The ramé-hart Model 250 Standard Goniometer/Tensiometer is a powerful tool for measuring contact angle, surface energy, surface tension, interfacial tension, and surface dilatational elasticity and viscosity. Model 250 is a popular model with researchers due to the wide spectrum of demanding tasks it can perform. This tool is affordable yet powerful, capable of gathering data as accurately and precisely as tools costing two to three times as much.

This system includes includes DROPimage Advanced as well as our fiber optic illuminator, 3-axis specimen stage with leveling, and high speed F4 Series digital camera. Each system ships as a complete turn-key system with PC and LCD and microsyringe fixture for manual dispensing. Model 250 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.

Add an Environmental Fixture to perform 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 F4 Series Camera, 3-axis Leveling Stage, and Fiber Optic Illuminator, PC, LCD, FireWire 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.
