Lubricants

Optimol tribometers: leading in lubricants research and development for more than 50 years

Our tribological solutions make it possible to save time and money in the development and quality assurance of lubricants and additives

Lubricants are used in an enormous variety of applications. Whether we are talking about drive chains or machining technologies, lubricants whose properties are perfectly suitable for the respective field of application can be found everywhere. And this is exactly where our tribological solutions come into play. Optimol Instruments offers a wide range of functional, application-oriented laboratory tests that help predict the lubricants' performance capability in the field. From classic standardised tests for quantifying friction, wear and scuffing resistance to dynamic testing cycles with special test specimens, we offer more than 30 standardised test scenarios for lubricants. As it is only the most promising product candidate that will finally be sent to the component test bench or subjected to field testing for approval, it is possible to save valuable time and costs when it comes to the pre-selection of product formulations and quality assurance.

However, this does not apply exclusively to pre-formulated lubricants, but also to their additives which either promote or suppress certain properties.
