DST-60 (Surface Tension Analyzer)

Overview

The information of surface or the interfacial tension is critically important in applications such as detergency and emulsification and is also important for many biological processes.  Especially, the Du NÕuy Ring method and the Wihelmy Plate method are commonly used for measuring surface / interfacial tensions.

The DST A series are precise tension meters (with Digital LCD display) for the measurement of surface (Liquid – Vapour) & interfacial tensions (Liquid – Liquid) using both the Du NÕuy ring and the Wihelmy plate.

The sample stage can be automatically operated so that the errors from the manual operation can be significantly minimized and the accuracy can be maximized.  The surface and interfacial tension results can be obtained quickly with no additional calculations and the measured results and data can be shown easily on the LCD display and printed out.

The DST M series is designed for Educational, Quality Control and other multiple user applications.  By simply operating the sample stage manually, you can get the surface / interfacial tension results quickly with no additional calculations.
