A simple, low cost, efficient and stable micro-vial configuration for handling micro-volume of sample fluids. The interior wall geometry of the inventive vial is designed to include several axial sections of various interior diameters to provide a range of functionalities to address various design considerations. The interior wall defined in the vial has a cylindrical sample section, a wider cylindrical alignment section, a tapered or conical guide section, and a relatively large cylindrical body section, arranged in sequence in that order along the center axis of the vial. The sample section is designed to hold a small volume of a sample fluid, and to receive the tip end of a capillary tube. The alignment section has a larger diameter than the sample section, designed to receive a cylindrical support that coaxially supports the relatively fragile capillary tube. The tip of the capillary tube dips into the micro-volume of sample fluid held in the sample section. The conical section functions to guide the capillary tube and the support tube into the alignment section and the tip of the capillary tube into the sample section. The body section has the largest diameter, for holding additional fluid if desired. |
