HPHT Interfacial Tension Measurement
The Grace Instrument M6550 HPHT Spinning Drop Tensiometer measures low interfacial tension at elevated temperature and pressure. The unit features a microscope that magnifies up to 25x with a numerical display resolution of 0.0001 mm, offering researchers the greatest measurement accuracy of any comparable device on the market today. The M6550 instrument features a unique, patented design.

High-Resolution Microscope for Enhanced Accuracy
The unit was developed for the measurement of interfacial tension, surface tension, adsorption rate, and extremely low interfacial tension. Excellent temperature control and optimum synchronization of the instrument allows the sample to be observed over a long period of time under constant conditions.

Lightweight and Easy to Handle
The M6550 weighs only 40 lbs. and includes a level-adjustment control with handles on its two sides. This allows the user to easily pick up, travel with, and/or manipulate the unit to reposition the test droplet quickly and efficiently.
