Available in nine sizes for use with any Repeater, Combitips advanced are designed for applications requiring pipetting of identical amounts of liquids in series. The hermetically sealed piston prevents contamination of the pipette, and the positive-displacement principle supports dispensing of problematic liquids, such as those with high density/high salt, high vapor pressure, or high viscosity. The elongated tips (size 2.5 mL, 5.0 mL, 10 mL) can help ensure complete emptying of all common vessels, while the funnel geometry promotes haptic feedback and prevents damage to gloves.
