The tip of choice when working with Repeater®/Multipette® multi-dispenser pipettes from Eppendorf:
Thanks to their revolutionary design, Combitips® advanced dispenser tips provide many benefits for work in a modern laboratory. With an integrated piston, they function according to the positive displacement principle and ensure that the correct volume of liquid is dispensed regardless of the physical properties of the liquid (e.g., viscosity, volatility, density, temperature). Achieve high-precision dispensing, independent of the flow characteristics of the liquid, and safely work with radioactive or toxic materials due to the hermetically sealed piston that prevents aerosol contamination.

Eppendorf pioneered the Repeater®/Combitips® multi-dispenser system in 1978 and improved it several times since. It was the very first pipetting system allowing users to fill the tip once and dispense multiple times. The concept remains a driver for efficient liquid handling and a staple in many labs working with plates or series of tubes. In 2023, the Combitips® advanced pipette tip line-up has been certified with ACT® Environmental Impact Factor Labels by the My Green Lab® non-profit organization, making it the ideal choice for labs seeking more sustainable products.
