BrandTech Transferpettor

This accurate digital pipettor operates with positive-displacement. Easy to read due to digital volume display. Transferpettor may even be used with the most corrosive reagents because of polypropylene tips and polyethylene plunger seals. Accuracy is ±0.3%. Precision is 0.2%.

The Transferpettor® delivers high-precision pipetting of viscous, foaming, and high vapor pressure liquids—ideal when air-displacement pipettes reach their limits. Based on the positive displacement principle, the piston is in direct contact with the aspirated liquid and fits tightly to wipe the tip walls clean, virtually to the last drop. This ensures reproducible results and negligible residual wetting, so tips don’t need to be discarded after each pipetting step. Areas of application Foaming media (e.g., surfactant solutions) High vapor pressure liquids (up to 500 mbar; e.g., alcohols, ether, hydrocarbons) Highly viscous media (up to 140,000 mm²/s, volume-dependent, see exclusion limits in manual) High-density media with up to 13.6 g/cm³ (macro, PP caps) or 3,8 g/cm³ (micro, glass capillaries) For Transferpettor® micro with glass capillaries, the Repair Set is recommended as additional equipment for maintenance to replace the piston rod and seal. Alternatively, the device can be sent to our technical service for repair. Limitations of use: Density up to 13.65 g/cm³ (macro, PP caps) or 3.8 g/cm³ (micro, glass capillaries) Vapor pressure up to 500 mbar Kinematic viscosity up to: Nominal volume 1/ 2/ 5 µl: 6.000 mm² /s; nominal volume 10 µl: 20.000 mm² /s; nominal volume 25 µl: 50.000 mm² /s; nominal volume 50 µl: 100.000 mm² /s; nominal volume 100 µl: 140.000 mm² /s (Operating temperature: 15 - 40 °C (59 °F - 104 °F))
