Available in nine sizes, the Combitips offer safe, accurate dispensing of liquids by positive displacement. Colour coded for easy size recognition they have elongated tips (sizes 2.5 mL, 5 mL, 10 mL) to completely empty all standard laboratory tubes and a dispenser box with chute. Designed for applications requiring precise pipetting of identical amounts of liquids in series, their hermetically sealed piston prevents contamination of the pipette and the positive-displacement principle supports high-precision dispensing of problematic liquids, such as those with high density/high salt, high vapor pressure or high viscosity. No slip agents are used in the manufacturing of this product, ensuring the best results in bioassays and other sensitive analytical methods.
