Fifth International Symposium on Contact Angle

This year the Fifth International Symposium on Contact Angle, Wettability, and Adhesion will be held in Toronto, June 21-23, in conjunction with the Tenth International Symposium on Particles Adhesion and Removal held just prior from June 19-21 at the same venue. Participants of both symposia will be together on June 21 for topics that are interest to both contact angle and surface cleaning communities. We are proud to announce that ramé-hart instrument co. will be participating as an exhibitor and sponsor -- and we look forward to seeing you there on the June 21-23.

The symposium is dedicated to students, scientists, and researchers who seek to better understand the practical and theoretical aspects of surface energetics through contact angle measurements. Topics that will be covered include contact angle behavior in particle, fiber and other porous systems, contact angle and wettability in biological systems as well as in adhesion performance, measurement methods and tools, the super-hydrophobic effect, and myriad other topics relating to contact angle, measurement methods, and wettability.

Prior symposia have been held in Philadelphia (June 2004), Providence Rhode Island (May 2002), Newark New Jersey (June 2000), and San Francisco (June 1992). The first symposium was held in conjunction with the American Chemical Society meeting and in honor of Professor Robert Good. During his opening remarks at the first symposium, Professor Good reviewed the history of contact angle science starting with Galileo who, in the 17th century, may have been the first modern scientist to observe contact angle and surface energy with his study of a thin leaf of gold suspended on a surface of water.

Dr. Kash Mittal is the director of MST Conferences, the symposium organizer. Dr. Mittal is the editor of the Journal of Adhesion Science and Technology and has been the editor for over 75 books on contact angle, adhesion, interface science, surface cleaning, particle adhesion and removal, surfactants, and high temperature polymers. He has been honored by the global surfactant community with the recent inauguration of the Kash Mittal Award in the honor of his many contributions to the field of colloid and interface science.

The director of the Fifth International Symposium on Contact Angle, Wettability, and Adhesion is Dr. Robert Lacombe. He is a pioneer in the field of materials characterization and has significant experience with stress buildup in laminate structures and using the techniques of fracture mechanics to solve problems of delamination and cracking in composite materials. In addition to his 430-page volume Adhesion Measurement Methods: Theory and Practice, he's responsible for over 40 publications and patents.

Numismatic Authentication
Last month our feature article discussed the use of surface science in the authentication of numismatic pieces. We received a lot of feedback. Thank you all for your comments. In the event you missed it, it can be found in our newsletter archive here: http://www.ramehart.com/goniometers/newsletters/2006-04_news.htm As mentioned in the article, the techniques outlined are still in development and we hope to complete a standardized method that will increase the accuracy of authentication.

Interestingly, one of our readers suggested the use of X-Ray Fluorescence (XRF) Spectroscopy  technology for quantitative metallurgical analysis. We found this technology to be quite interesting although significantly more costly than surface energy analysis. If you are interested, you can learn more about one such device that uses XRF to measure the composition of metals: http://www.microphotonics.com/EDX600.html 

Product of the Month - Model 200
The ramé-hart Model 200 (p/n 200-00) is our best selling instrument. It is popular with universities and researchers who demand high performance within a budget.


This tool is a complete turn-key solution and includes a new PC, 17" LCD, our DROPimage Standard software, camera, interface, 3-axis stage, fiber optic illuminator, microsyringe and fixture, needle, and all necessary cabling. It is available in 120V and 220V versions. The DROPimage Standard software is ideal for contact angle measurement and surface energy analysis but can easily be upgraded to our DROPimage Advanced program which includes tools for surface and interfacial tension as well. The most popular option is our software-driven Automated Dispensing System (p/n 100-22-100). Approximately 60% of Model 200 sales will include the automated dispenser. Other popular options include our Environmental Fixture (p/n 100-07-60), Tilting Base Assembly (p/n 100-06), and Film Clamps (p/n 100-15) for working with thin substrates.

Each of dozens of parts are meticulously machined to exacting specifications in our state-of-the-art machine shop. After finishing, anodizing, and silk screening, the parts are hand assembled by a master instrument craftsman with over 40 years of experience working with high tolerance instrument assemblies. The camera is installed and precisely leveled. The illumination chamber is hand-painted inside and assembled. All systems are fully setup, tested, and burned in according to our rigorous standards prior to shipment. Our slides, ways, and rails use impregnated materials which do not require any lubrication maintenance by the end-user. All parts are designed to withstand 30-40 years of active use. We recommend factory service and recalibration every 10-15 years.

The Model 200, like all of our instruments, comes with a 1-year parts and labor warranty (which is rarely needed) and one year of priority software and technical support via phone or email.

If you are interested in our Model 200, would like a quotation, or a copy of our Model 200 PDF brochure, please contact us.


Thank you for your feedback. We appreciate all of our loyal customers and work hard each day to provide total customer service to each one of you.
