Abstract: A system of flow-through cells is obtained by assembling a body with a base plate. The body has a first spring element and a first stop, disposed on opposite end sections of the body, at least one second spring element and a corresponding second stop, disposed on opposite faces of the body, and at least one support element and at least one retaining element, which are adapted for the exact positioning of the body in the receiving openings of a support in three directions.

Abstract: An integrally built, linear array of cuvettes is made of a plastic material. This array comprises a plurality of cuvettes arranged along a straight line in an array, each cuvette in the array having the same shape and dimensions, and neighboring cuvettes being connected to each other by a single web. Each of the single webs has a curved shape. The symmetry axis (Y-Y) of every cuvette forming part of said array of cuvettes lies substantially in one and the same plane (A-A) which is a symmetry plane of said cuvette array. The upper part of at least one intermediate cuvette which is located between a first cuvette located at one end of the cuvette array and a second cuvette located at the opposite end of the cuvette array is connected by a first single web to the upper part of a neighboring cuvette lying on one side of said intermediate cuvette and is connected by a second single web to the upper part of a neighboring cuvette lying on the opposite side of said intermediate cuvette.

Abstract: An integrally built, linear array of cuvettes is made of a plastic material. Every cuvette of the array has the same shape and dimensions. Neighboring cuvettes are connected to each other by a single web. Each of the single webs has a curved shape and each cuvette has means forming integral part thereof and serving for accurately positioning the cuvette into an opening of a cuvette holder and means for removably connecting the cuvette to the cuvette holder. Each cuvette has an upper chamber and a lower chamber having a common symmetry axis passing through the centers of both chambers. Each of the upper and lower chambers has a substantially cylindrical shape. The cross-section of the upper chamber at the central part thereof is larger than the cross-section of the lower chamber. The lower chamber has an open lower end. The upper chamber has an open top end and an annular bottom wall having a central circular opening which connects the upper chamber with the lower chamber.

Abstract: The invention relates to a system of flow-through cells that is obtained by assembling a body (11) with a base plate. The body (11) comprises the following elements which are adapted for the exact positioning of the body in the receiving openings of a support in three directions (Y, Y, Z direction): (a) a first spring element and a first stop, disposed on opposite end sections of the body (11), (b) at least one second spring element and a corresponding second stop, disposed on opposite faces of the body (11), and (c) at least one support element and at least one retaining element.
