The probe front part (1) side (5) turned away from the pointed end forms the bottom of the container part (4) during sampling, and narrows inwards in the direction running from the pointed end. The container part comprises a tube (4) of pref. circular cross-section. The front part (1) is joined to the pressure and tractive part (3) via a shaft (2) which can move backwards and forwards through a hole in the pressure and tractive part front section (3). The pressure and tractive part (3) front surface narrows inwardly in the direction of the front part (1). The shaft (2) has a stop part (7) at its upper end, by means of which the displacement movement of the front part from the pressure and tractive part (3) is restricted. |
