Overview

The LB membrane analyzer (membrane balance) DCAT 25 is a multifunctional surface tensiometer developed and produced by the German company Dataphysics. Due to its multiple powerful functions, it is commonly referred to as a surface tensiometer (dynamic contact angle meter), adhesion measuring instrument, or Langmuir Blodgett (LB) membrane analyzer. It is a model in the DCAT series, equipped with a TP50 touch panel, which has the characteristics of high precision, powerful functions, wide application, and easy operation.
