Abstract
Abstract Apparatus for holding sample tubes comprises a casing divided into a plurality of compartments into which sample containing tubes are insertable and spring means are provided for holding the tubes within the compartments. The compartments are provided with openings in a front wall and there are coding elements insertable into the compartments which also have openings which are selectively registrable with the openings in the front wall of the compartments.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
Apparatus for holding sample tubes comprising a casing defining a plurality of compartments for the reception of sample tubes, means for holding tubes in said compartments, each compartment having a front wall, each said front wall having two openings formed therein said openings lying one above the other, and removable coding members insertable into said compartments, said coding members having in one face, two openings registrable with the two openings in said front walls of the compartments, in another face, an opening registrable with the lower opening in said front wall, in a further face, an opening registrable with the upper opening in said front wall and in a fourth face, no opening.
Claim 2
Dependent Claim
113 words
Apparatus for holding sample tubes comprising a casing defining a plurality of compartments for the reception of sample tubes, means for holding tubes in said compartments, each compartment having a front wall, each said front wall having two openings formed therein said openings lying one above the other, and removable coding members insertable into said compartments, said coding members having in one face, two openings registrable with the two openings in said front walls of the compartments, in another face, an opening registrable with the lower opening in said front wall, in a further face, an opening registrable with the upper opening in said front wall and in a fourth face, no opening.
Claim 3
Dependent Claim
47 words
Apparatus as claimed in claim 1 wherein a rear wall portion of a compaRtment is formed by two relatively inclined parts and biasing means is arranged adjacent a front portion of said compartment for urging a sample to its place into that compartment towards said rear wall.
Claim 4
Dependent Claim
15 words
Apparatus as claimed in claim 2 wherein said biasing means is constituted by a spring.
Claim 5
Dependent Claim
34 words
Apparatus as claimed in claim 2 wherein said biasing means is formed by a helical spring which extends across the front of said compartments and is spaced from said rear wall of said compartments.
Claim 6
Dependent Claim
32 words
Apparatus as claimed in claim 4 wherein each spring extends across the fronts of two compartments, an elongated hole for receiving the spring being formed in a wall separating said two compartments.
Claim 7
Dependent Claim
27 words
Apparatus as claimed in claim 5 wherein the ends of the spring are embedded in wall portions of the casing which are made of a synthetic resin.
Claim 8
Dependent Claim
65 words
Apparatus as claimed in claim 1, wherein said front walls of the compartments are opaque at least for a major part thereof, transparent, vertical strips are provided in the front walls of six adjacent compartments of the casing at the level of the junction between two adjacent compartments, and the coding members insertable therein are provided with digits which are visible through said transparent strips.
Claim 9
Dependent Claim
49 words
Apparatus as claimed in claim 7, wherein the front wall of one compartment of the plurality of compartments has a transparent portion between said two openings lying one above the other, the coding member arranged in said compartment having a digital marking which is visible through said transparent portion.
