Patent number: 10537891Abstract: A meniscus reducing member for use in a vessel for containing a liquid may include a physical surface feature overlying at least a portion of an interior surface of the vessel. The physical surface feature may have first and second inner surfaces that are generally parallel and at least a third surface extending between the first and second surfaces. The first inner surface, second inner surface and third surfaces may be configured to physically alter a receding contact angle between the liquid and the physical surface feature. A coating material may be applied to at least one of the surfaces of the physical surface feature to chemically alter the receding contact angle between the liquid and the coated surface whereby the receding contact angle formed between the liquid and the meniscus reducing member is between about 90 degrees and less than 180 degrees.Type: GrantFiled: March 12, 2018Date of Patent: January 21, 2020Assignee: STEMCELL TECHNOLOGIES INC.Inventors: Oliver Egeler, Steven Woodside

Patent number: 9062283Abstract: The present application is directed to methods of improving cell culture vessel assays. In one aspect the application is directed to a method of reducing the curvature of the meniscus comprising applying a coating material to the interior wall of the vessel, wherein the coating material provides a receding contact angle of about 90 degrees with aqueous solutions and culture media. In another aspect, the application is directed to a method of labeling cells in a first solution by generating droplets of a second solution containing at least one cell-labelling agent and allowing the droplets of the second solution to contact the surface of the first solution.Type: GrantFiled: February 26, 2008Date of Patent: June 23, 2015Assignee: STEMCELL TECHNOLOGIES INC.Inventors: Steven Woodside, Jason Dowd, Gary Dossantos, Oliver Egeler

Publication number: 20070020151Abstract: A pipette tip holder is provided for holding a plurality of pipette tips in an automated pipette machine. The pipette tip holder includes a container that defines a cavity. There is at least one vertical divider in the cavity that divides the cavity into a plurality of segregated compartments. The pipette tip holder further includes a tip support member. The tip support member is connected to the container, The tip support member defines a plurality of apertures. The apertures are sized to receive and suspend said pipette tips in the cavity. Each aperture is generally aligned with one of said compartments. The at least one vertical divider is sized and positioned to inhibit contact between bottom portions of adjacent pipette tips.Type: ApplicationFiled: July 20, 2005Publication date: January 25, 2007Inventors: Steven Woodside, Terry Thomas, Graeme Cross, Andrew Angus
