ABSTRACT:
A sample cup for use in holding a sample for spectrochemical analysis consists of a main cell member which is cup-shaped and has a closed top surface. Located on the top surface is a venting means which includes a beam-like section of a given thickness extending along the top surface near the center. The beam is surrounded by a thinner area integrally fabricated with the top surface. Extending upwardly from the surface of the beam is a post which when pushed downwardly crosses the cantilever beam to rupture the thin area thus creating a venting path for pressure equalization. The cantilever beam automatically returns due to spring action to its original position thus preventing excessive material from escaping from the hollow confines of the sample cup.
