Universal closure device

A universal closure device for openings of sample containers having different cross-sections,

• the closure device comprising a shaft part with an outer surface, the shaft part extending in the direction of a longitudinal axis and having end sections spaced apart from one another in the direction of the longitudinal axis,
• and a plurality of sealing elements arranged in the area of the outer surface of the shaft part for applying against an inner casing surface of the sample container to be closed turned towards the longitudinal axis,
• the sealing elements arranged on the shaft part being arranged in series in a circumferential plane and in circumferential direction of the shaft part,
• wherein between the sealing element and the outer surface of the shaft part at least one supporting element is arranged which extends in between, and
• wherein the at least one supporting element is connected to at least one sealing element of the plurality of sealing elements and is connected to the shaft part.
