The Transferpettorâ„¢ is the ideal tool for use with liquids that render traditional air displacement pipettes ineffective. Unlike air displacement pipettes, the piston of the Transferpettorâ„¢ 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.
Product Features
- Designed for use with high-vapor-pressure liquids including alcohols, acetone and hydrocarbons
- Dispenses surfactants such as Tween® and Mucasol®
- Dispenses viscous and high density media such as concentrated protein solutions, oils, fats, resins, and glycerin

Liquids unsuitable for use with the Transferpettorâ„¢ include, but are not limited to those with:
- Density exceeding 13.6 g/cm3
- Viscosity exceeding 40,000 cSt (mm2/s), depending on instrument capacity
- Vapor pressure exceeding 500 mbar (50 kPa, 7.25 psi)
- Chemicals that attack either PP or PE
