You understand the importance of precision in lab work, and positive displacement pipettes are essential for achieving that. Designed for accuracy when working with hard-to-measure liquids, positive displacement pipettes are critical for handling viscous or volatile liquids, ensuring your measurements are spot-on every time.

What is the difference between an air displacement and a positive displacement pipette?

Positive displacement pipettes are best when measuring and transferring accurate volumes of viscous, volatile, or dense liquids. Air displacement pipettes, in contrast, are better suited for standard aqueous solutions, using an air cushion to measure and transfer liquids, which is less effective for challenging sample mediums.

When working with positive displacement pipette and challenging liquids, be sure to use pipette tips that are intended for your sample type and pipette.
