An adjustable-volume, sealed chemical-solution-confinement vessel for enclosing the inner bottom surface of the chemical-solution-confinement vessel within a sealed chamber. The chemical-solution-confinement vessel comprises a well-shaped base into which a complementarily-shaped lid is inserted. The lid can be inserted to a first position, in order to create a small volume sealed chamber above the inner bottom surface of the chemical-solution-confinement vessel, and can be retracted to a second position in order to create a larger volume sealed chamber above the inner bottom surface of the chemical-solution-confinement vessel. The lid may contain a port or aperture for introducing a fluid or material into the sealed chamber.

[ What is claimed is:] [1.]1. An adjustable-volume, sealed chemical-solution-confinement vessel comprising:a base with a continuous side wall, the base and continuous side wall together forming a well shaped, open container, the continuous side wall having an external and an internal side, the base having an internal and an external side;a plurality of raised, circumferential members on the internal side of the continuous side wall, the circumferential members coplanar with planes parallel to the base; anda lid complementarily shaped to fit within the continuous side wall, the lid having a flared outer lower edge that snugly fits in circumferential depressions adjacent the circumferential members, pressure of the lower edge of the lid against one of the circumferential members forming a seal, the lid movable, in a direction approximately perpendicular to the plane of the base, so that sealed chambers of increasing volumes are formed when the flared outer lower edge of the lid fits in each of the circumferential depressions at increasing distances from the base.
