  • Publication number: 20180200711
    Abstract: 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.

  • Patent number: 9062283
    Abstract: 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.

  • Patent number: 8409873
    Abstract: A method of pipetting comprises (a) providing a pipette tip holder having a plurality of segregated compartments and a tip support member for supporting a plurality of pipette tips in the pipette tip holder, the tip support member configured to support a single pipette in tip each segregated compartment; (b providing a plurality of pipette tips in the tip support member; (c) removing a first pipette tip from a first segregated compartment; (d) using the first pipette tip to complete a pipetting operation and placing the first pipette tip into a segregated compartment that has not contained a used pipette tip; (e) subsequently removing the first pipette tip from the segregated compartment and using the first pipette tip to complete another pipetting operation; and, (f) replacing the first pipette tip into the pipette tip holder, whereby the first pipette tip, when placed in the segregated compartment, is segregated in the pipette tip holder to reduce the possibility of a fluid from the first pipette tip contac

  • Publication number: 20080108047
    Abstract: The present invention is related to a method for separating a first population of cells from a second population of cells in a sample by discontinuous density gradient separation using dense particles to target the first population of cells and a density separation medium (DSM) that is at least about 0.001 g/cm3 higher than the density of the second population of cells.

  • Publication number: 20070020151
    Abstract: 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.
