Abstract
Abstract A reaction vessel comprises a first body (1) defining an open cavity adapted to receive a portion of a second body (21). The surface of the cavity comprises a first portion (2) adjacent the exterior of the cavity which conically tapers inwards with an included angle of about 6° and a second portion (3) which conically tapers inwards with an included angle of about 90°. The external surface of the second body (21) includes a first portion (22) which conically tapers with an included angle of about 6° and a second portion (23) with an included angle of about 90°. The surface (22) of the second body (21) carries a plurality of short projections (26). The shape of the second body substantially matches that of the cavity in the first body whereby when the one is inserted into the other a capillary space having a thickness of about 0.05mm is defined between them. The reaction vessel is prepared for use by immobilizing one or more reactants on one or more of the surfaces (2) and (22).
