Determining low and ultra-low interfacial tensions (IFT) of liquids is important in many applications, for example, enhanced oil recovery and the development of new surfactants. To determine low to ultra-low interfacial tension properties between liquids, DataPhysics Instruments offers their SVT Spinning-Drop-Tensiometer, which guarantees an efficient measuring procedure, the highest precision and reproducible results. This application note showcases the measurement procedure of SVT Spinning-Drop-Tensiometers.
Yogurt has become one of the most popular dairy products in recent years. Yogurt is made by the gelation of milk using bacteria. The temperature plays an important role in the gelation process, as it significantly affects the gelation point and therefore the quality of the yogurt when it comes to, for example, mouth feel. This process is usually studied by measuring pH-values. However, these values can only offer
little information in the real gel formation process. The MultiScan (MS 20) from DataPhysics Instruments is a compact and versatile&#
The wetting properties of powders have attracted increasing attention, because they are essential parameters in various application fields, like ceramics, clays, pharmaceutical products, and cosmetics. Ferrosilicon powder, for example, is used to produce steel
as well as silicon for solar panels and computer chips. The Washburn method is one of the most commonly used methods to analyse the wetting behaviour of powders with a liquid. However, this method is limited to hydrophilic samples. Using the optical contact angle meter from DataPhysics Instruments, the wetting behavio
