DMs-401
The DMs-401 is a compact yet high-performance surface measuring instrument for the measurement of static and dynamic contact angles, surface free energy of solids and surface and interfacial tension of liquids. Its functions can be easily extended due to its sophisticated modular design. Optional accessories, such as a computer-controlled dispenser, temperature control devices, and an external tilting stage system are available.
Features
- Automatic recognition of droplet deposition
- Live image display and droplet volume monitoring
- Movie converter
- Manual dispenser with a set of 5 glass syringes and 5 SUS needles for precise adjustment of droplet volume and quick refilling and replacement of liquid samples
- Fine adjustable stage in z-axis for gentle deposition of droplets without distortion
- Adjustable level of the body and stage
- 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
