Abstract

A mixing chamber designed for ready disassembly is described in which a generally spherical-shaped outer container encloses an inner sphere. Entry and exit openings are provided on opposite sides of the outer sphere, so that breath specimens pass through the chamber between the outer surface of the inner sphere and the inner surface of the outer sphere and undergo thorough mixing with low back pressure over a wide flow range. The interior volume can be increased by using a hollow inner sphere with an opening through the wall thereof to permit the inner sphere to fill with breath specimen also.
