SURFTENS‐Basic

Product catalog summary

Overview
SURFTENS-Basic is a fundamental equipment designed for measuring contact angle, surface free energy (SFE), and surface tension. It is equipped with a mechanical setup, measuring optics, and a software module for precise analysis.

Technical Specifications

Mechanical Setup: Includes a base plate (380x260x30mm), a holder for the dosing system, and a lens holder with a fixed viewing angle of 2°.
Measuring Optics: Features a zoom lens with a 6.5x zoom factor, magnification range from 0.35x to 2.25x, and a working distance of about 100mm.
Camera: B/W USB 2.0 camera with 1.3 Megapixel resolution, capable of up to 25 fps at full resolution.
LED Light Source: Includes a power supply and brightness controller.
Specimen Table: Size of 100x200mm with 40mm vertical travel and 70mm x-direction and 30mm y-direction travel.
Manual Dosing Unit: Smallest drop volume of 0.2µl with a dosing resolution of 0.1µl.

Measurement Capabilities

Contact Angle Measurement: Resolution of 0.01° and reproducibility of +/-0.1°.
Surface Free Energy (SFE): Calculated using a double dosing unit with test liquids like water and diiodmethane.
Surface Tension: Measured using the pendant drop method with the SURFTENS PD software module.

Software Features
The SURFTENS image processing software allows for accurate drop analysis, video recording, image storage, and measurement protocol creation. It supports video playback and analysis, applying all measuring functions to videos and individual frames.

Applications
SURFTENS-Basic is used for characterizing cleaning and coating processes and studying surface wettability. It supports static contact angle measurement, advancing and receding angles, and SFE calculation from up to five test liquids.
