Abstract Microcuvette set which comprises several cuvettes (5) in a matrix form, arranged so as to be handled as one whole unit. The frame portion of the microcuvette set (1) consists of a preferably rectangular frame portion (2) designed so that two or more cuvette-set components (3) can be attached to it in the longitudinal or transverse direction one after the other. Each of the said cuvette-set components (3) consists of several cuvettes (5) disposed in a line or matrix form and connected to each other or attached together by means of a support plate (4), and the middle portion of the frame portion (2) is open at least within the area covered by the cuvettes (5) in the cuvette-set components (3). The microcuvette set (1) comprises a rectangular locking frame (6), open at its middle portion at least within the area corresponding to the frame portion (2), which locking frame is arranged so as to be attached to the top face of the frame portion (2), e.g., by means of a friction joint, so-called snap-in joint, or by means of any other joint suitable for the purpose. Thereby, the ends of the support plates (4) of the cuvette-set components (3) fitted into the frame portion (2) remain between the top face of the frame portion (2) and the locking frame (6).
A microcuvette unit including a plurality of cuvettes arranged in matrix form comprising in combination: a lower frame member defining a first open area about its center and support surfaces about its periphery, an upper locking frame member defining a second open area about its center corresponding to said first open area of said lower frame member, said upper locking frame member being constructed so that its periphery will engage the lower frame member when mounted thereupon to attach said locking frame member to said lower frame member, said locking frame member further defining locking surfaces arranged to be in facing relation with said support surfaces of said lower frame member when said frame members are lockingly attached one to the other, and a plurality of matrixed cuvettes arranged on support plates having at their edges coupling means, said coupling means being configured to cooperate with said support surfaces of said lower frame member so that said plurality of said support plates are disposed in a predetermined orientation when mounted on said lower frame member, whereby upon assembly of said plurality of cuvette matrices and frame members said coupling means of said matrices are lockingly engaged between said members and said first and second central open areas of said frame members are at least of sufficient area to accomodate said cuvettes so that each cuvette in said assembly is upwardly open.
