Abstract

A gas-tight chemical reaction vessel for the chemical analysis of an intractable material such as glass. The reaction vessel comprises a body having at least two concentric chambers, one of which is adapted to contain a reagent, at least one other of which is adapted to receive a sample cap which in turn is adapted to receive a sample. The reaction vessel has a sealing member for sealing the chambers of the body and a cap for securing the sealing member against the body. The body, sealing member and sample cap are made of a material, desirably polytetrafluoroethylene, which is chemically inert to the reagents.
