Technical-physical laboratory

Flawless test and measurement procedures with certified quality according to DIN ISO 9001:2015.

Testing, measurement and quality control for elastomers and gaskets

State-of-the-art measuring and testing procedures form the basis for reliable quality assurance and the flawless product quality of our gaskets.

With certified quality according to DIN ISO 9001:2015, we carry out all tests in our in-house laboratory. As a result, our entire manufacturing process benefits from flexibility and speed. Supplemented by the competence, routine and many years of experience of our laboratory team, the gaskets from Kroll & Ziller stand for the highest quality ”Made In Germany.”
