The lightweight pipettor is designed for fast and accurate one-handed operation. A fast release trigger dispenses the entire pipette contents. An optimally located thumb wheel rotates easily for precision aspirating or dispensing, down to a volume of one drop at a time – all while using a more relaxed grip. The thumb wheel also can be used to "blow out" the pipette. Available in three different pipette volumes, 2, 10 and 25mL, each color coded for easy identification. A self-stabilizing collar inside the silicone chuck holds either glass or plastic pipettes. Pipettors are resistant to acids, alkalies and most solvents and can be disassembled for cleaning. Overall length 171mm (6.75").
