Patent number: 5441895Abstract: A stack of a plurality of substantially identical cup-like vessels pre-incorporated with reagent on the inside, each of the vessels occupying at least about 50% of the depth of the next adjacent vessel to maximize stacking density. Because the pre-incorporated reagent overlaps the occupied depth portion of the vessel and therefore runs a risk of being dislodged, the wall of the vessel is constructed to provide a gap between the inside surface bearing the reagent, and the outside surface of the occupying, nested vessel, that is at least 0.025 mm.Type: GrantFiled: December 7, 1993Date of Patent: August 15, 1995Inventors: Raymond F.

Patent number: 5143849Abstract: A method for automatically adjusting a dispensing tip from a surface onto which liquid is to be dispensed, a proper distance that precludes the dispensing stream from puddling up, or from breaking apart. The method features the formation on the tip of a meniscus of a nominal small volume and advancing the tip and meniscus until the surface is contacted. The resulting decrease in pressure in the tip is measured, to trigger the tip to stop its advance and to start dispensing. In circumstances wherein the contacted surface is hydrophobic so as to ideally require a meniscus depth greater than the nominal depth, the tip is retreated from the surface, during dispensing, to the ideal depth.Type: GrantFiled: March 21, 1991Date of Patent: September 1, 1992Assignee: Eastman Kodak CompanyInventors: James V. Barry, Raymond F. Jakubowicz, J. Eric Hamann

Patent number: 5073342Abstract: There is disclosed a simplified transfer mechanism that minimmizes both the number of moving parts needed, and the shapes of those parts. An L-shaped pusher blade is mounted to move in and out of a first station such as at an incubator so as to be effective to move a test element from the first station to two or more subsequent stations.Type: GrantFiled: January 5, 1989Date of Patent: December 17, 1991Assignee: Eastman Kodak CompanyInventors: Johannes J. Porte, Raymond F. Jakubowicz

Patent number: 4593837Abstract: There is disclosed a pipette useful with disposable tips, comprising a plurality of differently-sized pistons and a piston chamber for each piston. Each piston chamber has a vent passageway extending to the exterior surface of the pipette. The pipette is improved in that the mounting means for mounting a disposable tip comprises, not one surface, but a plurality of differently-sized surfaces. Furthermore, the vent passageway for all but the smallest piston chamber exits at a location in between the mounting surface for the tip of that particular piston chamber and the next smaller mounting surface, whereby the larger disposable tips seal over the vent passageways of the smaller disposable tips.Type: GrantFiled: March 15, 1985Date of Patent: June 10, 1986Assignee: Eastman Kodak CompanyInventors: Raymond F. Jakubowicz, Stuart G. MacDonald
