Abstract
A fillable sample taking element for handling a liquid sample has a conical end portion which defines an intake and discharge opening, which is adapted to be sealed by a conical valve member, which is provided with an actuating rod, which protrudes outwardly through the intake opening and is bare relative to said intake opening. The valve constitutes a gravity valve having a valve member (8) which is disposed in the interior of the sample taking element (3) in the tapering portion (13) thereof which is disposed above and tapers from the intake opening (6). The valve seat for that valve member has a surface which faces away from the intake and discharge opening. The outwardly protruding actuating rod (10) serves to unseat the valve member. The valve will be closed when the sample taking element is arranged with the intake and discharge opening at the bottom and/or under the action of an internal pressure in the sample taking element.
