摘要

The invention concerns a sampling device in which the boundary with the microbiologically contaminated environment takes the form of a sterile protective gas stream with "laminar air flow" characteristics underneath a housing bell (7); the connection point between the inner tube (11) and the sample tube (10) is at a point inside or just underneath the bell (7), with or without a fixed connection, and for automatic operation just underneath the bell (7) without a fixed connection.
