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.
