Abstract

A stopper for a centrifuging bottle, esp. for the separation of serum from blood, automatically dispenses a predetermined amount of beads or granules of solid matter into the bottle. At its upper end it is a normally closed stopper and it contains the solid matter in an inner chamber with a seal at the bottom. When a predetermined speed of revolution has been reached, the centrifugal force opens the seal and the solid matter is emptied. The sealing force of the hinged bottom cover is set at a predetermined value. The inner chamber contains a synthetic granulate serving as a centrifuging auxiliary, in a quantity of about 0.5 g and with a particle size of 2-3mm. The closing force of the seal is equiv. to a centrifugal force acting at about 1,500 r.p.m in a machine for separating serum. When opened the seal is still retained by the stopper, the closing force being derived from its resilience.
