Contact angle – surface free energy – surface tension - roughness:
the DSA30 offers numerous possibilities at a competitive price. The
modular system provides a wide range of high-performance solutions
for studying the surfaces of solids. The contact angle measuring instru‑
ment is ideal for QA material testing of medium sized samples at stand‑
ard measuring throughputs. A large selection of basic components and
accessories offers a solution for almost any measuring problem.
