Which lab pipette should you use?
Selecting the right lab pipette or dispenser can be the key to success in your work. It can boost your efficiency and throughput and ensure reliable results for different pipetting use cases. Here is a quick introduction to the basics.
Air-Cushion Principle vs. Positive Displacement Principle
- Air-Cushion Principle: Air-cushion pipettes are most commonly used in labs around the world and ideal for liquids with physical properties similar to water. In this instrument type, the piston is separated from the liquid sample by a small air cushion. Temperature or humidity changes, as well as the physical properties of different liquids can affect the performance of air-cushion instruments. To reduce these risks however, Eppendorf air-cushion pipettes (Research plus , Reference 2 , Xplorer and epMotion) work with extra small air cushions and may be temporarily adjusted to different liquid types.
- Positive Displacement Principle: In positive displacement systems, the piston is part of the tip and in direct contact with the liquid. There is no air cushion that may be affected by liquid sample properties. These tools are therefore ideal for liquids with varying viscosity, volatility, surface tension or density as well as hot or cold liquids. The disposable tips with integrated pistons (e.g. Combitips advanced) also prevent contamination and help to keep user and instrument (Multipette, Varipette) safe when working with hazardous liquids.
