Patent number: 8758707Abstract: An apparatus and method for applying reagents to tissue mounted on slides, in the field of histology is disclosed. The apparatus holds a number of slides, in slide trays, which are loaded onto the apparatus. Each slide tray forms a batch of slides, with all the batched forming a group. The apparatus holds a number of reagents, grouped into a first group comprising bulk type reagents, and a second group comprising antibodies or probes, and detection systems, for identifying elements of the tissue. A group fluid dispenser, in the form of a robot arm, dispense reagents to the group of slides. Each batch of slides has its own batch fluid dispenser to dispense reagents onto the batch of slides. In on embodiment, the group fluid dispenser dispense antibodies, probes, detection reagents to all slides depending on the protocol defined for each slide, and the batch dispensers dispense bulk reagent to each batch, thus freeing the group fluid dispense from dispensing bulk reagents to all slides.Type: GrantFiled: June 16, 2009Date of Patent: June 24, 2014Assignee: Leica Biosystems Melbourne Pty LtdInventors: Andrew Watkins, Nathan Ray, David Huang

Patent number: 8425863Abstract: A micro fluidic device includes a valve/pump-unit with reduced dead volume having a substrate. The lower surface of the substrate includes two micro channels spaced apart by a valve area of the substrate that separates the two micro channels. A flexible membrane is arranged on the lower surface of the substrate facing an actuating element located in a through going cut-out of a cover element. Movement of the actuating element towards and away from the valve area of the substrate causes a pump and/or valve action of the flexible membrane area, respectively, to cause or stop a directed fluid flow between the two micro channels through a channel formed between the valve area of the substrate and the flexible membrane.Type: GrantFiled: December 12, 2007Date of Patent: April 23, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Chris Van Haag, Ronald Cornelis De Gier, Adrianus Wilhelmus Dionisius Maria Van Den Brijgaart, Gheorghe Sorin Stan

Patent number: 8343774Abstract: An analytical apparatus includes a sample-injection valve, a sample pump, at least two sources of standards, and a selection valve. The sample-injection valve has an output port in fluid communication with a LC column, and an input port in fluid communication with a mobile-phase supply line. The at least two sources of standards are associated with at least two pharmaceutical compounds. The selection valve fluidically and selectably connects the sample pump to the at least two sources of standards, to the sample-injection valve, and to at least two pharmaceutical-manufacturing process lines associated with the at least two pharmaceutical compounds. A method for controlling a pharmaceutical manufacturing process includes switching the selection valve to alternately and repeatedly sample the at least two sources of standards and material flowing through the at least two pharmaceutical-manufacturing process lines.Type: GrantFiled: February 25, 2009Date of Patent: January 1, 2013Assignee: Waters Technologies CorporationInventor: Sylvain Cormier

Patent number: 8298763Abstract: An automated real-time flow-through system capable of processing multiple samples in an asynchronous, simultaneous, and parallel fashion for nucleic acid extraction and purification, followed by assay assembly, genetic amplification, multiplex detection, analysis, and decontamination. The system is able to hold and access an unlimited number of fluorescent reagents that may be used to screen samples for the presence of specific sequences. The apparatus works by associating extracted and purified sample with a series of reagent plugs that have been formed in a flow channel and delivered to a flow-through real-time amplification detector that has a multiplicity of optical windows, to which the sample-reagent plugs are placed in an operative position. The diagnostic apparatus includes sample multi-position valves, a master sample multi-position valve, a master reagent multi-position valve, reagent multi-position valves, and an optical amplification/detection system.Type: GrantFiled: February 27, 2008Date of Patent: October 30, 2012Assignee: Lawrence Livermore National Security, LLCInventor: John Frederick Regan
