Contact Angle Meter
Model: HO-IAD-CAM-02
Price : $ 5,000.00

Holmarc’s Contact Angle Meter is a compact and cost-effective CMOS based instrument for measuring contact angles of liquids over solid substrates. It has automatic dispensing unit with camera interface for measuring contact angle of liquids on solid surfaces. The surface over which contact angle is to be measured is held in horizontal position to find out contact angle using sessile drop method. State of-the-art optics, precise optomechanics, high-resolution CMOS detector and associated electronics used in our instrument guarantee stable and accurate measurements. The illumination intensity of the back light LED can be controlled. The surface over which contact angle is to be measured can be rotated through 180 degrees from its horizontal position for advanced contact angle study and to find out contact angle advanced/recede angles. The wettability of a droplet is also dependent on the substrate in contact with the liquid. The equipment is compatible with glass, plastic syringes. Chromatographic syringes with 50 micro litre, 100 micro litre and 250 micro litre capacity are supplied along with the equipment.

Holmarc’s Contact Angle Meter is a versatile instrument widely used in both research and industrial applications. It measures the contact angle of liquids on solid surfaces, which is crucial for understanding the wettability and surface properties of materials. These information’s is essential in fields such as material science, coatings, and surface engineering, where the interaction between liquids and solids plays a significant role in product performance and quality. By measuring the contact angle, researchers can determine the hydrophobicity or hydrophilicity of drug coatings, which affects the release rate and absorption of the drug in the body. Contact Angle Meter is used in the development of advanced materials, such as superhydrophobic surfaces and self-cleaning coatings. These materials have applications in various industries, including automotive, aerospace, and construction, where reducing surface contamination and improving durability are critical. By accurately measuring contact angles, researchers can optimize the design and functionality of these innovative materials.

More +

Contact angle is the angle formed by a liquid at the phase boundary where a liquid, gas and solid intersect. The shape of the drop is controlled by the three forces of interfacial tension. Static Angle and Advancing Angle are quantitative measures of the wetting of a solid by the liquid, but they can also be used as a quality control measure in surface treatments and surface cleanliness. Receding Angle is a quantitative measure of the adhesion of a solid to a liquid.
