A sampler for taking samples from a molten metal bath, particularly a molten steel bath, the sampler comprising: - a carrier tube having an immersion end; - a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, wherein the housing includes: - an immersion end having a first opening for an inflow conduit and an opposing end having a second opening for a gas coupler; and - a first face extending between the immersion end and the opposing end, the first face having a first depression proximate the immersion end and a second depression, the first depression being an analysis zone and the second depression being a ventilation zone, a portion of the analysis zone overlying a distribution zone which is in direct flow communication with the first opening and configured to receive the molten steel from the inflow conduit, - wherein a depth of the analysis zone is greater than 1.5 mm and less than 3 mm, - wherein the cover plate and the housing are configured to be assembled together to form a sample cavity, wherein the sample cavity extends from the immersion end towards the opposing end of the housing along a longitudinal axis X and includes the distribution zone, the analysis zone and the ventilation zone, such that an analysis surface of a solidified steel sample formed within the sample cavity lies in a first plane, and - wherein the first and second openings (20, 33) are spaced apart from the first plane, characterized in that a cross-sectional area of the inflow conduit taken along the plane perpendicular to the longitudinal axis X is between 0.5 and 2 times of a cross-sectional area of the analysis zone and between 0.20 and 0.70 times of a cross-sectional area of the distribution zone. - a carrier tube having an immersion end; - a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, - an immersion end having a first opening for an inflow conduit and an opposing end having a second opening for a gas coupler; and - a first face extending between the immersion end and the opposing end, the first face having a first depression proximate the immersion end and a second depression, the first depression being an analysis zone and the second depression being a ventilation zone, a portion of the analysis zone overlying a distribution zone which is in direct flow communication with the first opening and configured to receive the molten steel from the inflow conduit, - wherein a depth of the analysis zone is greater than 1.5 mm and less than 3 mm, - wherein the cover plate and the housing are configured to be assembled together to form a sample cavity, wherein the sample cavity extends from the immersion end towards the opposing end of the housing along a longitudinal axis X and includes the distribution zone, the analysis zone and the ventilation zone, such that an analysis surface of a solidified steel sample formed within the sample cavity lies in a first plane, and - wherein the first and second openings (20, 33) are spaced apart from the first plane, - wherein a depth of the analysis zone is greater than 1.5 mm and less than 3 mm, - wherein the cover plate and the housing are configured to be assembled together to form a sample cavity, wherein the sample cavity extends from the immersion end towards the opposing end of the housing along a longitudinal axis X and includes the distribution zone, the analysis zone and the ventilation zone, such that an analysis surface of a solidified steel sample formed within the sample cavity lies in a first plane, and - wherein the first and second openings (20, 33) are spaced apart from the first plane,
