The metering casing defines a free end of the pipette whereat the metering casing forms an opening. The metering chamber has an opposite end lying opposite to the free end of the pipette and the opposite end of the metering chamber is delimited by an air-permeable retaining element. The retaining element is configured as a flexible filter defining a plane and having a back side facing away from the metering chamber. An air-permeable support core supports the filter at the back side thereof and is rigid transversely to the plane of the filter.
