Cell for measuring cork permeability

摘要

The cell (30) has a gas-tight collection plate (29) assembled with a sample holder in a watertight manner so as to cover an output opening (152). An axial cylindrical pipe (100) of the holder includes an interior bearing surface i.e. revolution surface, comprising a small diameter section whose diameter is lower than that of other sections of the bearing surface. A truncated surface portion of the pipe converges toward the small diameter section, where a bearing surface portion is divergent on a side opposed from the small diameter section. An independent claim is also included for a stopper support and test cell assembly.
