1. A sampler for taking samples from a molten metal bath, the sampler comprising:
a carrier tube having an immersion end;
a sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening;
an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, and the opening is configured to receive the molten metal from the inflow conduit;
a sampler head, wherein the sample chamber assembly and the second end of the inflow conduit are at least partly arranged in the sampler head; and
a metal bushing, the metal bushing extending into the housing and directly coupling the inflow conduit to the sample chamber assembly.
 
20. A sampler for taking samples from a molten metal bath, the sampler comprising:
a carrier tube having an immersion end;
a sample chamber assembly comprising:
a cover plate; and
a housing comprising an immersion end having an opening; and
a clamp engaging the cover plate and the housing to prevent separation of the cover plate and the housing from each other and maintain the sample chamber assembly in an assembled state, wherein in the assembled state, the cover plate and the housing form a cavity longitudinally therebetween;
an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, and the opening is configured to receive the molten metal from the inflow conduit;
a sampler head, wherein the sample chamber assembly and the second end of the inflow conduit are at least partly arranged in the sampler head; and
a metal bushing, the metal bushing extending into the housing and coupling the inflow conduit to the sample chamber assembly.
