Contact Angle Meter

DMe-211

The DMe-211 is an economical yet fully-featured contact angle meter with a computer image analysis system.

The unit combines manual droplet volume regulation, and stage up/down motion for gentle deposition of droplets with "FAMAS-basic" software controlled analysis of static and dynamic contact angle (30fps) as well as surface and interfacial tension using the pendant drop method. Analysis software to determine the surface free energy of solids is a standard feature.

PCA-11

The portable contact angle meter PCA11 is a compact and lightweight device for fully automated on-site measurements of contact angle, surface tension, and surface free energy of solids. Testing on-site for quality control and evaluation of surface wettability, which is characterized by the contact angle, is often required during manufacturing processes or in the field. The PCA-11 can be used on any material such as glass, metal, film, paper & pulp, polymer, wood, etc. that have to be measured on-site or that due to their size or shape cannot be analyzed with the usual stationary contact angle measuring instruments. Weighing only 650g, combined with the single-click fully automated operation and its precise measurements, the PCA-11 is the ideal solution for non-destructive surface evaluations.

Features
  • Single-click fully automated operation
  • Precise measurement of contact angles, even on slopes of up to 90º
  • Analysis of surface free energy
  • Measurement of surface tension using the pendant drop method
  • Time-dependent measurements by image capture of up to 30 fps

FPD-CP11

The FPD-CP11 system consists of the main measuring head, a metering pump with a 50mL capacity liquid container, and a control box, and it has been developed for non-contact measurements of contact angles on flat panel displays such as LCD, LED, OLED, and silicon wafer. It has been designed to be attached to metrology systems that combine several different measuring devices in one system. The communication and data transmission between this host system and our FPD-CP11 is achieved via an RS-232C serial port connection.

The system is specially designed to observe droplets with a lateral image capturing system and the optical system is set at a slight angle, making it possible to measure contact angles without having contact with the panel's delicate surfaces. Thanks to this lateral image capturing system, the FPD-CP11 is not limited to only 90º, such as top-view measuring systems, but instead, it delivers high-accuracy and reliable measurements in a range from about 3 to 175º.

Features
  • Single-click automatic measurements, to be operated from a host system
  • Precise and reliable measurement of contact angles from about 3 to 175 degrees
  • Time-dependent measurements by image capture up to 30 fps
  • Metering pump, incl. a 50mL liquid container, allowing 50,000 1μl droplets with one prepared liquid container
  • Droplet calibration standard for standard view, bearing one full circle for calibration and three droplet silhouettes of 5º, 60º, and 108º for periodic inspection of measurement accuracy
Options
  • No options are available for the FPD-CP11, but customized solutions are possible to adapt the FPD-CP11 to existing metrology systems
Applications
  • Contact angle measurements to determine the surface cleanliness of flat panel displays such as LCD, LED, OLED and silicon wafer
