The Brabender AbsorptoMeter is the leading solution for liquid absorption testing and precise OAN determination of carbon black, silica, and pigments in full compliance with ASTM and ISO standards. Its automated, software-driven system replaces manual methods, reducing errors and maximizing repeatability. Its uniquely high torque performance of up to 25 Nm and two dedicated mixer designs provide unmatched versatility and stable results, even with challenging materials. With MetaBridge fully integrated, the system offers intuitive workflow control, live monitoring of absorption curves, secure data handling, and simplified reporting, plus straightforward integration into LIMS and ERP systems for consistent data management.

Key features

Liquid absorption testing with confidence

Ensure global quality standards are met – without complexity. The Brabender AbsorptoMeter is built for precise liquid absorption testing, including oil absorption number (OAN) testing in carbon black, silica, pigments, and fillers. Complying with internationally recognized ASTM and ISO oil absorption standards, including defined torque limit switch (TSL) and integrated normalization for inter-chamber comparability, it enables fully traceable, repeatable results. Whether you’re validating batch quality or aligning with regulatory demands, the Brabender AbsorptoMeter gives you confidence in every test – accurate, accepted, and audit-ready.

Embrace precision and automation

Conventional OAN and other liquid absorption testing methods involve inconsistent techniques, manual dosing, and subjective endpoints – all of which impact accuracy and reproducibility. These limitations slow processes and reduce data confidence. The Brabender AbsorptoMeter addresses these issues through precise, automated control overdosing and evaluation. Programmable speed range from 5 min⁻¹ to 200 min⁻¹ ensures defined shear conditions. This eliminates human error, improves reliability, and ensures efficient, standardized liquid absorption testing – ready for the demands of today’s lab environments.

MetaBridge software for premium results

With industry-leading MetaBridge software, the Brabender AbsorptoMeter defines the benchmark for reliable liquid absorption analysis. By integrating weighing, dosing, and temperature control, it ensures stable, reproducible conditions and eliminates variability. Automated startup and cleaning routines maximize uptime and consistency. A broad library of standard and customizable methods supports diverse applications, including complex multi-liquid dosing. Measurements can be monitored live across the network, while real-time reference and correlation tools detect deviations instantly. Standardized exports, built-in mailing, and seamless LIMS/ERP integration ensure effortless data flow without manual transfer.

Discover versatile titration options

Quality slips when a single pump tries to serve every viscosity; shear and feed become unpredictable. The Brabender AbsorptoMeter stabilizes processing by adapting dosing rate to fluid response in real time. Expand flexibility with up to four USB-connected burettes, running in sequence or simultaneously. Application-optimized tubing and programmable dosing rates from 0.025 ml/100 g to 100 ml/100 g sustain accurate delivery up to 150,000 mPa·s. Outcome: reliable wetting and dispersion, uniform mixing, and reproducible absorption values for specification checks and formula optimization.

Durable design

Laboratory conditions are often harsh when working with powdery materials. The Brabender AbsorptoMeter's stainless steel casing is engineered for resistance against mechanical and chemical stress. This robust build protects against fine-particle intrusion, ensuring smooth, uninterrupted operation and a longer device lifespan.
