  • Device having a liquid flowpath
    Patent number: 7008521
    Abstract: A micro-reactor is provided with a mixture of channels having larger cross-sectional areas (17?,22?,25?,27?,31?,33?) and channels having smaller cross-sectional areas (40a?,40b?,40c?). The smaller channels (40a?,40b?,40c?) resist liquid movement driven by hydrostatic force but allow liquid movement driven by electro-osmotic force. Accordingly liquid flow is almost entirely driven by electro-osmotic force. The smaller channels (40a?,40b?,40c?) are formed by etched grooves which are closed by a planar surface 13. This allows the cross-sectional areas of the smaller channels to be closely and reproducibly controlled.
    Type: Grant

  • Device having a liquid flowpath
    Publication number: 20030052010
    Abstract: A micro-reactor is provided with a mixture of channels having larger cross-sectional areas (17′,22′,25′,27′,31′,33′) and channels having smaller cross-sectional areas (40a′,40b′,40c′). The smaller channels (40a′,40b′,40c′) resist liquid movement driven by hydrostatic force but allow liquid movement driven by electro-osmotic force. Accordingly liquid flow is almost entirely driven by electro-osmotic force. The smaller channels (40a′,40b′,40c′) are formed by etched grooves which are closed by a planar surface 13. This allows the cross-sectional areas of the smaller channels to be closely and reproducibly controlled.
