Reaction vessel for performing investigation of biological fluid i.e. blood, has perforation projection formed into reservoir when moving closure stopper from first closure position into second closure position

摘要

The vessel (1) has a closure stopper (2) provided in a first closure position in which a reservoir is closed and in a second closure position in which the reservoir is opened for accommodating disposal reagent. A perforation projection is formed into the reservoir when moving the closure stopper from the first closure position into the second closure position. A material of the closure stopper is selected from a group consisting of polyethylene, polystyrene, polypropylene, polyamide, acrylic, polycarbonate, thermostable plastic or mixtures. Independent claims are also included for the following: (1) a closure stopper (2) an in-vitro method for analyzing biological specimen i.e. blood sample.
