KRÜSS surface science equipment for research, development, educational, and quality control. Measuring contact angle, wetting, surface tension, interfacial tension, surface energy and surface viscosity for stability of emulsions and foams.  Both manual and automated systems. High throughput screening of single fiber samples. We specialize in powder and other porous materials.  KRÜSS supports a full line of tensiometers, contact angle measuring instruments  and foam analyzer and provide you with expert guidance. 

Take a look at us. In our portal we present the wide range of products and services that KRÜSS can provide. Our instruments are used for solving problems in the fields of surface and interface chemistry. For all our products comprehensive information and data sheets are available for downloading and printing out.

You will also find information about our technical services and application support in our laboratories throughout the world. Our colleagues provide results and offer competent advice. Literature references and substance data can be found in our comprehensive database. Information and downloads for your instruments can be called up with a mouse-click and are ready for immediate use. Even the visitors' section contains much interesting material.

We use our Newsletter to present new products, the latest scientific developments, new measuring methods, current information from our Service Department and our calendar of events so that you always have up-to-date information.

  • Response of liquid droplets to the field from a 0.4 T NdFeB magnet. [SURF1]=20 wt%, [MILS1]=20 wt%
  • Effect of magnetic field through dodecane on 20 wt% aqueous surfactant solutions. The magnet was smoothly moved up and down by hand. Left: inert SURF1; Right: magnetically active MILS1. To aid visualization the SURF1 solution was dyed with trace methyl orange.
