Abstract
In conventional devices for feeding an analyzing apparatus with different media, comprising a feeder unit with fittings for the media to be introduced, the individual media travel different paths between the input opening and the measuring chambers, which will result in different conditions of measurement for calibrating media and sample media. The invention eliminates this drawback by providing the feeder unit 1 with input elements 6, by placing the sample input opening 4 on a supporting piece 3 which may be moved by a control unit 17, and by providing that each input element 6 may be brought into sealing contact with the sample input opening 4 subsequent to a rotatory motion of the supporting piece 3.
