The integrated instrument consists of sophisticated optical mechanism, optical vision system, high-precision dosing system as well as CAST 3.0-USA KINO’s professional interface chemical analytical software. SL200K series are applicable to measure static / dynamic contact angle, surface free energy of solid and its distribution (dispersive force, polar force and hydrogen bond force, etc.), interface tension of liquid-gas / liquid-liquid as well as interface viscidity & elasticity of liquids (oscillating and expanding drop), etc. We provide clients cost-effective instruments with best performance - the most professional high pressure contact angle meter & interfacial tensiometers and technical assurance in R&D and quality control.
What’s High Pressure Contact Angle Meter?
high pressure contact angle meter is defined as the angle between tangent of gas-liquid interface and that of solid-liquid interface formed at the three phases’ boundary where liquid, vapor and solid intersect.

USA KINO makes comprehensive analysis of both merit and demerit of various high pressure contact angle meter around the world. And SL200K series are our update products in terms of long-term experience in R&D and on-site production. For the purpose of cost control and performance improvement, comprehensive optimization has been made in mechanism and optical system; Software design to maintain movement of sample stage and lens stability and to provide high definition and performance images.
More accurate, stable and diversified mechanical system
1. Precision positioning stage, linear guide, screw technology used in mechanical system, with precision up to 0.01mm by manual and 0.5μm by software control respectively.
2. Uniquely-designed mechanism of up to 10 axis control (6-axis linear adjustments +1 rotation adjustment + 3 horizontal adjustments), coordinate the operation of sample stage, lens, camera and dosing system.
3. Zero-backlash and low error on-axis optical positioning stage guarantees stability, repeatability and exceptionally smooth motion.
4. Professional high-precision syringe pump system with accuracy of droplet control down to 0.02μL or even nL (optional), which can be applied to high-precision repetitive liquid dosing.
5. Flexible focus control system and micro distance of needles moving (about 0.01mm) makes more accurate and easier operation of transferring drops, especially for super-hydrophobic biomimetic material surface test.
6. Integrate designed instrument with mainframe made of high-grade aviation aluminum guarantees its handiness and fastness.
More professional and comfortable design of mechanism
1. Unique mechanism of fixed focal distance and high-precision adjustable positioning stage, with easier and more accurate focal distance obtaining and clearer image shape.
2. Integral rotation system controlled by rotation positioning stage, enabling sample stage to rotate with lens in order to hold drop image in field of view during capture process. The unique design makes accurate analysis of roll off contact angle possible without hard operation and bad precision when rolling the entire instrument, as well as avoiding drop disappearing from the field of view when partially rotating. Besides, just a simple switch can enable of sample stage rotating only. (Manual and electronic tilting base for option).
3. Soft light plate made of frosted quartz glass achieves clearer, sharper and softer background light and better drop shape.
4. Unique design of syringe replaceable direct dosing system makes it easy to hold KINO’s OEM syringe or special syringe with PTFE needle, ultra-thin needle (OD:0.23mm) for measuring hydrophobic material and syringe measuring medium / high viscosity sample.
5. System with four levelness adjustment units:
Except one complete machine levelness adjustment via quadrupled tuning knob and one precision tilting angle adjustment of lens and camera via 1 axis tilt platform stage with micrometer, we provide one multi-axis tilt platform with micrometer to adjust the levelness of sample stage and one zero-backlash rotation stage to roll the sample stage. All these guarantee the accuracy of base line detection and the measurement of roll-off contact angle.
6. Adjustment both by hardware and software with better base line detection.
The levelness adjusting mechanism, illumination-adjustable LED cold light source as well as CAST® 3.0 software system provide you strong assurance of better base lines detection, and more convenient measurement of roll-off contact angle and advancing/receding contact angle.
Sharper edge and high-speed optical vision system
1. Illumination-adjustable cold LED light source technology with sharper and clearer drop contour profile shape, effectively avoiding drop evaporation caused by excessive heat.
2. Higher quality camera with speed of 87-340FPS made in Germany (standard WVGA format). (Optional with cameras of 130M, 300M, 500M)
3. Continuous-zoom industrial lens of high-magnification, with range of magnification 0.35-4.5X.
