In the late '70s our company recognized that drawing process samples in open containers invited contamination and inaccuracy, and also posed serious health and environmental risks.

Our response: the Dopak ® sampling system, which quickly became the international standard for performance and quality in cost-effective closed-loop and closed vent sampling systems.

We are experts in sampling standards worldwide. In 1981 we established Dopak ® Inc. in the United States to give our many North American customers local access to our sampling system expertise. In 2001 we moved our office from New Jersey to Houston Texas.

When you discover what Dopak ® offers we're confident you'll make Dopak ® your preferred source for sampling systems.
