Designed for fast and accurate 1-hand operation. The optimally located thumbwheel on this pipettor allows the operator to easily aspirate or dispense as little as a drop at a time, or to blow out the pipet—yet maintain a relaxed grip. A fast-release trigger dispenses the pipet's entire contents. Pipettor is resistant to acids, alkalis, and most solvents, and can be disassembled for cleaning. A self-stabilizing collar inside the silicone chuck holds glass or plastic pipets. Pipet volume is 2 mL (color-coded blue). Overall length, 6-3/4".
