Model 260

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.


This system includes includes DROPimage Advanced as well as our fiber optic illuminator, Advanced 3-axis Stage with modular Leveling Stage, and U1 Series SuperSpeed digital camera which operates at 100 fps. Each system ships as a complete turn-key system with PC and LCD and microsyringe fixture for manual dispensing. Model 260 will also support the optional Automated Dispensing System and Oscillator.

The DROPimage Advanced software 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 also has a methods-based experiment design tool which can be used for contact angle, surface and interfacial tension. An unlimited number of parameters can define and drive the exact type of experiment you wish. Parameters allow for fully automated software-driven control of the optional Automated Dispensing System, Oscillator, and Automated Tilting Base options. DROPimage Advanced is particularly suited for time-dependant studies.

The Environmental Fixture can be added for performing liquid/liquid studies as well as captive bubble, inverted pendant and inverted sessile drop studies.

What’s in the box: Goniometer/Tensiometer 16″ Bench with U1 Series SuperSpeed Camera, Advanced 3-axis Stage with fine and coarse vertical adjustment, modular Leveling Stage, Fiber Optic Illuminator, PC, LCD, Cable, (1) Microsyringe Assembly, (1) 22g Straight Needle, DROPimage Advanced 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 and designing more advanced experiments for calculating static and dynamic surface and interfacial tension, advancing and receding contact angles, and surface dilatational elasticity and viscosity.
