Abstract
Immersion samplers for the molten metals have a tubular sample chamber made of quartz glass or another refractory material with an inlet opening on the one end and an end, lying opposite to the inlet opening, which is mounted in a cardboard tube. An immersion sampler with a simple construction which makes possible sampling at low metal inlet velocity while preventing the formation of pinholes and pores in the sample, comprises an inlet opening for filling the sample chamber exclusively by ferrostatic pressure, the inlet having an open cross-sectional area compared to the cross-sectional area of the sample chamber directly behind the inlet opening, looking counter to the immersion direction, which is so sized that the filling velocity of the sample chamber based on ferrostatic pressure is at a maximum one fifth of the filling velocity at an inlet opening corresponding to the cross sectional area of the sample chamber directly behind the inlet opening. The inlet opening is also arranged in such a way that the incoming melt flows in at an angle greater than 0.degree. to the longitudinal axis of the sample chamber.
