Since 1961 ramé-hart instrument co. has been the world leader in surface science instruments. Not only are we the first company in the world to mass produce a contact angle goniometer, we remain the only company dedicated solely to contact angle and surface tension instruments. Our innovative approach allows us to stay nimble and flexible. Our current generation of tools measure static and dynamic contact angle, drop dimensions, surface energy, work of adhesion, surface and interfacial tension, and with the appropriate accessories, advancing and receding contact angle, roll-off angle, contact angle hysteresis, surface dilatational elasticity, relaxation, absorption, cleanliness, wettability, adhesion, and the quality and efficacy of surface treatments and modifications. In addition to instrument sales, we perform lab work and build custom instruments for special applications.
