Model No: HO-IAD-CAM-01

Holmarc’s Contact angle meter Model no: HO-IAD-CAM-01 is a basic educational equipment for illustrating the basics of contact angle measurement to students. It has manual dispensing with CCD 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 opto-mechanics, high-resolution CCD detector and associated electronics used in our instrument guarantee error free measurements. The intensity of the backlight illumination can be controlled in the control box.

The surface over which contact angle is to be measured can be rotated through +/- 180 degree from its horizontal position for advanced contact angle study and to find out contact angle hysteresis.

The wettability of a droplet is also dependent on the substrate in contact with the liquid. We provide 3 different substrates along with the equipment - made of aluminium, brass and stainless steel. However, the substrate according to customers’ choice can also be loaded into the equipment.

Standard off the shelf syringes can be integrated from 0.4 to 20 ml, from any manufacturer. The equipment is compatible with glass, plastic and SS syringes. Three chromatographic syringes with 50 micro litre, 100 micro litre and 250 micro litre capacity are supplied along with the equipment.

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.
