Pipette controllers rapidly fill and release accurate volumes from a wide range of glass or plastic blow-out pipettes. The ambidextrous devices offer different function modes and changeable speeds to adjust to different liquid volumes and viscosity. Choose from the compact pistol or linear designs that dispense liquids with squeezable bulbs, buttons, or a rotating thumbwheel. With rechargeable battery operation, the pipette controllers are cordless for maximum operational flexibility. Fitted filter sizes and colors vary among models.
