1. A microfluidic apparatus, comprising:

  • a microfluidic device comprising a planar substrate having a first surface and at least two edges, at least two intersecting channels disposed in the substrate, a detection window in the first surface which permits transmission of an optical signal from at least one of the at least two intersecting channels;

    a holder assembly having a second surface and a cavity disposed therein, the cavity being configured to fixedly receive the microfluidic device; and

    a manual handling structure integrated with the holder assembly, wherein the manual handling structure is selected from the group consisting of raised ridges disposed on said second surface of the holder assembly and beveled edges positioned on said holder assembly and adjacent to said at least two edges of said substrate of said microfluidic device for gripping said holder assembly without contacting said microfluidic device.
