Dopak® develops, produces and markets sampling systems for liquids, liquefied gases and gases: most respected in the internat ... ional markets in (petro) chemical industries. In 1926 Dopak® began as a instrumentation and equipment manufacturing. Due to the spectacular demand for environmentally safe sampling systems in the late ‘70s, Dopak® decided to focus on the development, production and marketing of Dopak® sampling systems. Quickly Dopak® became the international standard for performance and quality in closed loop and closed vent sampling systems. Dopak® is the expert 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. The Dopak® samplers concept is widely used and accepted among the chemical and petrochemical industry. Sampling directly from the process includes the risk of exposure to the operator as well as contamination and pollution to the environment. Dopak solves the problem of taking samples of toxic, dangerous and volatile substances and guarantees representative samples. With Dopak® closed vent samplers for liquids, gas, liquefied gas and solids, the operator is better shielded from contact with the product, local spillage can be avoided and representative samples guaranteed. Dopak® sampling systems: safer for the operator, safer for the environment and safer for the sample. read more
