Contact Angle Measurement Tool

The contact angle meter is an ideal industrial or academic tool for product development engineers r d engineers who need precision and repeatability.

Contact angle measurement tool. You may use it for free for home development education or other purposes. Contact angle measurement system is a tool to study the wetting behaviour of a liquid on solid. Force tensiometer measures the mass affecting to the balance when a solid sample is brought in contact with the test liquid. Different methods are used for measurement which are classified as follows.

Phenomenon like spreadability absorption adsorption dissolution can be studied by contact angle measurement devices. A given system of solid liquid and vapor at a given temperature and pressure has a unique equilibrium contact angle. Double click on the pushpin will remove it. The contact angle is the angle conventionally measured through the liquid where a liquid vapor interface meets a solid surface.

It quantifies the wettability of a solid surface by a liquid via the young equation. Contact angle measurement is an empirical tool for understanding the wetting between a liquid and a substrate. It is possible to measure right acute and obtuse angles in degrees from 0 to 360 using this interactive instrument. Contact angle measurement is the preferred and most accurate method of much vital laboratory measurement and research for determining the interactions at the solid gas liquid interface.

The baseline of the measurement is the horizontal line that represents the solid on which the droplet is being deposited. Click the edge outside of the protractor will add a pushpin on it. The oca 200 is the contact angle measuring and drop contour analysis system for microscopic and macroscopic structures. Trace the droplet edge.

The contact angle can then be calculated when the surface tension of the liquid and the perimeter of the sample are known. You don t have to install the app on a smart phone this online tool just works in the browser. The contact angle measurement with the force tensiometer is based on so called wilhelmy plate method. The dat dynamic absorption tester offers a range of integrated instruments for research as well as quality control.

The contact angle is the angle at the point where this baseline meets the droplet edge. Placing two pushpins will show the degrees of that angle. You can measure the angle of any actual object directly on your screen. The software controlled electrically driven optic alignment enables the oca 200 to adjust the observation angle and to focus automatically.

You can t calculate the contact angle without knowing where the droplet edge meets the baseline. If you want to move the protractor drag the midpoint of it. Measurement and interpretation of contact angles soft matter 2 2006 12.
