Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
A cuvette matrix and tray therefor comprising at least one row of cuvettes flexibly interconnected one to the other by stems to allow for flexible play between each cuvette, each of said cuvettes being in the shape of a well of substantially cylindrical shape, each of said wells having an open top and a closed bottom, the cylindrical walls of each well being thickened at the upper portion thereof and slightly tapered at its lower portion to enable reception of said cuvette matrix by said tray, said tray for receiving said cuvette matrix comprising a frame having by rows of cuvette-receiving apertures having side walls adapted to frictionally receive and support each of said flexibly interconnected wells when said interconnected wells are inserted tapered end first into corresponding apertures of said tray, said apertures being defined by substantially rigidly disposed side walls defining said apertures, the side walls intersection to form each of said apertures, an inward wall of each of said apertures being severed to provide at least one flexibly deformable clamping element in each of said apertures for frictionally engaging and holding each of said wells.
Claim 2
Dependent Claim
188 words
A cuvette matrix and tray therefor comprising at least one row of cuvettes flexibly interconnected one to the other by stems to allow for flexible play between each cuvette, each of said cuvettes being in the shape of a well of substantially cylindrical shape, each of said wells having an open top and a closed bottom, the cylindrical walls of each well being thickened at the upper portion thereof and slightly tapered at its lower portion to enable reception of said cuvette matrix by said tray, said tray for receiving said cuvette matrix comprising a frame having by rows of cuvette-receiving apertures having side walls adapted to frictionally receive and support each of said flexibly interconnected wells when said interconnected wells are inserted tapered end first into corresponding apertures of said tray, said apertures being defined by substantially rigidly disposed side walls defining said apertures, the side walls intersection to form each of said apertures, an inward wall of each of said apertures being severed to provide at least one flexibly deformable clamping element in each of said apertures for frictionally engaging and holding each of said wells.
Claim 3
Dependent Claim
46 words
The cuvette matrix and tray as in claim 1, wherein a peripheral shoulder is provided on each of said wells between the thickened upper portion and said lower tapered portion, and wherein stop means is provided in each of said apertures to engage said peripheral shoulder.
Claim 4
Dependent Claim
18 words
The cuvette matrix and tray of claim 2, wherein the apertures of said tray are quadrangular in shape.
Claim 5
Dependent Claim
24 words
The cuvette matrix and tray as in claim 3, wherein one or more interconnected wells can be removed from the matrix at a time.
Claim 6
Dependent Claim
29 words
The cuvette matrix and tray as in claim 4, wherein said connecting stems are breakable such that a well si removable by breaking the stem connected to said well.
Claim 7
Dependent Claim
34 words
The cuvette matrix and tray as in claim 5, wherein the breakable stems flexibly interconnecting one well to the other are connectingly disposed along the sides of the wells, or along alternate sides thereof.
Claim 8
Dependent Claim
39 words
The cuvette matrix and tray as in claim 3, wherein said severed inward wall of each of said apertures is configurated as a deformable flexible finger for frictionally holding the confined well against an opposite wall of said aperture.
Claim 9
Dependent Claim
19 words
The cuvette matrix and tray as in claim 7, wherein said flexible finger is adapted to be horizontally flexible.
Claim 10
Dependent Claim
21 words
The cuvette matrix and tray as in claim 8, wherein said aperture has only one finger for holding said well therein.
Claim 11
Dependent Claim
22 words
The cuvette matrix and tray as in claim 1, wherein the closed bottom of each of said well is optically light transmitting.
Claim 12
Dependent Claim
60 words
The cuvette matrix and tray as in claim 1, wherein said inward wall of each of said apertures in said tray is severed diagonally at substantially the center of said side wall to provide a diagonal gap in said inward wall and thereby form a pair of fingers which flex horizontally when a cuvette is frictionally forced into said aperture.
