Research-Based Automatic Contact Angle Measuring Instrument Lr-Sdc-200s

Product Description

Research-based Automatic Contact Angle Measuring Instrument  LR-SDC-200S
1, Preface
Contact Angle refers to the tangent of gas-liquid interface made at the intersection of gas, liquid and solid. This tangent is in the Angle theta between the liquid side and the solid-liquid boundary. Contact Angle measurement is the main method of surface performance detection nowadays.
LR-SDC - 200S research-based contact Angle measurement instrument is to use the principle of optical imaging device adopts the image contour analysis method can measure the surface contact Angle, wettability, interfacial tension of table, forward backward Angle, surface energy, such as performance, equipment using automatic liquid device, high cost performance, strong expansibility, comprehensive functions, and can meet the demand of conventional measurement, has been widely used in many colleges and universities institutes and enterprises.

2. Instrument Application Field
S Contact Angle measurement instrument is widely used in various fields, such as mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coating ink, electronic circuit, textile fiber, medical biology and other fields, contact Angle measurement has become an important instrument to evaluate the surface performance.
(select special accessories for some test functions)
1. The wetting behavior of the liquid on the solid surface, such as spreading, penetration and absorption, is measured by the static contact Angle with the droplet method;
2. Measure the forward Angle, backward Angle, contact Angle lag, rolling Angle and dynamic contact Angle of the material on the solid surface;
3. Continuous real-time study of absorption materials, process record, and analysis of contact Angle curve with time;
4. Contact Angle measurement of various special materials, such as powder, curved surface, super hydrophobic/super hydrophilic samples;
5. Test the contact Angle of the material immersed in the liquid by the adhesive drop method;
6. Measuring interfacial tension of various liquid surfaces and their polarity and dispersion components by hanging drop method;
7. Calculate the Surface free energy and its polar dispersion component;
8. Analysis of the liquid on the solid surface adhesion (Adhersion), assessment of solid surface uniformity, cleanliness, etc.
