Ring and plate tensiometer DCAT 15

for surface and interfacial tension measurementfor surface free energyfor contact angle measurement

The tensiometers of the DCAT series are measuring instruments for force-based investigation of surface and interface properties. Because of the compact and modular product design of the DCAT series, a bespoke combination of device and accessories can be found for any use case. The DCAT 15 is the standard model of the DCAT series and offers more measurement methods and modular extensions compared to the entry-level models. In addition to measuring surface and interfacial tension as well as density, the DCAT 15 can be used to determine dynamic contact angles, the surface energy of solids and to investigate sedimentation and penetration properties. Together with the LDU 25 liquid dosing unit, automatic concentration series can be generated to determine the critical micelle formation concentration. Possible measurements: - surface and interfacial tension - liquid and solid density - dynamic contact angles - surface energy of solids - determination of the critical micelle concentration (CMC) - sedimentation/penetration Features: - electrodynamic compensation weighing system with a resolution of up to 100 μg and with automatic as well as manual calibration function - software-controlled, motorised height positioning of sample vessels at variable speed - automatic coupling lock for the weighing system - automatic collision protection for sample bodies during measurement - illuminated sample chamber - built-in magnetic stirrer - digital thermometer with ports for two Pt100 temperature sensors - upgradeable with the LDU 25 liquid dosing unit for the automated generation of concentration series to determine critical micelle concentration (CMC)
