A sampling unit for a concentrates preparation device comprises a movable rod 1403, a sampling chamber 1405, a sampling bore 1404, an axle sleeve 1407 and an isobaric chamber (1409, fig. 2). The movable rod is provided with a refreshing passage 1; the end 102 of the refreshing passage extends away from the handle 1406 and extends to the exterior cylindrical surface of the movable rod. A sample collected in the sample chamber is emptied via the refreshing passage, enabling the chamber to be refilled quickly. |
