Patent number: 11130983Abstract: Aspects of the present disclosure include sample preparation cartridges including a frame that includes a plurality of wells integrated therewith, where the plurality of wells have a closed bottom and an open top. The frame further includes an opening within the frame having a reaction vessel (RV) or RV cap removably disposed therein, where the plurality of wells and the opening are linearly arranged relative to each other. Also provided are sample preparation cartridges that include a frame, two or more cartridge separation projections on a top side of the frame, and two or more cartridge separation projections on a bottom side of the frame. The cartridge separation projections separate the cartridge and a different cartridge when the cartridge and different cartridge are stacked. Methods of using the sample preparation cartridges, as well as nucleic acid sample preparation units that include the sample preparation cartridges, are also provided.Type: GrantFiled: March 15, 2017Date of Patent: September 28, 2021Assignee: Abbott Molecular Inc.Inventors: Timothy P.

Patent number: 8409528Abstract: A reaction vessel with a bottom drain opening supporting a selected unpressured head of fluid by the surface tension of the fluid. A device processing zone includes a support for spaced rows of reaction vessels, passages communicating with their drain openings of supported vessels, and a pressure source for selectively draining fluid through the drain openings. Generally horizontal bar magnets are supported for selected vertical movement between the vessel rows. A dispensing head has X discharge openings selectively positionable over X selected reaction vessels. A metering pump mechanism selectively meters X a selected quantity of fluid a bulk supply (where X is at least four), and selectively pumps the metered selected quantities through the drain openings to the selected reaction vessels. Methods of drawing fluid from the vessels using the pressure source, and moving the magnets to form a pellet of analyte are also included.Type: GrantFiled: June 10, 2004Date of Patent: April 2, 2013Assignee: Abbott LaboratoriesInventors: Scott Safar, Stephen Herchenbach, Chadwick M.

Patent number: 6562298Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. One embodiment relates to a structure which comprises a process path. The process path comprises a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided. A first prime mover is operatively connected with the process path for moving a container holding the sample along the process path. A first pipetting system is operatively associated with the process path for introducing the sample to the container. A second pipetting system is operatively associated with the process path for introducing a reagent to the container. A device is operatively connected with the process path and is selectively engagable with the container for mixing the sample and the reagent in the container.Type: GrantFiled: April 23, 1999Date of Patent: May 13, 2003Assignee: Abbott LaboratoriesInventors: David C.

Patent number: 5856194Abstract: The embodiments disclosed relate to determination of an item of interest in a sample. In one method, a process path comprising a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided is provided. A container holding the sample is moved along the process path. The sample is introduced to the container. A reagent is introduced to the container. The sample and the reagent are mixed in the container. The container is selectively positioned in a selected one of the process step performance lane and the process step avoidance lane. The item of interest in the sample is determined based upon a reaction between the sample and the reagent.Type: GrantFiled: September 19, 1996Date of Patent: January 5, 1999Assignee: Abbott LaboratoriesInventors: David C.

Patent number: 5795784Abstract: Embodiments described herein provide methods of performing a process for determining an item of interest in a sample. In one embodiment, a container for holding the sample is accepted in a process lane where a process step is selectively automatically performed on the sample in the container. The process step is selectively automatically performed on the sample in the container. An effective length of the process lane is maintained constant while a physical length of the process lane is selectively varied.Type: GrantFiled: September 19, 1996Date of Patent: August 18, 1998Assignee: Abbott LaboratoriesInventors: David C.
