Lightweight controllers weigh only 190g (6.6oz.) and have slim handgrip for comfort during serial pipetting, even for small hands. Pressure-sensitive buttons provide smooth control over pipetting speed. An additional control adjusts maximum speed for both accurate pipetting of small volumes and speedy movement of large volumes. Dual-mode switch provides either powered dispensing, gravity dispensing for volumetric work, or density gradient underlaying. Pipet adapter and 0.2µm filter are autoclavable for sterile use.
Easily replaceable NiMH battery provides eight full hours of continuous pipetting on a single four-hour charge. An LED charge indicator alerts user when two hours are left.
