-Five operating modes that are simple to set and use simplify most pipetting applications -Large, clear LCD screen with clear operational symbols and words makes settings obvious -Optimized standard design of the tip cone on the single channel pipettes allows for the use of BRAND or other manufacturers' high quality tips -Innovative "O-rings" on tip cones of the multichannel pipettes reduce tip-mounting and ejection forces, and allows for the use of BRAND or other manufacturers' high quality tips -Easy Calibration™ system reduces need for off-site calibration and simplifies conformity with ISO/GLP guidelines -Patented "gel" mode for loading of electrophoresis gels (not available on 1000µL and 5mL instruments) -Shaft and manifold are easy to remove and are autoclavable for sterile applications (at 121°C/250°F) -On multichannel models, tip cones are individually removable and replaceable for ease of cleaning and repair in the lab - no need to send the instrument out for routine maintenance
