An apparatus for extracting hot gas samples from a reaction vessel has at least one extraction probe having a gas-conducting inner tube and a filter, which succeeds the extraction probe. The filter is composed of a filter cup and a filter plug disposed therein. To permit a simple cleaning of the filter, the filter cup is formed by a diametrically enlarged, coaxial extension of the inner tube of the extraction probe and the filter plug is carried by a filter bottom, formed with blast nozzles. The nozzles are directed into the annular space formed between the filter cup and the filter plug.
