Systematic hygiene since 1912
Chemische Fabrik Dr. Weigert GmbH & Co. KG develops, produces and distributes cleaning and disinfection agents as well as central and decentralised dosing and control systems (dosing technology and plant engineering) for automated cleaning and disinfection at its headquarters in Hamburg. The product range includes process chemicals under the neodisher®, neomoscan® and niroklar® brands as well as dosing technology under the weigomatic® and neomatik® brands, from compact dosing units and cartridge systems through central dosing systems with data acquisition to mixing devices and programmable cleaning systems. Customer industries include medical and laboratory technology (CSSD, endoscopy), commercial and communal catering, and the pharmaceutical, cosmetics, food, beverage and dairy industries. In addition to formulation and production, the company offers its own research and development with a laboratory and test dishwashing machine, microbiological efficacy testing, an accredited water analysis laboratory, as well as application engineering and hygiene concepts. Founded in 1912, the owner-managed family business is represented with subsidiaries in several European countries and an office in the USA, and delivers worldwide.
