Abstract

A microfluidic valve comprises: a substrate, relief-patterned at top and bottom surfaces to define: an annular valve seat and a surface for holding an elastomeric membrane inside a generally cylindrical protuberance in the top surface so that the membrane covers the cylindrical inner wall. The relief patterning also provides a through bore defining one valved microfluidic channel and an annular trough around the annular valve seat to which at least one other valved microfluidic channel extends. When the cap is pushed into the recess, it reversibly presses the membrane against the valve seat to form a seal that prevents fluid flow in the channel.
