A 4 mL amber standard high-recovery vial is commonly used in analytical laboratories for storing and analyzing small-volume samples while minimizing sample loss. The amber glass protects light-sensitive compounds from degradation, and the high-recovery (conical-bottom) design allows nearly complete retrieval of the sample
The vial's tapered or V-shaped bottom concentrates the sample so that an autosampler needle or pipette can recover almost all of the liquid, reducing dead volume and improving reproducibility. This is especially useful when:
