  • Removable conformal liners for centrifuge containers
    Patent number: 7128838
    Abstract: A removable conformal liner for a centrifuge container is described. The liner has a flexible or semi-rigid body with an opening for introducing a sample. When the liner is inserted into an internal cavity of a centrifuge container, the body of the liner conforms to the interior cavity. The liner body may be made of a material that is sufficiently resilient to allow a reversible deformation of the body by folding, twisting, collapsing, rolling, or pleating.
    Type: Grant

    Date of Patent: October 31, 2006
    Assignee: Beckman Coulter, Inc.

The liner body may be made of a material that is sufficiently resilient to allow a reversible deformation of the body by folding, twisting, collapsing, rolling, or pleating. Also disclosed is a centrifuge container assembly, including a container suitable for centrifuging and a removable liner with a flexible or semi-rigid body placed into the container. The centrifuge container assembly of this invention may also have retaining-means for retaining the liner in a fixed position within the container. Also provided by the present invention is a method for separating solids from suspensions by centrifugation.

  • Percoll and sugar self-forming density gradient
    Patent number: 5985037
    Abstract: A stable self-forming density gradient is created by applying a centrifugal field to a solution that contains 27-33% Percoll (v/v) and 36-44% sugar (w/w). This density gradient is stable for several hours, allowing separation of low sedimentation particles, such as subcellular particles.
