Abstract: A sample tube rack (10) for receiving at least one sample tube is provided, comprising: a bottom surface (12) comprising at least one opening (14) for receiving the sample tube, and at least two guiding elements (16, 16?, 16a-d) arranged on the bottom surface (12) adjacent to the opening (14), wherein each guiding element (16, 16?, 16a-d) extends substantially parallel to a vertical axis (18) of the opening (14) from the bottom surface (12) towards a top side (20) of the sample tube rack (10). The guiding elements (16, 16?, 16a-d) are arranged at different positions (17a-d) around the opening (14), such that a tube compartment (24) for receiving the sample tube is formed by the guiding elements (16, 16?, 16a-d) and the opening (14), wherein the guiding elements (16, 16?, 16a-d) are spaced apart from each other along a perimeter (21) of the opening (14), thereby forming at least two clearances (22) between the guiding elements (16, 16?, 16a-d) along the perimeter (21) of the opening (14).

Abstract: A slider assembly (10) for a transportation system (100) for transporting an object (101) is provided. The slider assembly (10) comprises a first support (12a) and a second support (12b), a first guiding element (14a) arranged on the first support (12a) and a second guiding element (14b) arranged on the second support (12b), wherein the first guiding element (14a) is configured to receive a first rail (104a) and the second guiding element (14b) is configured to receive a second rail (104b), such that the slider assembly (10) is slidably arrangeable on the first rail (104a) and the second rail (104b). The slider assembly further comprises a tolerance compensation element (18), which connects the first support (12a) and the second support (12b), such that at least a part of the first support (12a) and at least a part of the second support (12b) are spaced apart from each other, thereby allowing a relative movement of the first support (12a) and the second support (12b) with respect to each other.

The guiding elements (16. 16?, 16a-d) are arranged at different positions (17a-d) around the opening (14), such that a tube compartment (24) for receiving the sample tube is formed by the guiding elements (16, 16?, 16a-d) and the opening (14), wherein the guiding elements (16, 16?, 16a-d) are spaced apart from each other along a perimeter (21) of the opening (14), thereby forming at least two clearances (22) between the guiding elements (16, 16?, 16a-d) along the perimeter (21) of the opening (14).

Abstract: A sample tube rack for receiving at least one sample tube comprises an upper part comprising an upper surface, wherein at least one upper opening for receiving the sample tube is provided in the upper surface; an intermediate part comprising an intermediate surface, wherein at least one intermediate opening for receiving the sample tube is provided in the intermediate surface; and a lower part comprising a supporting surface, wherein at least one supporting position for supporting the sample tube is provided in the supporting surface. Therein, the intermediate part is connected to both the upper part and the lower part such that the at least one upper opening is substantially aligned above the at least one intermediate opening and above the at least one supporting position for receiving the at least one sample tube. At least one gripping orifice is provided in a lateral side of the lower part.
