Most advanced droplet analyzer - Smartdrop

The application "Free-surface goniometry" was developed by FEMTOFAB for the first time in the world!

 

Contact angle, surface tension simultaneously measured for the first time in the world!


>> What is free-surface goniometry?

It is the calculation method of contact angles only by FEMTOFAB where the free surface (without distortion) is measured excluding the surfaces of liquid droplet with interface distortion and optical distortion to obtain accurate values by reversely calculating the distorted contact surface.

Free-Surface Goniometer (FSG) "SmartDrop"

 

 1. Application of free-surface goniometry (FSG) developed for the first time

     in the world

 

  - GEM engine is applied where gravity-driven deformation of interfaces is

     accurately analyzed numerically.
  - Contact angle is measured using only free-surface domains without any distortion.
  - The most ideal measurement of contact angles completely excluding fundamental
    distortions (interface distortion, optical distortion) near the contact line.

  * With existing approximate algorithms, errors greater than 10° occurs

     in superhydrophobic domains.
  * Single algorithm measurement for the whole domain: All of accuracy, repeatability,
     convenience maximized because there is no need for selection of an algorithm.

2. Calculation of surface tension simultaneously with measurement of contact angle.

  - Super-high precision measuring instrument of surface tension that is very convenient

     to use.
  - Pollution or deformation status of water used in contact angle measurement may

    be  always affirmed.

3. Sealed-type case shutting off external influence and real-time

                                                                                   temperature/humidity monitoring

 

  - Excellent performance in evaporation-related studies such as printed electronics,

    DNA chip, semiconductor cleaning, etc.
  - Ready application for high-difficulty measurements and experiments requiring  

    suppression of evaporation owing to provision of high-humidity environment.

4. Dynamics measurement: Measurement of contact angle hysteresis based on

    vibration-free tilting

 

  - One-click all-automatic measurement: Automatic setting of rotation speeds, measurement
    intervals.
  - Real-time outputting in graph of advancing angles and receding angles: Transient-period
    hysteresis analysis.
