Reliable results and rapid processing

• You would like to optimize your product?
• You would like to know the interfacial properties of your product?
• You have samples, but no tensiometer or contact angle measuring instrument?
• Your laboratory is snowed under with work?
• You need to be sure that a KRÜSS instrument can help you?
• You are simply looking for a partner to discuss an application problem?

Then we are the ideal partner for you!

In addition to specialized measuring techniques, KRÜSS GmbH can also offer you an excellently equipped laboratory and a team of experts to advise you.

Our offer includes sample and application tests as well as contract analyses, e.g. if you only have a low sample throughput – or if you cannot make the measurements yourself for other reasons.

Our customers profit from our great experience in sample preparation and in defining application-specific measuring conditions.

Comprehensive: the measuring methods that we offer

Surface and interface characterization using tensiometric methods:

• Static surface and interfacial tension by the Wilhelmy plate method and Du Nouy ring method
• Determination of the critical micelle formation concentration (CMC) and the critical aggregation constant (CAC)
• Dynamic surface tension measurements with the bubble pressure method
• Dynamic interfacial tension measurements by the drop volume method
• Contact angle measurements on plane surfaces by the Wilhelmy plate method and contact angle measurements on powder and fiber samples according to the Washburn sorption method
• Single fiber measurements to determine the wetting behavior
• Surface free energy determinations on powders, fibers, textiles and plane solids based on contact angle measurements

Surface and interface characterization using optical methods:

• Contact angle measurements on non-porous and porous solids as static or dynamic measurements, or as a function of time (e.g. for adsorption processes)
• Determination of the surface free energy of non-porous and porous solids based on contact angle measurements
• Determination of the polar and disperse fractions of the surface free energy
• Determination of adhesion energies

Professional: working in compliance with standards and directives

Our laboratory works according to the following EU, ISO, DIN and ASTM standards:

Reliable: our order processing

• Inform yourself about the favorably-priced possibilities for contact analyses. Measurements on single samples are planned and carried out in just the same way as large measuring series. We are also able to meet your deadlines to a very large extent – after agreement we can carry out measurements at very short notice (24h service)
• If you are considering purchasing an instrument then please contact us if you want to test its suitability for solving your problem

A non-binding request for information about contract analyses can be sent to us via Email, phone or your local KRÜSS partner.

For requests from the USA, Mexico or Canada, you are free to contact our contract laboratory in the USA:
