November 12, 2018. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesLaboratory trays with lockable covers Method and apparatus for dielectrophoretic manipulation of chemical species Silicon semiconductor wafer for analyzing micronic biological samples Method and device for moving molecules by the application of a plurality of electrical fields Easy grip bottle Multiwell in-vitro fertilization plate Analysis based on flow restriction Mesoscale polynucleotide amplification device and method Fully integrated miniaturized planar liquid sample handling and analysis device Partitioned microelectronic and fluidic device array for clinical diagnostics and chemical synthesis InventorApplicationNo. 190428 filed on 11/12/1998US Classes:422/99, Miscellaneous laboratory apparatus and elements, per se73/864.91, Sample holder204/451, Capillary electrophoresis204/452, With detailed detection204/600, Electrophoretic or electro-osmotic apparatus204/601, Capillary electrophoresis type204/603, With detailed detection system (e.g., including a light source and a camera, etc.)206/261, Casing formed of two hinged complementary covers206/263, Having retaining member215/395, Container support220/755, Specified gripping structure (i.e., the handle portion that is contacted by the hand)220/771, Handle is of one-piece construction with a container356/244, SAMPLE, SPECIMEN, OR STANDARD HOLDER OR SUPPORT (E.G., PLATES OR SLIDES)356/246, Fluid containers (e.g., cells or cuvettes)422/82.05, Measuring optical property by using ultraviolet, infrared, or visible light422/100, Pipette or other volumetric fluid transfer means422/104, Holder, support, housing, or hood422/108Control element responds proportionally to a variable signal from a sensorExaminersPrimary: Gulakowski, RandyAssistant: Carrillo, Sharidan Attorney, Agent or FirmForeign Patent References
International ClassB01L 003/00AbstractMicrofluidic apparatus which include a planar device and polymeric holder assembly are provided. The polymeric holder assembly includes a cavity disposed through the holder, providing optical access to the top and bottom of the planar device when the device is mounted in the polymeric holder. The planar device includes microscale channels disposed within the device.Other References
