20080311001 | REACTION CUVETTE FOR AUTOMATIC ANALYZER AND METHOD OF SURFACE TREATMENT FOR REACTION CUVETTE - The present invention provides a highly reliable reaction cuvette in which air bubbles are adhered little and mutual contamination can be prevented among samples and reagents in adjoining reaction cuvettes, a method of surface treatment for a reaction cuvette, and an automatic analyzer with the reaction cuvette mounted therein. | 12-18-2008 |
20090041622 | AUTOMATIC ANALYZER - Disclosed herein is an automatic analyzer that includes one or more pipetting probes for pipetting reagents or samples to be examined, one or more pipetting-probe-transferring means for transferring the probes and one or more washing tubs installed on the transfer paths of the probes and having structure permitting the probes to pass therethrough. The washing tub has washing-water-discharging orifices for discharging washing water and air-jetting orifices for jetting out air. | 02-12-2009 |
20090257918 | REACTION CUVETTE FOR AUTOMATIC ANALYZER AND METHOD OF SURFACE TREATMENT FOR REACTION CUVETTE - The present invention provides reaction cells capable of maintaining stable analytical performance by preventing bubble adhesion and reducing sample carryover even if the amount of sample liquid for a single test is further reduced in the future. The invention further provides an automatic analyzer that uses the reaction cells and a method for enhancing the hydrophilicity of the inner surfaces of the reaction cells. According to the invention, a reaction cell has a first electrode inserted thereinto and a second electrode disposed on the bottom side of the reaction cell. A voltage is applied between the first electrode and the second electrode to cause electric discharge between the electrodes. This allows for enhancing only the hydrophilicity of the bottom inner surface and the four bottom corners of the reaction cell to which large bubbles adhere easily. | 10-15-2009 |
20090306300 | Cell Made of Polymers for Spectra Measurement and Method for Producing the Same - This invention provides a cell made of polymers for spectra measurement while inhibiting a decrease in a molecular weight of resin caused by discharge treatment and having a stable hydrophilic modified surface. The hydrophilic resin cell is prepared by providing a polymeric resin cell between the two opposing electrodes, applying an electric field to a region between the above opposing electrodes under a nitrogen atmosphere with a pressure close to the atmospheric pressure to generate an electric discharge, and exposing the cell subjected to discharge treatment with a gas including oxygen. | 12-10-2009 |
20110223066 | AUTOMATIC ANALYSIS DEVICE - There is provided a high-accuracy automatic analysis device achieving both of measurement in a wide concentration range and high sensitivity at a low concentration. The signals of a plurality of wavelengths λ | 09-15-2011 |
20110300035 | AUTOANALYZER AND PIPETTING NOZZLE FOR AUTOANALYZER - There is provided a highly reliable autoanalyzer less liable to sample and reagent carry-over and capable of preventing contamination and precisely pipetting samples and reagents. Using a sample pipetting nozzle | 12-08-2011 |
20120020836 | PIPETTING NOZZLE FOR AUTOANALYZER, METHOD FOR PRODUCING SAME AND AUTOANALYZER USING SAME - In an autoanalyzer for analyzing samples, such as urine and blood, analytical and measured values are prevented from being affected by carry-over caused by the repeated use of a pipetting nozzle. A molecular layer for inhibiting the adsorption of biological polymers is formed by coating surfaces of the pipetting nozzle with a polyethylene glycol derivative chemisorbed thereto, thereby reducing carry-over caused by the pipetting nozzle. | 01-26-2012 |
20130064737 | AUTOMATIC ANALYZER - Disclosed is an automatic analyzer designed so that when it discharges a sample into an empty reaction vessel, the analyzer dispenses the sample without bringing a distal end of a sample probe into contact with a bottom surface of the reaction vessel and can thereby dispense the sample with stable dispensing accuracy in addition to extending lives of the sample probe and the reaction vessel. | 03-14-2013 |
20130171025 | Dispensing Nozzle for Autoanalyzer, Autoanalyzer Equipped with the Nozzle, and Method for Producing Dispensing Nozzle for Autoanalyzer - In an autoanalyzer for analyzing a specimen such as urine and blood, protecting a measurement value of analysis from influence of a dispensing nozzle repeatedly used. For this purpose, a phosphonic acid derivative or a phosphoric acid derivative is chemically adsorbed on the surface of the dispensing nozzle. In this manner, a molecular layer for suppressing adsorption of biopolymers or adhesion of a specimen per se is formed on the nozzle surface to prevent accuracy of analysis from being influenced. | 07-04-2013 |
20130259745 | AUTOMATIC ANALYZER - The occurrence of splash of a sample or a reagent from a nozzle tip is prevented during shifting of a dispensing mechanism. An automatic analyzer includes a nozzle for sucking liquid to be dispensed; a pump for allowing suction of the liquid into the nozzle and generating pressure variations; a pipe line connecting the nozzle with the pump; and a shifting mechanism for shifting the nozzle in horizontal and vertical directions. In the automatic analyzer, the pipe line is at least partially composed of a flexible tube. The flexible tube has an upward or downward convex bending portion in the middle thereof. The convex bending portion changes in position and shifts along with the shifting mechanism at a nozzle side. If the nozzle is shifted horizontally, a value obtained by subtracting a vertical distance between the top of a convex portion of the flexible tube and the uppermost portion of the nozzle from a vertical distance between the tip portion of the nozzle and the uppermost portion of the nozzle is a value ranging from −30 mm to 130 mm. | 10-03-2013 |
