Abstract:
1. A device for isolating one or more sample components of a sample material following separation of the sample material into a plurality of sample components, comprising: a separation channel having a first end and a second end, the separation channel having a separation channel axis along a straight length of the separation channel at the second end; a loading well disposed in the separation channel; a collection leg having a first end and a second end; a collection well disposed in the collection leg between the first and second ends of the collection leg; a waste leg having a first end and a second end; and a switching region having an inlet end and an outlet end; a first pinching channel having a first end and a second end, the first pinching channel having a first pinching channel connection portion, the first pinching channel connection portion having a first pinching channel axis along a straight length of the first pinching channel connection portion at the second end of the first pinching channel; a second pinching channel having a first end and a second end, the second pinching channel having a second pinching channel connection portion, the second pinching channel connection portion having a second pinching channel axis along a straight length of the second pinching channel connection portion at the second end of the second pinching channel; wherein the second end of each of the first pinching channel, the second pinching channel, and the separation channel are in fluid communication with the inlet end of the switching region; the separation channel axis is perpendicular to the first pinching channel axis, the separation channel axis is perpendicular to the second pinching channel axis, and the first pinching channel axis and the second pinching channel axis are collinear; and the first end of the collection leg and the first end of the waste leg are in fluid communication with the outlet end of the switching region.
