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-PMC is based on the OCA 25 standard model. With its high-pressure measuring chamber, the special model OCA 25-PMC offers the possibility of carrying out measurements of interfacial tensions and contact angles under high-pressure of up to 750 bar and at temperatures between -30 °C and 200 °C.
This makes the OCA 25-PMC the ideal solution to investigate, for example, the interfacial tension between a surfactant solution and crude oil in reservoir conditions. It is also possible to determine the contact angle, for example, between rock, oil, and surfactant solution.
Features of the OCA 25 PMC special model:
- high-pressure chamber with optical sapphire glass
- pressure unit generating and controlling ambient and droplet pressure
- temperature controller for the measurement chamber
- removable magnetic positioning system for solid samples
