Publication number: 20160216235Abstract: During filling of a capillary with an electrophoresis medium, this electrophoresis medium receptacle maintains a resting state, and the capillary and the electrophoresis medium receptacle are readily sealed. The electrophoresis medium receptacle is simple in shape, the electrophoresis medium receptacle is readily manufactured, and the electrophoresis medium is readily sealed. The amount of the electrophoresis medium sealed in the electrophoresis medium receptacle is brought into approximation without limit to the amount of the electrophoresis medium filling the capillary, minimizing dead volume. In this electrophoresis medium receptacle, a receptacle filled with an electrophoresis medium is maintained in a sealed state, and a septum which can be pierced by a capillary cathode end is provided. The pressure produced when the capillary cathode end pierces the septum in which the receptacle filled with the electrophoresis medium is sealed transports the electrophoresis medium into the interior of a capillary.Type: ApplicationFiled: June 30, 2014Publication date: July 28, 2016Inventors: Hitoshi MIYATA, Tomoyuki KATO, Toshiyuki SAKURAI, Motohiro YAMAZAKI

Publication number: 20160153936Abstract: The purpose of this invention has to do with being able to eliminate, using a small amount of an electrophoresis medium, air bubbles that get mixed in when loading an electrophoresis-medium container into a capillary electrophoresis device. This invention has to do with being able to simplify a positive-electrode-side channel in a capillary electrophoresis device by electrophoresing using only an electrophoresis medium on the positive-electrode side. This invention makes it possible to eliminate, easily and using a small amount of an electrophoresis medium, air bubbles that had become mixed in each time an electrophoresis-medium container was connected to the device. This invention also makes it easier to manage consumables and reduces the number thereof, making pre-electrophoresis preparation simple, and makes it possible to simplify and reduce the size of the device.Type: ApplicationFiled: June 11, 2014Publication date: June 2, 2016Inventors: Hitoshi MIYATA, Toshiyuki SAKURAI

Publication number: 20120043211Abstract: Provided is a capillary electrophoresis apparatus capable of avoiding electric discharge even when a conductive component is arranged near a cathode end of a capillary. The capillary electrophoresis apparatus of the present invention has a structure in which a spatial distance and a creeping distance between an electrode attached to the cathode end of the capillary and the conductive component are large even when the conductive component is arranged near the cathode end of the capillary. That is to say, the capillary electrode, which protrudes from a lower surface of the load header, penetrates through a space between the load header and an anti-evaporation film and further penetrates through a capillary hole formed on the anti-evaporation film to extend into a container. At least a portion exposed to the space between the load header and the anti-evaporation film of the capillary electrode is covered with an insulating member.Type: ApplicationFiled: April 8, 2010Publication date: February 23, 2012Inventors: Yasutaka Otsuka, Toshiyuki Sakurai, Tomohiro Shoji, Takeshi Ohura

Patent number: 7981267Abstract: An object of the present invention is to prevent a variation in heat dissipating effect of a capillary between a holder part and an oven, to improve reproducibility of migration time, and to reduce a variation of migration time among capillaries in a single electrophoresis run. A cylindrical wall is formed in an upper part of a septa that covers a container holding a solution, and the cylindrical wall surrounds a capillary hole through which a capillary penetrates. Accordingly, the capillary is prevented from being directly affected by wind generated between the septa and the oven.Type: GrantFiled: January 13, 2009Date of Patent: July 19, 2011Assignee: Hitachi High-Technologies CorporationInventors: Toshiyuki Sakurai, Takeshi Ohura
