The test tube holder includes an elongated tubular member which supports a pivot member thereby rendering the tubular member and pivot member relatively pivotable with respect to each other. Latch members provided on the tubular member and pivot member are engagable with complementary shaped latch members of other test tube holders to form a linkage. The pivotal relationship between the tubular member and the pivot member permit pivotal movement of one test tube holder with respect to the longitudinal axis of another test tube holder. A pivotal connection between the latch members of adjacent test tube holders also permits tilting of one test tube holder with respect to another test tube holder in the linkage. An adapter member for holding test tubes is insertable in the tubular member and pivot member assembly. The adapter member accommodates one size test tube and can be interchanged with another adapter member that accommodates another size test tube. Thus, the linkage of test tube holders can include test tubes of different size. The relative pivotal movement between test tube holders in the linkage permits stacking of the linkage in a fan-fold arrangement. The tilting movement between test tube holders in a linkage permits mixing of the contents of a test tube or a group of test tubes independent of all others in the linkage before a sample is tested. Under this arrangement, a linkage of test tubes of unlimited length can be provided.

A test tube holder comprising, (a) an elongated tubular member, elongated along a longitudinal axis, said tubular member having a first wall portion extending in the direction of said longitudinal axis and a first latch member formed on said first wall portion, (b) a pivot member supported on said elongated tubular member to permit relative pivotal movement between said pivot member and said tubular member about said longitudinal axis, said pivot member having a second wall portion extending in the direction of said longitudinal axis and a second latch member formed on said second wall portion such that said first and second latch members are relatively moveable toward and away from each other in a radial direction with reference to said longitudinal axis when there is said relative pivotal movement between said pivot member and said tubular member in opposite directions about said longitudinal axis, and said first and second latch members being respectively arranged on said first and second wall portions such that said first and second latch members are unengagable when said pivot member is supported on said elongated tubular member to permit relative pivotal movement between said pivot member and said tubular member about said longitudinal axis.
