Model 200

The ramé-hart Model 200 Standard Contact Angle Goniometer is a powerful tool for measuring contact angle and surface energy. Model 200 is a top-selling instrument and is used by researchers and scientists around the world. This tool includes DROPimage Standard as well as our fiber optic illuminator, 3-axis leveling stage, and high-speed 100 FPS U1 Series SuperSpeed digital camera. Each system ships as a complete turn-key system with PC and LCD and microsyringe fixture and assembly for manual dispensing. Model 200 supports the optional Automated Dispensing Systemand Manual Tilting Base options as well as over a dozen other accessories.


An affordable solution built on the time-proven ramé-hart design makes the Standard Goniometer popular with universities and research labs. Many customers who purchase the Model 200 later upgrade to DROPimage Advanced as their needs become more demanding. Note that if you are interested in a new Model 200 with DROPimage Advanced, you should look at Model 250 as this model is identical to Model 200 but includes the Advanced software.

The DROPimage Standard software measures contact angle and includes a suite of surface energy tools including: the Acid-Base Tool, the Surface Energy Tool, the Work of Adhesion Tool, Zisman’s Plot Tool, the Solid-Liquid-Liquid Surface Energy Tool, and the One-Liquid SE Tool. The software can be upgraded to DROPimage Advanced without any additional hardware to measure surface and interfacial tension. The Manual Tilting Base option can also be added for measuring advancing and receding angles, determining roll-off angle, and calculating contact angle hysteresis. The Automated Tilting Base option requires a software upgrade to DROPimage Advanced. The Automated Dispensing System is fully supported with or without the software upgrade.

What’s in the box: Goniometer Bench with U1 Series SuperSpeed Camera, 3-axis Stage, Leveling Specimen Stage, Fiber Optic Illuminator, PC, LCD, Camera Cable, (1) Microsyringe Assembly, (1) 22g Straight Needle, DROPimage Standard Software Single User License, Software User Manual, Setup Guide, Calibration Tool, and Storage Cover — everything you need to get up and running taking contact angle and surface energy measurements right out of the box.
