KRUSS DSA30 E droplet shape analyzer
Automated analysis of wetting processes and adhesion forces between liquid and solid phases
Product Introduction of KRUSS DSA30E Droplet Shape Analyzer
The DSA30E expert level droplet shape analyzer can highly automate the analysis of the wetting process between liquid and solid phases. The high degree of automation and ease of programming enable users to independently analyze results based on contact angle and surface tension, making it an ideal choice for quality control. On the other hand, due to the versatility of DSA30E in temperature control and the scientific nature of solid-liquid contact angle analysis, DSA30E is often used in the research and development field.
KRUSS DSA30E droplet shape analyzer product application:
Quality assurance for activation processes, such as plasma treatment, corona treatment, or flame treatment
Determine the wettability of plastics, glass, ceramics, wood, paper, or metal
Analyze the effectiveness of hydrophobic coatings and other coatings
Analyze the coating liquid and adhesive, evaluate their adhesion strength
Evaluate the long-term stability of the coating
Analyze (super) hydrophobicity and self-cleaning surfaces
Analyze the uniformity of cleanliness and wettability, and measure the differences between coated/uncoated or treated/untreated areas
Wetting analysis under controlled temperature and/or humidity
KRUSS DSA30E droplet shape analyzer measurement method:
Contact angle of liquid droplets on solid surfaces
Parallel dual droplet contact angle
After drawing the preset position, the software automatically measures the contact angle of the corresponding position in batches, and then performs surface evaluation
Measure the contact angle between the bottom of the solid material immersed in the liquid phase and the bubbles
The forward and backward angles of droplets when rolling off a sloping surface
Calculate solid surface energy through contact angle data
Calculate the adhesion related scientific parameters of interface contact
Measuring surface or interfacial tension using the curved contour of liquid suspended at the bottom of the needle
Calculate surface tension by calculating the curvature of symmetrical droplets formed on a circular sample base
Calculate the polarity and non polarity of surface tension from contact angle and surface tension data
The contact angle immersed in the liquid of a cylindrical sample pool, typically consisting of fibers
Perform up to 20 consecutive measurements and display the results together
Remote control of ADVANCE for integration into customized automation systems
Measure the current setback angle to characterize the de wetting behavior

Up to four solid-liquid analyses can be performed
The DSA30E is equipped with a software controlled three-axis automatic sample stage, which can quickly and accurately move the sample to the preset measurement position, making it an ideal choice for high-throughput standardized quality testing needs. In addition, the instrument can also analyze the wettability of the sample based on its preset position to check the uniformity or evaluate the differences between the coated and uncoated areas.
Automatic positioning for comprehensive sample analysis
The fine-tuning manual sampling module of DSA30E can accurately adjust the droplet volume to obtain results with good comparability. This ensures high reproducibility of droplet size and allows for good comparison of results. The replaceable syringe can quickly switch between different liquids, enabling high-throughput testing.
High imaging quality, reliable droplet shape analysis
The DSA30E has a high-resolution camera and high-quality zoom lens, which can accurately display the optimal size of droplets. High quality image quality can accurately measure contact angle or surface tension (SFT). The intelligent image evaluation algorithm combined with ADVANCE software can provide accurate results for droplet shape analysis using this instrument.
Maximizing the repeatability of measurements and comprehensive adhesion analysis
The automated program that is easy to create with the help of ADVANCE software can also be used to design standard programs for sample analysis, in order to maximize the repeatability of measurements. The optional software tool for data analysis combines SFE and SFT data to evaluate adhesion and calculate other scientific parameters of solid/liquid contact.
