Category: Contact Angle Measurement

Water contact angle (WCA) describes the shape a droplet of water forms when placed on a surface. If the water spreads out, the water contact angle is low. If it beads up, the water contact angle is high. This matters because the way a liquid wets a surface strongly affects processes such as adhesive bonding, […]

As medical device designers and manufacturers, you often depend on the property wetting, which can lie at the heart of your product’s reliability. Wetting determines two critical things: How well your adhesives, inks, or coatings adhere – ensuring structural integrity and compliance How effectively your coatings perform – from hydrophilic lubricity to hydrophobic protection In […]

Our partners Biolin Scientific are running a webinar entitled Optimising Biomedical Device Coatings: The Power of Contact Angle Measurements. Delivered by Dr Susanna Lauren, Biolin’s Marketing Director for the Attension brand, it will explore the critical role of contact angle measurement in the development and performance of medical device coatings. This session will guide you […]

A sessile drop refers to a liquid droplet that’s placed on a solid surface. The term stems from Latin sessilis, meaning “sitting,” emphasising that the drop remains stationary on the substrate. It’s literally attached at its base, offering a stable configuration for optical analysis. The sessile drop method is a technique we very commonly use for […]

Contact angle – What is it and how do you measure it? is a White Paper written by Susanna Laurén of our partners Biolin Scientific. Understanding how liquids interact with surfaces is essential in many of your research projects and industrial processes. Contact angle measurement is one of the most widely used methods for studying […]

A Wilhelmy plate is a thin plate used to measure the surface tension or interfacial tension of a liquid. The plate’s dimensions are usually on the order of a few square centimetres, with a thickness of ~0.1 mm – very thin to minimize buoyancy effects and to ensure high sensitivity. It is made from an […]

Since Dyne Testing Ltd was acquired by Intertronics, our interest in – and understanding of – surface science has expanded past surface measurement to adhesion, adhesive performance and surface treatment. We’ve combined all of our aspects on surface treatment, surface measurement, and surface preparation into one place, alongside some relevant products. Have a look at […]

Today, we’re talking about surface science – specifically about tensiometers – courtesy of Alison. She explains: What tensiometers are able to measure Different types of tensiometers, such as force tensiometer, bubble tensiometer, or optical tensiometer (also known as contact angle meter) Check it out!   You can find out more about specific types of tensiometers […]

Surface cleanliness is an important topic in many industrial areas, it is especially needed in applications such as coating, painting or printing where something is added on top of the other material. If the surface where the coating is applied to is not clean, the adhesion between the coating and the substrate is typically poor.  […]

We are proud to present you the extension to our Theta optical tensiometer family.  The Attension Theta Flow has automation at an all-time high, accuracy not seen before and remarkable simplicity & ease of use.
