Model 590

The ramé-hart Model 590 represents a most advanced and automated tool. This system includes our software-driven Automated Tilting Base assembly for measuring advancing, receding, and roll-off angles as well as contact angle hysteresis. The Automated Dispensing System, also controlled via DROPimage, is included for performing dynamic studies or adding precision and automation to the formation of pendant and sessile drops for analysis. Model 590 supports every available option including the Advanced Chamber, Environmental Chamber, and Environmental Fixture. Model 590 ships with DROPimage Advanced providing the capacity to design powerful experiments which may include drop volume and tilt control. DROPimage Advanced is also useful for measuring static and dynamic contact angle, surface energy, surface and interfacial tension.


Model 590 features our long optical bench with the fully modular advanced 3-axis stage with fine and coarse vertical adjustment and U1 Series SuperSpeed digital camera which operates at 100 fps.

Add the optional Oscillator to measure surface dilatational elasticity or the Environmental Fixture to measure interfacial tension. Other options included the film clamps, wafer support, and custom fixtures and specimen support options.

The fiber optic illuminator provides adjustable backlighting and each system ships with a PC and LCD to make it a complete turn-key ready-to-use instrument.

With DROPimage Advanced software, results can be logged and reports can be generated using myriad options. Images and videos can be captured and saved; high speed measurements can be taken real time at 100 frames per second or 210 frames per second with the high-speed upgrade kit.

If you need a robust automated system that is powerful and expandable, the Model 590 is well-suited for all types of contact angle, surface energy, surface tension, interfacial tension, wetting, roughness, absorption, spreading, cleanliness, and surface heterogeneity and characterization applications.

There is only one choice when the best is called for. Model 590 is a wise choice for research environments where a demanding system with a powerful suite of hardware and software tools permits the discovery of many quantitative surface characterizations with a high degree of automation and repeatability.
