Contact angle measuring device DCAT 25SF

for surface tension measurementfor cablesfor yarn

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 25SF single-fibre tensiometer contains a high-precision weighing system with a resolution of up to 0.1 μg. This enables measurements even on single carbon or glass fibres. Possible measurements: - surface and interfacial tension - liquid density - dynamic contact angles on e.g., single carbon or glass fibres - surface energy of solids - determination of critical micelle concentration (CMC) - surface pressure - viscoelasticity of monolayers Features: - electrodynamic weighing system with the highest resolution of up to 0.1 μg - 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 - closed, illuminated sample chamber for measurement at defined humidity and temperature - built-in magnetic stirrer - digital thermometer with ports for two Pt100 temperature sensors - upgradeable with various temperature control systems for measurements at temperatures between -15 °C and 135 °C - upgradeable with the LDU 25 liquid dosing unit for the automated generation of concentration series to determine critical micelle concentration (CMC) - upgradeable with Langmuir trough module LTMr for the investigation of monolayers
