Contact angle measuring instrument OCA 25 HTV

high-precisionfor high-temperature applications

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The special model OCA 25-HTV1800 is based on the OCA 25 standard model. It is suitable for measuring contact angles at high temperatures of up to 1800 °C and in a vacuum of up to 0.00001 mbar or in an inert gas atmosphere. With an optional dosing system, the OCA 25-HTV1800 can also be used at room temperature for all standard analyses such as the determination of surface energy and the measurement of interfacial tensions. Features of the OCA 25 HTV1800 special model: - high-temperature furnace for measurements in temperatures of up to 1800 °C - vacuum-tight flange with connections for an optional turbomolecular pump - gas supply system for argon and nitrogen - high-performance power supply and control electronics - optional dosing system for measurements at room temperature - optional transport trolley for easy transport of the entire system - optional turbomolecular pump for pressures of up to 0.00001 mbar
