Flow cells for biological or chemical analysis
First Claim
1. A flow cell comprising inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween, the flow channel including a diffuser region and a field region that is located downstream from the diffuser region, the flow channel also including a collector region that is located downstream from the field region and configured to receive fluid from the field region, the diffuser region being shaped to increase a cross-sectional area of the flow channel as the diffuser region extends downstream in a first fluid flow direction, the field region of the flow channel directing fluid along reaction sites where desired reactions occur, wherein the fluid flows through the field region in a second flow direction, the first and second flow directions being perpendicular, wherein the fluid is configured to flow through the collector region in a third flow direction that is different than the second flow direction, the collector region being shaped to reduce a cross-sectional area of the flow channel as the collector region extends downstream in the third flow direction.

Abstract
A flow cell including inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween. The flow channel includes a diffuser region and a field region that is located downstream from the diffuser region. The field region of the flow channel directs fluid along reaction sites where desired reactions occur. The fluid flows through the diffuser region in a first flow direction and through the field region in a second flow direction. The first and second flow directions being substantially perpendicular.

4. A flow cell comprising inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween, the flow channel including a diffuser region and a common field region that is located downstream from the diffuser region, the field region of the flow channel directing fluid along reaction sites where desired reactions occur, wherein the fluid flows through the diffuser region in a first flow direction and through the field region in a second flow direction, the first and second flow directions being perpendicular;
wherein the diffuser region comprises a plurality of inlet channels that provide fluid to the field region, the inlet channels being spaced apart from each other along a dimension of the field region that extends perpendicular to the second fluid direction. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
