| Abstract: | A micromanifold for connecting external capillaries to the inlet and/or
outlet ports of a microfluidic device can employ a ferrule/capillary
assembly that includes: (a) a ferrule comprising an elongated member and
having a bore traversing from a proximal end to a distal end of the
member, wherein the bore has an inner surface and wherein the distal end
of the ferrule has a tapered, threaded exterior surface, and (b) a
capillary that is positioned within the bore wherein the capillary's
outer surface is in direct contact with the bore's inner surface. No
mating sleeve is required for the one-piece ferrule. Alternatively, the
capillaries can be bonded to channels that traverse the manifold and
therefore obviate the need for a ferrule. |
