Abstract

The sampler according to the invention comprises a dish (6) which can rotate about an axis (20) inside a cover (15), this dish containing a filtering ring (11), the cover (15) communicating with a selection chamber (22) provided in a cap (21) on top of the cover (15), via a connector (30), with a conical outer surface, on top of a cylindrical tubular part provided with lateral orifices for bringing the orifice (19) into communication with the chamber (22). <IMAGE>
