Transferpettor, Positive Displacement Pipettes

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.

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

Operating Limits and Exclusions

Liquids unsuitable for use with the Transferpettor™ 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
• Temperature of instrument and reagents must be between 15º and 40ºC
• Instrument, tips and seals are not autoclavable
