Lubricants Testing

Standard and customized tests to accurately characterize wear on a part and the efficiency of lubricants

Evaluating Lubricity and Tribological Properties of Lubricants and Additives

Lubricants and additives play a significant role in many industries. Their performance is critical to the speed, reliability, and life of nearly every type of machinery. To design lubricant formulations that deliver the best results, lubricity and tribology tests must replicate extreme pressures and real-world conditions.

Using the right lubricant formula can reduce the friction and wear between surfaces. Many industries have defined standards and test methods to characterize lubricity quality. For example, brakes, clutches, and engines are all tested for properties in accordance with ASTM, DIN, JIS, ISO and other standards.

Why invest in an in-house solution?

Many manufacturers rely on expensive, and time-intensive contract testing services to evaluate and research new lubricants. As an alternative, Bruker's UMT TriboLab benchtop tester performs multiple tests for perfecting chemistry and proving the performance of formulations. A wide range of drives and sensors enables engineers to perform both standard and customized tests. Our solution provides a fast, affordable path to perfecting chemistry and proving out formulations​.

  • Test samples on a small scale and correlate to large, expensive test rigs 
  • Innovate faster with in-process evaluations of formulas 
  • Easily change testing conditions as you develop formations 
  • Perform Quality Assurance, Quality Control, and R&D in one lab on one tool
