The inventive probe (10) for taking samples of an analyte located in a fluid medium has a membrane which closes the probe (10) to the outside and which is permeable to the analyte, a flow-through cell which is configured behind the membrane, a probe part (14) with at least one incoming line and one outgoing line leading to or from the flow-through cell and a membrane support (160), which together with the membrane, forms a replaceable unit of the probe part (14) with the incoming line and outgoing line.
