SFT-D2 dynamic contact angle surface tension

The new fully automatic surface tension meter is a high-level interface chemical analysis instrument specially designed and manufactured to meet the high-precision control needs of users in the field of interface chemistry testing research and quality.

A complete combination of physical performance indicators for characterizing liquids and solids in the field of surface chemistry has been conducted. Surface tension (ST)/interfacial tension (IT) testing can be conducted. Analysis and testing of contact angle (CA) for solid materials, powders, and fibers. Measurement of critical surface micelle concentration (CMC). Measurement of liquid density (g/ml) and measurement of object mass (g).

The SFT-D series surface tension analysis system is based on the open software design concept and a modular electrical structure. Exquisite appearance, lightweight and flexible, easy operation, precise measurement, and reliable quality,

SFT-D2 dynamic contact angle surface tensionFeatures:

1. High precision and high stability sensors

2. The high-precision sample stage lifting control system has a repeatability accuracy of up to 0.5um.

The SFT-D series interfacial tension meter adopts optical precision grinding screw control components to control the smooth operation and high positioning accuracy of the sample stage.

3. One click zeroing function, fully automatic measurement, simple and fast operation, minimizing human error as much as possible.

Whether analyzing surface tension, interfacial tension, or contact angle, critical micelle concentration, the D series interfacial tension meter provides a fully automatic measurement method, greatly improving the repeatability of measurement values and reducing the occurrence of human errors.

4. Multiple measurement methods provide you with comprehensive interface chemical performance experimental solutions.

The new series of surface tension meters provides you with two standard surface tension/interfacial tension testing methods: platinum plate method (hanging plate method) and platinum ring method; After selecting the corresponding modules, we provide you with solid material hydrophilicity analysis methods based on weighing, such as Wilhelmy contact angle analysis, fiber contact angle analysis, and powder contact angle analysis. At the same time, we provide proprietary A3/A4/A5 surface tension testing methods from Hako. Can compare data and methods with imported products.

5. Self calibration function, comprehensively improving the reliability of testing

SFT-D has instrument sensor calibration function, allowing you to more effectively control the reliability of measured values.

6. Automatic search function for liquid level lines.

7. Powerful database management capabilities

SFT-D provides powerful database management capabilities, which not only save and display test data in real-time, but also search for historical data, add data directly to the original test report, and export all test data as Origin curves.
