Air displacement pipette or repetitive pipette? Make the right choice for your application
27 Apr 2023Selecting the correct liquid handling device based on the medium used, the delivery volume, and the frequency of delivery is essential for precise and reliable work. The device must also provide optimum support for the application and contribute to efficiency in the laboratory. BRANDTECH Scientific provides various air displacement pipettes and repetitive pipettes. In this application note, BRANDTECH Scientific shows the main differences between these groups and points out important selection criteria that make it easy to choose the right device.

Transferpettor™ Positive Displacement Pipette
BRANDTECH® Scientific, Inc.The Transferpettor™ is the ideal tool for use with liquids that render traditional air displacement pipettes ineffective. Unlike air displacement pipettes, the piston of the Transferpettor™ directly expels the media from the tip, wiping the tip walls completely clean. This results in negligible residual wetting and highly accurate, reproducible results, especially with viscous, foaming, high-vapor-pressure, and other "problematic" liquids.
