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. 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. In this method, the removable conformal an liner of the present invention with a flexible or semi-rigid body is placed into a centrifuge container. Once inside the container, the liner body conforms to the shape of the interior cavity of the container. The step of placing the liner may include def…
