APPARATUS AND METHODS FOR PROCESSING BIOLOGICAL MATERIAL

摘要

A sedimentation chamber (10, 84) for concentrating cells in a suspension is described. In one embodiment, the chamber comprises a housing defining a substantially spherical inner chamber (26, 88); and a port (28, 92) in the housing communicating with the inner chamber. The port includes a resealable closure (40) and the inner chamber comprises at least one of (i) a cell-receiving pocket (30) positioned generally opposite the port and (ii) a defined gas collection region (94) generally in proximity to the port. In another embodiment, the chamber comprises a housing defining an inner chamber (26, 88) having a chamber surface; a port (28, 92) in the housing communicating with the chamber; a defined cell collection region (30) in the chamber surface generally opposite the port; and a defined gas collection region (94) on the chamber surface generally in proximity to the port.
