Patent number: 10639625Abstract: A pipette tip includes a body and projections. In the body, a flow passage in which liquid from the syringe flows and an ejection opening that ejects the liquid, which has flowed through the flow passage, to the outside are formed. The ejection opening is formed in a distal end portion. The projections are provided on the distal end portion and protrude from a region around the ejection opening in the ejection direction of liquid. The projections are partially disposed around the central axis of the body. Even in a case where a residual droplet adheres to the ejection opening, the residual droplet does not adhere to an injection opening of a sample container, because the projections guard a region around the residual droplet.Type: GrantFiled: March 23, 2018Date of Patent: May 5, 2020Assignee: FUJIFILM CorporationInventors: Toshiaki Kuniyasu, Toshihito Kimura, Tomonori Nishio, Kazuteru Nishijima

Publication number: 20110229977Abstract: Testing of a test article based on a color development state of a test area is achieved in an easy manner. A sample is deposited on a spreading layer of a test piece, and the test piece is loaded in a loading port of a chromatographic analysis apparatus. After a preset time has elapsed, color development states of the test area and a control area in an observation window are read as an image. A preprocessing unit applies preprocessing to the image, and then, spatial frequency components of the image are calculated. Then, pattern information is generated based on the spatial frequency components, and the pattern information is displayed on an information output unit.Type: ApplicationFiled: February 2, 2011Publication date: September 22, 2011Applicant: FUJIFILM CORPORATIONInventors: Tomonori NISHIO, Akira ITO, Mitsuaki UCHIDA, Yasunori OHTA, Katsuya INANA
