Obtain surface free energy within seconds

The emergence of liquid needles enables contact angle measurement technology to perfectly ensure quality. Learn more about the concept of combining speed and scientificity with liquid needles.

The dual titration system ensures fast and accurate measurement of surface free energy and surface tension

The software controlled micro constant pressure double titration system equipped with DSA25E ensures fast and accurate measurement of surface free energy. Liquid needle titration technology is based on the contact angle of two liquids for rapid one click measurement of surface free energy (SFE). An additional titration system can be used to add data from a third liquid to consolidate SFE results or measure the surface tension (SFT) of the liquid.

High quality zoom lens ensures the accuracy of droplet contact angle measurement

The DSA25E has a high-resolution camera and high-quality zoom lens, which can accurately display droplets of ideal size. The high image quality achieved through this can accurately measure the contact angle or SFT. The use of instruments combined with the intelligent image evaluation algorithm of ADVANCE software for droplet shape analysis can provide accurate results.

Significantly improve the repeatability of measurements and comprehensive adhesion analysis

With the support of ADVANCE software for liquid needles, automated measurement of SFE can be completed within one second. Easy to create automated programs can also be used to design standard procedures for sample analysis, significantly improving the repeatability of measurements. The optional software tool for data analysis combines SFE and SFT data to evaluate adhesion and calculate other scientific parameters of solid/liquid contact.

	During production or transportation, the interface of droplets or bubbles is stretched, resulting in constant movement of lotion and foam. During these processes, the interface of droplets or bubbles is stretched, and surface tension or interfacial tension reacts to this stretching. The speed and degree of this reaction have an impact on the stability of food or personal care products and affect oil recovery efficiency (EOR). useDSA30R droplet shape analyzerconductInterface rheologyMeasurement can obtain key measurement results for optimizing products and processes.
