Patent ID: 7794668

Claim:
A reaction vessel for performing chemical reactions, comprising: (a) a single-piece body made of a polymeric material, the body defining a reaction chamber, a connection channel, and a discharge channel, each having an interior space; said body having an outer shape that corresponds to the inner shape of a corresponding cavity of a reaction block, said body being thereby adapted to be inserted into said cavity; (b) the reaction chamber and the discharge channel each having an upper end with an opening therein; (c) the reaction chamber and the discharge channel each having a bottom portion with an orifice therein; (d) the reaction chamber and the discharge channel each tapering from the open upper end toward the bottom portion with decreasing cross-sectional area; and (e) the connection channel extending from the orifice of the bottom portion of the reaction chamber to the orifice of the bottom portion of the discharge channel and thereby fluidically connecting the interior space of the discharge channel with the interior space of the reaction chamber, said connection channel having a circular cross-section which decreases in diameter from the orifice of the bottom portion of the reaction chamber to the orifice of the bottom portion of the discharge channel, wherein the opening at the upper end of the reaction chamber and the opening at the upper end of the discharge channel are interconnected by a channel, hole or groove which fluidically connects the interior of the reaction chamber with the interior of the discharge channel.
