Pipette Controllers

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))

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

The key features of the Brand Titrette bottle-top burette include precise titration within Class A error limits, a compact and robust design, and ease of use with separate control buttons for on/off, pause, and clearing the display. It has a digital display for easy volume reading, smooth and fast filling with non-slip hand wheels and precision gearing for drop-wise dispensing, and the titrating tube can be adjusted horizontally and vertically for flexible positioning. The burette operates without needing a power connection, is lightweight, disassembles quickly for cleaning or maintenance, and supports an optional PC interface for data transfer. It also comes with a telescoping filling tube, various bottle adapters, and light shield inspection windows for use with light-sensitive reagents.​

Precision and Ease of Use:

Meets Class A glass burette error limits for accuracy. Fingertip sensitivity with drop-wise titration. No need to switch between filling and titration modes; the device automatically detects the action. Large textured hand wheels and a smooth-running precision gear ensure easy and reliable operation.

Design and Flexibility:

Compact, lightweight, and robust design suitable for limited spaces without power connection. Adjustable titration tube position (horizontal and vertical) to accommodate different bottle sizes or magnetic stirrers. Telescoping filling tube allows use with different bottle heights.

Additional Functional Features:

Separate buttons for on/off, pause, and clear functions. Optional PC interface for direct data transfer. Easy calibration technology allows quick adjustments without tools. Supplied with performance certificate, battery-powered, and equipped with light protection windows for sensitive media.
