- the predominant, axial length portion of the support assembly 15 is formed here by the wall portion 19 in its tubular or hollow cylindrical design.
- the latching arrangement 23 and / or the Centering assembly 26 may be provided for mutual support or fixation and for positioning aligned with each other.
- the closure device 3 is designed such that it is used as a conventional closure device in conventional receptacles.
- This closure device 3 is shown in FIGS. 2 to 4 and FIGS. 5 and 6.
- the collecting chamber 13 can also be lowered to a reduced pressure with respect to the ambient pressure, although this is not absolutely necessary.
- the sampling assembly 1 in this embodiment comprises the sample container 2 and the support assembly 15 and may also be referred to as Probenab fortunerschreibchen, sample collection or sample collection tube, in each of which a body fluid, in particular blood or urine, can be filled and stored for subsequent examination or analysis purposes.
