The Vision family of handheld, single- and multi-channel electronic pipettors features a touch wheel controller for intuitive and fast menu navigation. Features include a large, customizable, multi-color display; a 12-channel, 1250-μL pipettor; Bluetooth wireless PC connectivity; live, multi-language help menus; and a rechargeable lithium-ion battery. An ergonomic design and balanced weight provide comfortable and productive pipetting. The Tri-Lobe tip attachment mechanism maximizes tip stability and minimizes attachment and ejection force, creating a consistent and reliable tip-to-pipettor seal. Five single-channel models support volumes ranging from 0.5 μL to 5.0 mL. Four different 8- and 12-channel models support maximum volumes of 12.5, 125, 300 and 1250 μL, and two 16-channel models are available in volumes of 12.5 or 125 μL.
