Model No: HO-IAD-CAM-01A

Holmarc’s Contact angle meter Model no: HO-IAD-CAM-01A is an instrument for research as well as industrial application with motorized syringe pump for precise dispensing and with CCD interface for measuring contact angle of liquids on solid. Video capturing and video image processing features are included in Holmarc Contact angle analysis software.

The surface over which contact angle is to be measured can be rotated through +/- 180 degree from its horizontal position for advanced contact angle studies 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 three 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.

The intensity of the backlight illumination, flow rate and volume dispensing can be controlled from the control panel. It is equipped with fuse for surge protection. The exhaust fan is also provided on the back panel with protection.

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.
Technical Highlights
