Concentric Tube Microplate Autosample Interface In accordance with an illustrative embodiment of the invention, a system for obtaining a fluidic sample (114) from a container (110) is presented. The container defines a volume for holding the sample, the volume being closed by a seal (116). An outer tube (103) has a proximal end (107) and a distal end, the proximal end shaped to permit piercing the seal. An inner tube (105) has an end region (109) axially movable within the outer tube between a piercing position, wherein an end of the inner tube in the end region is retracted from the proximal end of the outer tube, and a transmission position, wherein the end of the inner tube extends axially beyond the proximal end of the outer tube. The outer tube and the inner tube form a tube assembly (101). At least one o f the tube assembly and the container can be moved to cause the outer tube to pierce the seal and, after the seal is pierced, the inner tube can be used i n the transmission position to permit fluid transfer with respect to the volum e.
