LAUDA Surface Analyzer LSA 100

Thanks to the numerous precise adjusting axes and their wide ranges as well as available expansion functionalities / modules, which are of great importance for challenging applications, the LSA 100 is one of the most versatile and flexible devices on the market. 

The extremely versatile measuring software Surface.Meter is included as a standard as well as the software module for the determination of surface free energy.

Representing the mid-size version of the LSA family, the LSA 100 is even more expandable and customizable with a wide range of dosing systems, sample stages and other accessories.


Special Features:

  • Wide range of drop calculation methods for the contact angle, also including the unique TrueDrop method
  • Powerful fully automatic surface tension measurement
  • Full support of CMC measurements, surface rheology and drop volume tensiometry
  • Up to two different dosing systems integrated (optional non-contact dosing systems, Duo drop dosing picolitre dosing and other modules.
  • Analysis of hydrophobic properties with tilting stage, retention force balance and drop adhesion force measurements
