Abstract

In its initial position an input opening of a sample input device provides a seal against a funnel element which is directly connected to a feed pipe delivering standard media and to a valve-controlled air supply, and which has a feed opening cooperating with the input opening. Thus, in the initial position of the sample input device, the input opening and the feed opening at the funnel element together are part of a closed path for the additional media required for measurement and cleaning purposes, which will simplify the overall design of the apparatus.
