Force Tensiometer – K100 now with new ADVANCE software

Our universal ADVANCE software platform will support our Force Tensiometer – K100 from now on. ADVANCE displays the logical workflow of scientific measurements on an intuitive user interface. The broad scope of methods offered by the K100 include, in addition to standard methods for surface and interfacial tension of liquids, completely automated CMC measurement and processes for characterization of the wettability of solids. ADVANCE controls measurement sequences with the aid of ready-made and easily adaptable automation programs, reducing manual steps to the absolute minimum.

New website for our Mobile Surface Analyzer – MSA

With our Mobile Surface Analyzer – MSA and its One-Click SFE measurement within a second, we have prepared the way for quality control of surfaces with the contact angle method. On a new website dedicated to the MSA you can see for yourself what advantages this instrument has when testing pre-treated, coated or cleaned surfaces.

Determining the wettability of carbon fiber tows from single fiber contact angle data
Determining the wettability of carbon fiber tows from single fiber contact angle data

Fibers are embedded in a plastic matrix during the manufacture of carbon fiber-reinforced plastics. A decisive factor is the good wettability of the fibers; poor wettability goes hand in hand with undesirable air inclusions and insufficient adhesion. It is therefore advantageous to know the fiber wettability in all processing stages during process design and quality monitoring: from individual fibers, via the bundled fibers, right up to the fabrics produced from those bundled fibers. Read about how the wettability of fiber tows can be predicted by measuring the contact angles of single fibers.

Breathing in a saline water world: the alkali flies of Mono Lake

Breathing in a saline water world: the alkali flies of Mono Lake

Trapping air bubbles and breathing underwater are well-known survival mechanisms of various small creatures, such as the water spider. They have hydrophobic leg hairs, called setae, which prevent water wetting and stabilize the boundary to air. The alkali flies have sought out the worst possible environment for living underwater. The water of their choice, found at Mono Lake (California, USA), has a high level of sodium carbonate which stabilizes hydrogen bonds. This greatly increases the rewetting pressure against air, which means that alkaline water should actually displace the air on the hairs. Two biologists at the California Institute of Technology, Pasadena, have now been able to determine the extremely hydrophobic structure of these setae on the alkali fly, which helps these insects to thrive in their environment.
