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 volume and viscosity. Choose from the compact pistol or linear designs that dispense liquids with squeezable bulbs, buttons, or rotating thumb wheel. With rechargeable battery operation, the pipette controllers are cordless for maximum operation flexibility. Fitted filter sizes and colors vary among models.
