibers coupled by switches, connectors and routers. Chemical reactions, separations and analysis may be carried out with microliter volumes or smaller.
