A sample carrier comprising a top wall, a base, and a support wall joining the top wall and the base. The top wall includes aligned, spaced-apart openings on at least one side of the support wall which are sized to receive sample tubes. Sleeves depending from the top wall and circumscribing each opening direct sample tubes into sample tube holding areas. The sample tube holding areas each include one or more retaining walls extending upward from the base opposite the support wall. Springs extending outward from the support wall bias sample tubes against the retaining walls. A drip shield comprising a cover plate, a pair of through-holes for accessing sample tubes in the sample carrier, and a depending fin which separates sample tubes on opposite sides of the support wall protects against cross-contamination between sample tubes held by the sample carrier.

We claim: 1. A sample carrier for use in holding and centering a plurality of sample tubes for access by a robotic pipetting device, the sample carrier comprising: a top wall having a plurality of spaced-apart openings, each opening being dimensioned to receive one of a plurality of sample tubes therethrough; a plurality of sleeves, each sleeve depending from a bottom surface of the top wall and circumscribing one of the openings, each sleeve having an inner surface dimensioned to receive a vessel component of one of the sample tubes therethrough, and each sleeve having an opening configured and arranged to permit viewing of a label affixed to one of the sample tubes; a base defining a plurality of sample tube holding areas, each sample tube holding area corresponding to one of the openings and having one or more upwardly extending retaining walls opposite the support wall for holding one of the sample tubes in a substantially fixed, vertical orientation below the corresponding opening; a support wall joining the top wall and the base; and a plurality of springs extending outward from the support wall, each spring being associated with one of the sample tube holding areas, wherein the springs are configured and arranged so that each spring biases one of the sample tubes against the one or more retaining walls of the associated sample tube holding area. 2. The sample carrier of claim 1, wherein the top wail includes a series of the openings aligned along both sides of the support wall. 3. The sample cater of claim 1, wherein the openings are of the same or different sizes. 4. The sample carrier of claim 1 further comprising one or more of the sample tubes, each sample tube being present in one of the sample tube holding areas, wherein a cap component of at least one of the sample tubes is in touching contact with the inner surface of the corresponding sleeve. 5. The sample carrier of claim 1, wherein the openings are generally circular and the sleeves are generally cylindrical. 6. The sample carrier of claim 1, wherein the top wall has upwardly flared edges to facilitate handling of the sample carrier. 7. The sample carrier of claim 6, wherein the flared edges of the top wall include a plurality of recesses, each recess being adjacent one of the openings to provide finger access to sample tubes held by the sample carrier. 8. The sample carrier of claim 1 further comprising end walls joined to the base and a plurality of partitions, each partition extending radially or perpendicularly outward front the support wall and separating adjacent sample tube holding areas. 9. The sample carrier of claim 8, wherein each partition and a pair of retaining walls are joined to form a Y-shaped divider. 10. The sample carrier of claim 1, wherein each spring is a leaf spring. 11. The sample carrier of claim 10, wherein the springs are positioned between upper and lower portions of the support wall. 12. The sample carrier of claim 4, wherein the longitudinal axis of the cap component is within about 0.125 inches of the longitudinal axis of the corresponding opening. 13. The sample carrier of claim 4, wherein the longitudinal axis of the cap component is within about 0.1 inches of the longitudinal axis of the corresponding opening. 14. The sample carrier of claim 1, wherein the sample carrier has an arcuate shape. 15. A sample carrier for use in holding and centering a plurality of sample tubes for access by a robotic pipetting device, the sample carrier comprising: a top wall having two sets of aligned, annular, spaced-apart openings, each opening being dimensioned to receive a sample tube therethrough; a plurality of cylindrical sleeves, each sleeve depending from a bottom surface of the top wall and circumscribing one of the openings, each sleeve having an inner surface dimensioned to receive a vessel component of one of the sample tubes therethrough, and each sleeve having an opening configured and arranged to permit viewing of a label affixed to one of the sample tubes; a base defining a plurality of sample tube holding areas, each sample tube holding area corresponding to one of the openings and having one or more upwardly extending retaining walls opposite the support wall for holding one of the sample tubes in a substantially fixed, vertical orientation below the corresponding opening; a support wall joining the top wall and the base, wherein the sets of openings are positioned on opposite sides of the support wall; and a plurality of leaf springs, each leaf spring having a pair of spring arms extending outward from opposite sides of the support wall, each spring arm being associated with one of the sample tube holding areas, wherein the leaf springs are configured and arranged so that each spring arm biases one of the sample tubes against the one or more retaining walls of the associated sample tube holding area. 16. The sample carrier of claim 15, wherein the top wall has upwardly flared edges to facilitate handling of the sample carrier. 17. The sample carrier of claim 16, wherein the flared edges of the top wall include a plurality of recesses, each recess being adjacent one of the openings to provide finger access to sample tubes held by the sample carrier. 18. The sample carrier of claim 15 further comprising lateral end walls joined to the base and a plurality of partitions, each partition extending radially or longitudinally outward from the support wall and separating adjacent sample tube holding areas. 19. The sample carrier of claim 18, wherein each partition and a pair of retaining walls are joined to form a Y-shaped divider. 20. The sample carrier of claim 15 further comprising one or more of the sample tubes, each sample tube being present in one of the sample tube holding areas, wherein a cap component of at least one of the sample tubes is in touching contact with the inner surface of the corresponding sleeve. 21. The sample carrier of claim 20, wherein the longitudinal axis of the cap component is within 0.125 inches of the longitudinal axis of the corresponding opening. 22. The sample carrier of claim 20, wherein the longitudinal axis of the cap component is within about 0.1 inches of the longitudinal axis of the corresponding opening. 23. The sample carrier of claim 15, wherein each leaf spring is positioned between upper and lower portions of the support wall. 24. The sample carrier of claim 15 wherein the sample carrier has an arcuate shape.
