Abstract
A plurality of centrifugation vials having a common base form a cluster tray suitably shaped for receipt by a standard multiwell or cluster tray carrier for a centrifuge. The tray base is segmented into individual vial bases to facilitate separation of a given vial from the cluster tray if desired. The bottom surface of each vial directly under the vial's interior chamber is recessed from the bottom supporting surface of the cluster tray to avoid scuffing or scratching. A skirted snap-plug cap is also provided for improved sealing means and to decrease the risk of contamination upon opening and closing of the vial. The vials and cluster trays thereof are preferably formed from transparent polymeric materials which can support anchored cell growth.
