Abstract
A feeder unit, which is used for selectively charging an analyzing apparatus with liquid or gaseous sample-, reference- or cleaning media, comprises a sample inlet and a feeder part hinged on the feeder unit at one end. The feeder part contains an intake passage for the cleaning medium to be entered, the sample inlet having a flexible feeder funnel cooperating with a washing element which is attached to the feeder part and can be introduced into the funnel. The feeder part is configured as a cover flap swinging around a fixed pin. The intake passage for the cleaning medium opens into the washing element and is also used for delivering liquid and gaseous reference media. The washing element is located on a support which is elastically attached to the cover flap, and fits into the flexible funnel when the cover flap is closed.
