Profile: Ramé-Hart Instrument Co. specializes in offering surface science instruments. The model 190 CA goniometer is an entry-level tool optimized for simple static contact angle measurement. Model 190 includes DROPimage CA as well as our fiber optic illuminator and high performance F1 series digital camera. Each system ships as a complete turn-key system with PC and LCD & microsyringe fixture for manual dispensing. The manual tilting base option can be added for measuring advancing and receding angles, determining roll-off angle & calculating contact angle hysteresis. The automated tilting base option requires the software to be upgraded to DROPimage Advanced. The oscillator (p/n 100-28) provides precisely controlled periodic oscillatory deformation of sessile and pendant bubbles & drops in order to allow for the measurement of surface dilatational elasticity & viscosity using the axisymmetric drop and bubble shape method. Designed to sit inline between the automated dispensing system and the final dispensing tip or needle, the oscillator is motor-driven & fully software controlled using ramé-hart DROPimage v2.4 or higher software.

The company was founded in 1962, has revenues of USD 1-5 Million, has ~20 employees.
