Abstract

1381020 Piston in centrifugal separator container BECTON DICKINSON & CO 28 Dec 1972 [25 April 1972] 04350/74 Divided out of 1381019 Heading B2P The subjectmatter of this Specification is identical with that of the parent Specification but the invention is directed to a piston for use in an apparatus for separating blood into light and heavy components by centrifugation and comprising a body portion having sealing means formed around its periphery, a rigid tubular sleeve mounted in the body portion, and normally closed valve means incorporated in the piston and arranged to open for passing fluid through the piston when there is a fluid pressure differential between the two sides of piston.
