Profile: Rame-Hart Instrument Co., LLC specializes in surface science instruments. Our products include goniometer, tensiometers, automated dispensing system, oscillator, automated tilting base, and calibration tools. Our Goniometer/Tensiometers are used to measure contact angle, surface energy, surface tension, and interfacial tension. We offer four different instruments for measuring contact angle, surface energy, and surface and interfacial tension. Our automated dispensing system (p/n 100-22) is a software-driven tool and control pump for creating single drops or dynamic drops, such as required by advancing and receding, and other dynamic studies.
