Abstract

A reaction vessel having a reaction chamber for holding a sample is fabricated by producing a housing having a rigid frame defining the minor walls of the chamber. The housing also defines a port for introducing fluid into the chamber. At least one sheet or film is attached to the rigid frame to form at least one major wall of the chamber. In preferred embodiments, two sheets or films are attached to opposite sides of the rigid frame to form two opposing major walls of the chamber, the major walls being connected to each other by the minor walls.
