The Worldwide Standard in Sampling

Dovianus B.V. markets Dopak® sampling systems for liquids and gases. Dopak is the most respected sampling system brand worldwide in petro-chemical and chemical markets. Dopak sampling innovation has roots tracing back to 1926 with instrument and equipment manufacturing. In the late ‘70s, the company recognized that drawing process samples in open containers invited contamination and inaccuracy and also posed serious health and environmental risks. The response: Dopak® closed vent sampling systems, which quickly became the international standard for performance and quality. Dovianus B.V. established Dopak® Inc. in the United States in 1981 to give North American customers local access to our sampling system expertise.
