Contact angle measuring instrument SURFTENS-universal

laboratorymanual

SURFTENS-universal is a measuring instrument for contact angle, SFE and surface tension. SURFTENS universal covers a wide range of applications in all industry fields, is suitable for specimen up to 50mm thickness and economically priced by manual operation. It can be equipped with motorized pump and other additional features. The modification of the wetting ability of technical surfaces by special surface treatments becomes more and more common in industry and research. For process characterization, adjustment of technological parameters and production control it is therefore absolutely necessary, to measure the surface free energy objectively and accurately before and after the modification process. For this purpose a robust and easy to use contact angle measuring instrument is needed. SURFTENS universal was developed to meet the needs in industry and research. The operation is simple and for everybody possible after a short training. The SURFTENS universal standard equipment has 1 manual dosing unit. The image processing software measures fully automatic the contact angle with highest accuracy. The software includes a module for calculation of surface free energy (SFE) using the contact angles of up to 5 measuring liquids. The manual dosing unit is excellent operateable and allows the effective and fast measurement of wettability of the surface, for instance the test of surface cleaning or pre-treatment. Using a special software function, a reproducibility of the drop volume of 0,1µl can be easily achieved.
