Herzog by PAC Celebrates 80 Years of Scientific Excellence

For eight decades, the company founded by Walter Herzog, which is now a part of the PAC family, has been successfully providing high-accuracy and high-reliability analytic instruments to the world’s industrial scientists. The name “Herzog” is respected the world over, and for good reason; the company’s continuing strength since its founding is its commitment to excellence and innovation.

Walter Herzog founded Walter Herzog GmbH in Berlin, Germany in 1931 He then moved to Lauda, Germany with four employees in 1960. Herzog by PAC is a long-established, comprehensive line of laboratory instruments for testing atmospheric and vacuum distillation, flash point, vapour pressure, bitumen properties, cold flow properties, viscosity and other physical properties of materials. Distillation and flash point analysis is provided by systems, including the OptiDist and the HDV 632; viscosity and Bitumen testing by systems, such as the HVM 472 and the HRB 754 Ring & Ball; and fuel classification by systems, such as the CID 510 Derived Cetane Number.

Herzog is an active member in standards organisations and leads in standard development to guarantee that the methods meet customer requirements of precision and ease of use.

Pioneer and Innovator
Walter Herzog and his engineers pioneered efforts to automate traditional manual methods of testing in order to save manpower and eliminate user errors. Herzog also took the lead in efforts to develop and standardise new, alternative lab methods where the hallmarks were low sample volume requirements, achieving faster results, higher precision in analysis, and greater ease of use by operators with lower general skill levels.

From the start, Herzog has been an innovator in physical distillation. Herzog introduced its first automated ASTM D86 / ISO 3405 distillation system to the market in 1957. Today, Herzog continues to innovate in synergy with other members of the PAC family with its 5th generation system, the OptiDist®, which combines 50 years of Herzog experience and 30 years of ISL’s to create a unique, state-of-the-art, fully automated distillation analyser. OptiDist® uses several patented technologies, such as Optimizer and bottom meniscus volume measurement, for fully automated distillation control that guarantees highest precision results, and it is ideal for new fuels including ethanol blends and biodiesel blends.
