High-resolution microscope for enhanced accuracy
The M6500 microscope magnifies up to 25x and enables a numerical display resolution of 0.0001 mm, giving the researcher the greatest measurement accuracy of any comparable device

Light-weight and easy to handle
The M6500 weighs only 24 lbs. and includes a level adjustment control and handles on two sides. This allows the user to pick up and manipulate the unit in order to reposition the test droplet quickly and easily.

 The Grace Instrument M6500 Spinning Drop Tensiometer was developed for the measurement of interfacial tension, surface tension, absorption rate and extreme low interfacial tension. Excellent temperature control and optimum synchronization of the instrument allow the sample to be observed over a long period of time at constant conditions.

When measuring low interfacial tension, the Grace Instrument M6500 Spinning Drop Tensiometer features enhanced accuracy compared to automatic, software-controlled units thanks to an advanced much-higher-resolution microscope than on competing models.

Features:     

• Measurement of extremely low interfacial surface tension
• Accurate RTD temperature readout
• Advanced PID temperature controller
• Accurate speed controller ensures high image synchronization
• High accuracy of reading with stroboscope illumination
• Digital read out on integrated microscope
• Light weight
• Adjustable leveling
• Optional chiller sleeve for low temperature applications
