Contact angle measuring device DCAT 25

for surface tension measurementcompactmodular

The tensiometers of the DCAT series are measuring instruments for force-based characterisation of surfaces and interfaces. 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 25 is the multifunctional all-round model of the series, which can be equipped with many additional modules and many software functions. Possible measurements: - surface and interfacial tension - liquid density and solid density - dynamic contact angles - surface energy of solids - automatic determination of the critical micelle concentration (CMC) - sedimentation and penetration - analysis of adhesive force - surface pressure - viscoelasticity of monolayers Features: - electrodynamic compensation weighing system with a resolution of up to 10 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 measurements at defined humidity and temperature - 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) - upgradeable with various temperature control systems for measurements at temperatures between -15 °C and 300 °C - upgradeable with the UpVideo DCAT camera to analyse the force of adhesion per area - upgradeable with Langmuir trough module LTMr for the investigation of monolayers
