27 Apr 2023

Selecting 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.

Transferpette® S

BRANDTECH® Scientific, Inc.

BRAND Transferpette® S pipettes offer superior performance, comfort, and value. Constructed with innovative composite materials, the Transferpette® S pipettes are lightweight and fully autoclavable.  The 4-digit display is easy to read for precise volume settings, and is always visible during pipetting. Adjustable and fixed-volume single channel pipettes from 0.1µL to 10mL, multichannels from 0.5µL to 100µL. Features: Thumb-tip volume selection allows you to set and secure the volume without shifting your hand position. Light weight and the shortest pipetting stroke among premium pipettes reduce the risk of repetitive strain injury. Accepts tips from most manufacturers.

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.
