|The New Model 295 Automated Goniometer / Tensiometer|
This month we are pleased to announce the
debut of our new
Model 295. This
new offering shares many of the same qualities of
For example, both models include the powerful
Automated Dispensing System for improving drop dispensing accuracy,
Automated Tilting Base for performing advancing and receding contact
angle measurements, and the powerful
Advanced software. What sets the Model 295 apart is the Advanced
3-axis Stage with fine and coarse vertical adjustment and modular
leveling stage. This more advanced setup allows for support of a wider
array of modular options such as the
Environmental Chamber with temperature control up to 300° C, the
Environmental Fixture for performing liquid/liquid and captive
bubble studies, or the Oscillator for measuring surface dilatational
elasticity. (Note that Model 290 will support the Environmental Fixture
and Oscillator also - but not the Environmental Chamber and Temperature
Model 295 is well-suited for demanding research environments which require maximum out-of-the-box capability while offering the widest spectrum of upgrade options for more specialized applications. To learn more, visit this page http://www.ramehart.com/295.htm.
UPDATE: EFFECTIVE 1-JAN-2015 MODEL
295 HAS BEEN DISCONTINUED. THE SAME CONFIGURATION IS CURRENTLY AVAILABLE
BY PURCHASING MODEL 290 AND ADDING THE ADVANCED STAGE UPGRADE KIT.
|The Commercialization of Hydrophobicity|
The only thing more challenging than
developing cutting-edge nano-coating technology is selling it for a
profit. Increasingly, however, companies are taking on the task of
commercializing new hydrophobic coatings which not only benefit their
bottom line but add value to their customers' products.
A company based in the United Kingdom, P2i Ltd., for example, offers a variety of nano-coatings which make products liquid repellent without altering their appearance or function. Their ion-mask product, for instance, adds an ultra thin protective layer to products such as footwear adding water repellency while maintaining breathability. They claim the nano-coating is physically bonded at the molecular level and consequently will last as long as the base material itself without degradation from everyday wear.
Fabrics can also be treated with the ion-mask coating rendering them water-repellent and adding a level of stain resistance without altering the character and feel of the material. Many other products, from eyewear to backpacks, could potentially benefit from this technology.
One of the most exciting developments in nano-coating developments is the waterproofing of electronic devices. Think hearing aids, smartphones, and tablets. In February we discussed making tablets and phone screens oleophobic. However important this treatment is in making the screen easier to use and keep clean, it's of no value if the device falls in the toilet or is left in the rain and is rendered inoperable.
P2i offers a product called Aridion which consists of a super-thin invisible nano-polymer coating which - when applied to a cell phone, for example - produces a hydrophobic skin which repels water, is bonded at the molecular level, and does not affect the look and feel of the device. However nice this is, the treatment only protects against splashes, not submersion.
Two companies have developed even more advanced nano-coatings which protect against both splashes as well as underwater events. HzO offers a WaterBlock technology which is applied using a vacuum deposition process. And Liquipel, using a similar technology, coats not only the outside of the device, but internal components as well. For as little as $59, they will treat a smartphone or MP3 player with their nano-coating product. Liquipel is marketed as protection against accidental water exposure and includes no device replacement guarantee.
If you are developing or testing
nano-coatings such as the ones mentioned above, there remains one tool
for characterizing hydrophobicity: the contact angle goniometer. To

ramé-hart was founded in 1961. This year
we celebrate our 51st birthday. Below is a picture of some of the
original employees. Ralph Nussbaum, George Meyer (not

ramé-hart derived its name.
