Dopak® has manufactured innovative sampling instruments and equipment manufacturing since 1926. In the late 1970s, the company recognized that drawing process samples in open containers posed contamination and inaccuracy, as well as serious health and environmental risks. In response, Dopak developed closed vent sampling systems, which quickly became the international standard for performance and quality. Dopak systems are designed to meet the most demanding technical sampler and safety specifications.

Beyond Dopak’s reliable and accurate sampling equipment, its highly trained and experienced technical personnel can provide sampling advice, because specialized products require customized, expert support. Dopak operates from Bergschenhoek, Netherlands and Houston, Texas.
