Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
Cuvette matrix with at least one line or row of cuvettes, placed in tray with space for at least one cuvette matrix, characterized in, that at least a part of adjacent cuvettes (2) of the matrix are connected with one another by flexible connecting elements (3) that permit the distance between the cuvettes to change a little and that each cuvette has a lower part that can be pushed into a corresponding aperture and that the tray has substantially a rectangular frame with at least one aperture matrix, corresponding the cuvette matrix, with an aperture for each cuvette of the matrix (8), where the cuvette (2) can be settled, the aperture comprising a flexible clamping element (9) that keeps the cuvette, settled in the aperture, in place with help of the friction.
Claim 2
Dependent Claim
132 words
Cuvette matrix with at least one line or row of cuvettes, placed in tray with space for at least one cuvette matrix, characterized in, that at least a part of adjacent cuvettes (2) of the matrix are connected with one another by flexible connecting elements (3) that permit the distance between the cuvettes to change a little and that each cuvette has a lower part that can be pushed into a corresponding aperture and that the tray has substantially a rectangular frame with at least one aperture matrix, corresponding the cuvette matrix, with an aperture for each cuvette of the matrix (8), where the cuvette (2) can be settled, the aperture comprising a flexible clamping element (9) that keeps the cuvette, settled in the aperture, in place with help of the friction.
Claim 3
Dependent Claim
25 words
Cuvette matrix as claimed in claim 1, characterized in, that it is possible to remove one cuvette or more from the matrix at a time.
Claim 4
Dependent Claim
23 words
Cuvette matrix as claimed in claim 1 or 2, characterized in, that the cuvette is removable by breaking the flexible connecting element (3).
Claim 5
Dependent Claim
28 words
Cuvette matrix as claimed in any of the claims 1 - 3, characterized in, that the connecting element is a stem (3) connecting the cuvettes with one another.
Claim 6
Dependent Claim
54 words
Cuvette matrix as claimed in claim 4, characterized in, that the stems (3) are in each line or row of cuvettes at a distance from the centre line of the line or row of cuvettes, in successive spaces at a different distance from the centre line or on opposite sides of the centre line.
Claim 7
Dependent Claim
24 words
Cuvette matrix as claimed in claim 5, characterized in, that the stems (3) in successive spaces are on opposite sides of the centre line.
Claim 8
Dependent Claim
29 words
Cuvette matrix as claimed in any of the claims 1 - 6, characterized in, that there is a projecting flange (5) on the outer surface of the cuvette (2).
Claim 9
Dependent Claim
43 words
Cuvette matrix as claimed in any of the claims 1 - 7, characterized in, that the clamping element includes at least one flexible finger (9) placed on the wall of the aperture, that presses the cuvette against the other wall of the aperture.
Claim 10
Dependent Claim
16 words
Cuvette matrix as claimed in claim 8, characterized in, that the finger (9) is horizontally flexible.
Claim 11
Dependent Claim
21 words
Cuvette matrix as claimed in claim 8 or 9, characterized in, that there is only one finger (9) for each cuvette.
