Macro-volume pipettors (1–10 mL range) are used in clinical reference laboratories for bulk reagent preparation, volumetric dispensing of working solutions, and sample aliquoting at scales that exceed standard 200–1000 µL pipettors. The reservoir tip's wide bore accommodates the larger-diameter macro pipettor cone and reduces back-pressure during aspiration of higher-volume samples — critical for accurate delivery of viscous protein solutions, glycerol-based reagents, and serum aliquots at the 5000–10000 µL scale.
