Patent number: 6986837Abstract: A microfluidic controller and detector system and method for performing screening assays are disclosed. The microfluidic controller and detector system comprises a fluidic chip that includes at least two intersecting channels and a detection zone, a fluid direction system comprising an electrical interface configured for electrical contact with the at least two intersecting channels, an optics block having an objective lens disposed adjacent the detection zone, and a control system coupled to the optics block and adapted to receive and analyze data from the optics block. The electrical interface generally includes electrodes configured for electrical contact with the intersecting channels and coupled to electrode channels for supplying electrical input to the electrodes. A reference channel is optionally provided to calibrate the electrode channels.Type: GrantFiled: August 9, 2002Date of Patent: January 17, 2006Assignee: Caliper Life Sciences, Inc.Inventors: Calvin Y. H. Chow, Morten J. Jensen, Colin B. Kennedy, Michael M. Lacy, Robert E. Nagle

Patent number: 5112134Abstract: A multibeam photometric measuring device includes a light assembly comprising a single modulated light source along with a filter assembly for passing only a desired band of wavelengths and an optical system for suitably focusing light from the light source. A plurality of light transmitting means accept light and transmit it individually to each of the plurality of sites disposed on a multi-well sample plate.Enhancement of color distribution resulting from chromogenic reactions is provided by automatic agitation of the reacting agents within the sample wells before a reading is taken at each of the sampling intervals of a kinetic measurement sequence.Type: GrantFiled: January 8, 1991Date of Patent: May 12, 1992Assignee: Molecular Devices CorporationInventors: Calvin Y. H. Chow, Gillian M. Humphries, Viola T. Kung, Michael M. Lacy
