The ramé-hart Model 250 Standard Goniometer / Tensiometer is a powerful tool for measuring contact angle, surface energy, surface tension, interfacial tension, and surface dilatational elasticity and viscosity (with optional Oscillator). Model 250 is a popular model with researchers due to the wide spectrum of demanding tasks it can perform. This tool is affordable yet powerful, capable of gathering data as accurately and precisely as tools costing two to three times as much.
The ramé-hart Model 260 Standard Goniometer / Tensiometer is identical to Model 250 except for one feature: Model 260 includes the Advanced 3-axis Stage with fine and coarse vertical adjustment and modular leveling stage while Model 250 has the standard 3-axis leveling stage. With the Advanced 3-axis Stage, Model 260 supports the optional Environmental Chamber and Temperature Controller allowing for experiments at elevated temperatures.
The ramé-hart Model 290 Automated Goniometer / Tensiometer offers a powerful level of automation and a wide array of software tools. The system includes our software-driven Automated Tilting Base 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. Model 290 also includes our most capable edition of DROPimage, DROPimage Advanced with the capacity to design powerful experiments which may include drop volume and tilt control.
The Model 400 Goniometer with Wafer Support has been designed uniquely for the semiconductor industry. This model shares components including the standard 3-axis stage with the Standard Goniometer, as well as the long bench of the Advanced Goniometer. This system includes an 8″ (200mm) diameter rotating wafer support which can be upgraded to 10″ or 12″ or 13.625″ or even fitted with a 6″ or 4″ support. 6″ and 8″ diameter vacuum chucks are also available as an option. Additionally, custom support options can be built to customer requirements.
The Model 500 Advanced Goniometer / Tensiometer includes a vast array of capabilities. In addition to shipping with DROPimage Advanced, the Model 500 is capable of accepting every modular accessory available from ramé-hart. This permits the building of a sophisticated tool which can be optimized for specific applications and research environments.
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.
The ramé-hart Model 790 represents the most advanced and automated tool available. This system includes automated tilting, automated dispensing, high-speed video with the G1 Series GigE (Ethernet) camera (210 fps), environmental control from -50° to +300° C, overhead imaging, and oscillation hardware. Coupled with DROPimage Advanced software, this setup ships ready to measure static contact angle, dynamic contact angle, advancing and receding contact angle, contact angle hysteresis, surface energy, work of adhesion, surface tension, interfacial tension, surface dilatational elasticity and viscosity. The methods-based experiment design tool offers unlimited configurations for a wide variety of studies including wetting, roughness, absorption, spreading, cleanliness, and surface heterogeneity and characterization at ambient, chilled, or elevated temperatures.
