A foreline for a vacuum pump with an inlet connectable to e.g. a vessel to be evacuated and an outlet connected to and inlet of the vacuum pump to evacuate the vessel. Thereby, the foreline further comprises a discharge line with a first end and a second end, wherein the first end comprises an opening and the second end comprises a solid material trap. The second end is arranged outside the foreline. The first end is arranged within the foreline between the inlet and the outlet and the opening is open towards the inlet of the foreline such that incoming solid material is collected by the opening, discharged through the discharge line and caught in the solid material trap.
