New exclusive representative in South Africa.
In order to succeed in new markets we have an exclusive distributor since July 2003 in South Africa, company ADI Scientific (Pty) Ltd., Advanced Laboratory Solutions.
15.09.03 Use of the new Spinning Drop Tensiometer SITE100 for characterization of critical micelle concentrations.
The stability of emulsions is to a large extent determined by interfacial properties of the participating phases, and their storage stability can be optimized by the use of emulsifiers to lower the interfacial tension. This is made possible by the fact that the reduction in the interfacial tension lowers the driving force for separating the oil and water phases. The optimum adjustment of the necessary amount at a particular temperature depends on the diffusion rate at the interfacial boundary and the critical micelle concentration, among other things.

The Washburn "C" Factor for characterization of porous coatings.
Porous coatings find application in a wide variety of industrial, military, and medical applications. For example, porous photo and electro catalytic coatings are used in applications ranging from chromate production to cyanide destruction - and are also being explored for use in air and water treatment. In the medical field, porous coatings are used on the surface of replacement joints to promote a stable bone-implant interface by providing support for both ingrowth and ongrowth. Porous coatings are also widely used to support various reagents for blood and plasma analysis on diagnostic strips and slides.
10.09.03 DSA100/DSA100L - The new contact angle measuring system generation. Flexible sample size, flexible measuring technique – with its double modularity concept KRUSS GmbH has revolutionized contact angle measuring technology.

DSA10HT - The high temperature measuring system for contact angle measurements on glasses, metals and alloys at temperature up to 1900°C.
05.09.03 Introduction to online business
In the last few days it has become possible to purchase directly from KRUSS via the Internet. Initially you will find here the new PocketDyne Bubble Pressure tensiometer BP2100.

KRUSS homepage with a new appearance
In the last few days the German pages of the KRUSS homepage have appeared in a new design.

KRUSS GmbH honoured for innovative energy.
KRUSS GmbH has been honoured for its outstanding performances in the fields of innovation and creativity by being included as one of the TOP100 medium-sized companies in Germany.
01.09.03 Again we are happy to present numerous new products from KRUSS. Let us highlight two products here: The DSA100 represents the new generation of contact angle measuring systems that comes with revolutionary new features. The DSA10HT on the other hand allows you to measure contact angles on glasses, metals and alloys at temperatures up to 1900°C.

Also we have changed a lot in the way we present ourselves towards you and all our customers. We are proud to present our Online Shop and our new Web-Design. The Online Shop allows you to try out our new bubble pressure tensiometer PocketDyne in a virtual manner with plenty of information at your finger tips and gives you access to an easy and secured way for ordering the instrument.

We also underline just another time our claim to be the solution provider with our reports on new applications taken from industries that use our instrumentation. One of the things we show are first results from our new video supported Spinning Drop Tensiometer SITE100 for the measurement of very small interfacial tensions.

And we are especially happy to announce that KRUSS has been awarded as one of the TOP100 innovative medium-sized companies in Germany in 2003. We have officially received the award at a gala night on July 4 in Berlin which was hosted by Prof. Dr. h.c. Lothar Spath, former prime minister of Baden-Wurttemberg. We were awarded for outstanding achievements in innovation and creativity.
01.02.03 Increased activities in application support

- Surface Science Contract Lab in U.S. to Better Serve the Needs of Growing Customer Base

- Surface science specialist adds to the strength of our rapidly expanding application laboratory in Hamburg, Germany

In order to better serve KRUSS customers' contract laboratory needs, KRUSS has a strategic alliance with company Augustine Scientific, Ohio, Dr. Christopher Rulison. Augustine Scientific exclusively uses KRUSS instrumentation for all surface tension and contact angle measurements. Dr. Rulison will operate in close partnership with KRUSS’ International facilities to provide the best data analysis for our customers as a precursor to, or in lieu of, instrumentation purchases.

To support the advancement of the field of surface science, Christine Bilke-Krause joined KRUSS in June 2002 as the head of our Hamburg, Germany application development laboratory. Mrs. Bilke-Krause brought to KRUSS more than a decade of surface science expertise gained while studying at Humboldt University of Berlin and the University of Leipzig as well as several years of corporate surface science experience.

In addition KRUSS continues to operate sales demonstration and application development laboratories in Charlotte, NC, and Palaiseau, France.
01.02.03 Adhesion Energy and Interfacial Tension – Two Related Coating/Substrate Interfacial Properties. Which is More Important for Your Application, and Why ?
The major reason for determining surface energies and surface polarities for coatings (including adhesives and inks) and substrates is as a basis for modification of either one or the other (or possibly both) to improve either wetting, spreading, or adhesion. Two important interfacial parameters are typically gained from such work: the physiochemical adhesion energy between the coating and the substrate, and the interfacial tension that remains, once the substrate/coating interface is formed. The former property (adhesion energy) has much to do with how favorable the formation of such a substrate/coating "bond" is. The later property (interfacial tension) has to do with how difficult such a bond will be to break, once it is formed.
01.02.03 Assessing the cleaning ability of aqueous surfactant solutions on soiled hydrophobic textile fabrics by using contact angle and surface tension measurements
This article presents a practical way of making an estimation based on surface tension measurements between dirt components and the cleaning solution as well as on contact angle measurements made on hydrophobic textiles; this makes it possible to predict the cleaning effect.
01.02.03 Contact Angle Measurements in Deepenings
Contact angle measurements in holes, bowls and wells were up to now not possible due to their specific geometry. With the new TDA10A, now the wetting properties of these samples can be characterised precisely. By using a new arrangement of the measurement system and the piezo dosing system these new applications were made possible.

Contact angle measurements in the wells of micro-titer plates can be performed as well as measurements on the concave side of contact lenses or on small areas of micro-mechanical devices.
