Abstract: The turret (1) in accordance with the invention has two rotation axes, a vertical axis (A) and a horizontal axis (B); it includes a weapon (2), aiming means (3) and two motors, one part (10) of the turret (1) being turned about the vertical axis (A) by the first motor and the weapon (2) and the aiming means (3) being turned about the horizontal axis (B) by the second motor; it is characterized in that an additional element (6) is turned to coaxially about the vertical axis (B) by a third motor that is specific to it. The turret (1) is thus equipped with two motors rated to turn on the one hand the mobile part (10) of the turret about the vertical axis (A) and on the other hand the weapon (2) and the aiming means (3) about the horizontal axis (B). The turret (1) is thus rated optimally; the additional element (6) has a dedicated motor that is also rated optimally and can be of different powers depending on the inherent characteristics of this element (weight, inertia, etc).

Abstract: The invention relates to an injection port for analysis appliances, said injection port (10), when fitted correctly on an analysis appliance, forming an access line which leads to an analysis chamber of the analysis appliance and through which it is possible to guide the cannula of a sample injector containing a sample to be analysed, characterized in that the injection port comprises at least one elastic valve element (24) which can be opened and closed in a controlled manner and by means of which the access line to the analysis chamber can be sealed off both in the absence of a cannula and also when a cannula is guided through the injection port. The invention further relates to an analysis appliance provided with a corresponding injection port, and to a device for actuating the injection port.
