Positive displacement pipettes:
Make: BRAND
Model: Transferpettor Digital
The Transferpettor is ideal for liquids when air displacement pipettes just won't work. Viscous, foaming, high vapor pressure: the Transferpettor can handle them all, with the precision and accuracy you expect from a BRAND pipette. This is the pipette for your most demanding pipetting operations.
The Transferpettor operates on the positive displacement principle. In contrast with air displacement pipettes, the piston is in direct contact with the aspirated liquid. The tightly fitting piston always wipes the walls of the tips completely clean - literally to the last drop. Therefore providing reproducible results. There is no need to discard tips after each pipetting operation, since residual wetting is negligible.
Limitations of use:
Density up to 3.8 g/cm³
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))

Key Features
Core design and principle:
Uses the positive displacement principle, where the piston is in direct contact with the liquid rather than separated by an air cushion.The tight-fitting piston wipes the capillary walls nearly dry, allowing dispensing “to the last drop” with very low residual wetting and good reproducibility.
Liquids it can handle:
Suitable for viscous media (e.g., concentrated protein solutions, oils, resins, fats) up to very high kinematic viscosities (tens of thousands of mm²/s depending on volume).Can accurately dispense high‑density liquids (e.g., glycerol, mercury, sulfuric acid) and high vapor pressure solvents (alcohols, ethers, hydrocarbons) without recalibration within specified limits.
Performance and volume range:
Available in multiple digital adjustable-volume models covering roughly 2.5 µL to 10 mL, with typical accuracy around 0.5–3% and CV around 0.2–0.8% depending on size.Designed to maintain precision even with liquids that cause serious errors in standard air‑displacement pipettes.
Tip and reusability features:
Uses special capillaries/caps (glass or PP, depending on volume) with a piston that can often be reused because residual wetting is minimal, reducing consumable use and sample waste.For applications where absolutely no carry‑over is tolerable (e.g., infectious or radioactive samples), manufacturers recommend switching to disposable‑tip air‑displacement models instead.
Typical applications:
Handling concentrated protein and enzyme solutions, detergents/surfactants such as Tween solutions, oils and greases, resins, and problematic organic solvents.Useful whenever standard air‑displacement pipettes show dripping, foaming, inaccurate volumes, or poor repeatability due to the liquid’s properties
