Research based surface/interface tensiometer

The A201 research-oriented surface/interface tension meter is specially developed to meet the high-precision interface chemical testing requirements. The system achieves dynamic and static testing of surface tension (ST)/interfacial tension (IFT), solid/powder/fiber contact angle analysis (CA/DCA), and critical micelle concentration (CMC) measurement through imported micro weighing analysis balance (resolution 0.1 μ N), high-precision stepper motor displacement mechanism, and digital semiconductor temperature sensor. Support William plate method for single wire contact angle testing and Washburn method for powder wettability analysis, integrating three testing principles and data management modules.

The A201 research-oriented surface/interface tension meter is equipped with an independent control terminal and supports 8 sets of USB/RS232 interface expansion. Users can directly control the device through a portable terminal, and test data can be exported to a USB flash drive or directly connected to a printer for output. The constant temperature water bath system provides a temperature controlled environment of 130 ℃, and a high-temperature version can be customized for special working conditions. The Kono A20 series (including the A201 host system) adopts an independent modular design, and expansion units such as A202/203/204 need to be used in conjunction with the A201 host.

Characteristics and advantages of research-oriented surface/interface tensiometers

Core Technology Breakthrough: Dynamic Adsorption and Sandwich Effect Testing

• First principles based dynamic adsorption analysis:
  Support the precise testing of dynamic adsorption process of surfactants and liquid-liquid solid sandwich effect, breaking through the limitations of traditional platinum plate method relying on empirical models.

• Industry pain point solution: The traditional platinum plate method cannot capture the interface behavior of dynamic adsorption systems in real time (such as surfactant adsorption rate, interface relaxation). This equipment has a technological gap through high-precision sensors and dynamic algorithms.

1. High precision hardware system

• One hundred thousandth microanalysis balance:

  • The data collection rate reaches 90 times per second, and the ability to capture details is improved, making it suitable for high-sensitivity testing of single fibers, powders, LB films, and other materials.

  • Temperature drift correction, zero tracking, and built-in weight self calibration function ensure data reliability.

• Displacement control system:

  • The direct coupling design of the stepper motor eliminates the backlash of the pulley structure and achieves a positioning accuracy of micrometers.

  • USB 2.0 communication interface has strong compatibility and is suitable for new computer devices.

2. Optimization of anti-static technology

• Ion wind and ion beam technology:

  • Eliminate static electricity interference on the liquid surface and solve measurement errors caused by liquid level positioning deviation (such as false high tension caused by rising liquid level).

  • Continuous static elimination function, suitable for testing materials such as powders and fibers that are prone to static electricity.

• Anti static glass door: blocks external static charge conduction and improves the stability of the testing environment.

3. Multi functional software module (CAST) ® 1.0）

• Dynamic and static tension testing:

  • SM01 module: supports platinum plate method, platinum ring method, and suspended plate method, dynamically correcting contact angle and buoyancy effects.

  • SM08 module (LB film and interface rheology): Analyze interface viscoelasticity, dynamic expansion/oscillation behavior.

• Surface active agent research:

  • Real time monitoring of CMC (critical micelle concentration), surface excess, and Gibbs adsorption free energy.

  • Database management: Automatically saves dynamic curve data, supports historical record queries, corrections, and exports (in Excel format).

• Wettability and surface free energy analysis:

  • The liquid library contains 300 types of liquids and 800 sets of data, which can quickly calculate components such as polarity force, dispersion force, hydrogen bonding force, etc.

4. Industry testing scenario adaptation capability

• High viscosity sample testing:

  • The non-invasive platinum plate method supports tension testing of high viscosity samples (≤ 10000CP) such as glycerol, ink, and resin.

• Temperature conditions:

  • The constant temperature sample pool covers the range of -40 ℃ to 250 ℃, suitable for melt and high-temperature reaction systems.

• Special material testing:

  • Single fiber tensile strength, powder permeability, nanoparticle settling analysis, and providing extended solutions such as Thin Layer Wicking.

5. Humanized design and compatibility

• One click operation and pre wetting function: simplifies the testing process for oily substances and reduces human error.

• Multilingual interface (Unicode technology): Supports switching between Chinese, English, and * languages.

• Modular accessory system:

  • Provide optional accessories such as LB membrane tank, magnetic stirring constant temperature bath, anti-static device, etc., to meet complex experimental needs.

  • Density testing module: supports solid/liquid density measurement.

Complies with international standards

• ASTM D971, ISO 1409: Oil water interfacial tension, plastic/rubber dispersion surface tension testing.

• ISO 4311, BS EN14370: Determination of CMC and tension analysis of surfactants.
