In the detergent industry, but also in the development of paints and coatings, measuring surface and interface tension as well as dynamic contact angles is very important. With the tensiometer DCAT 25 from DataPhysics Instruments and its standardised sample bodies you can conduct those and more measurements precisely and efficiently. The unique collision protection ensures that valuable sample bodies stay intact. The complimentary software allows to define your own measurement and cleaning cycles.
On top of standard measurements, the expandable, modular DCAT 25 offers a variety of additional possibilities. Available are, for example, temperature chambers up to 300 °C and a Langmuir through for studying monolayers. For wetting analyses, an optional camera module allows to correlate image-based and weight-based measurements, which enables the calculation of adhesive force per unit area. When analysing surfactants, the dosing system with up to four syringes makes automatic measurements of the critical micelle concentration (CMC) exceptionally efficient.
