  • Publication number: 20040017981
    Abstract: A capillary connector having one or more capillary tubes entering a first end and terminating with an open end at a level face on the opposite side of the connector. The face is held by a coupler and brought into a biased abutment such that the open capillary ends are in fluid communication with the ends of microchannels on an abutting surface. These microchannel ends may be capillary tube ends from a second capillary connector or may be openings of microchannels on a substrate. The connector may be a fiber-optic connector modified to hold capillary tubes. Alternatively, the connector may be a substrate having microchannels extending through the substrate and terminating at a level face on the substrate. The coupler may receive the capillary tube, which passes through the coupler. This coupler may be attached to a substrate surface to allow the capillary connector to be joined to the substrate.
