Submillimeter mapping of surface wettability with unprecedented force sensitivity.
Rapid mapping of surface characteristics by magnetic droplet scanning.
Read about our recent achievements in wetting research.
Droplet Instruments can facilitate:
- early detection of surface degradation and contamination
- optimization of coating adhesion
- understanding the effect of roughness on wetting properties
- studying ink adhesion to improve printing quality
- and more
We are a multidisciplinary team with unique expertise in soft matter (Prof. Robin Ras) and robotic instruments (Prof. Quan Zhou) working on the development of the most precise and accurate measurement techniques for surface characterization.
With a decade of academic experience in developing high-end hydrophobic surfaces for real-life applications we know the difficulties in reliable and efficient surface wetting characterization. [1-3] As such, we have developed innovative instruments for faster and more accurate measurement of liquid-solid interactions.
Extremely sensitive instrument for characterization of hydrophobic surfaces. It allows direct force measurements from hundreds of micronewton down to nanonewton range, and can map spatial variation of wetting down to micrometer resolution, for analysis of various wetting phenomena. [4-6]
We provide Scanning Droplet Adhesion Microscope as a measuring service and offer joint development of custom measuring systems with the customer.
Rapid measurement of hydrophobic surface characteristics, such as wetting properties, coating homogeneity and contamination. Scanning with the magnetic droplet allows mapping uniformity of wetting across the sample surface, even inside tubes and other closed systems.
We offer Scanning Droplet Tribometer as a measuring service for surface characterization.
