Sterile technology in apparatus engineering refers to the design and manufacturing of systems, components, and equipment used in hygiene-critical sectors such as the pharmaceutical, food, and chemical industries. The objective is to ensure that all processes are designed in a way that completely prevents microbiological contamination or cross-contamination. This not only includes the selection of suitable materials, but also the design of dead space-free constructions, smooth and easy-to-clean surfaces, and the safe welding of piping systems. Compliance with relevant standards and regulations is just as crucial as having many years of hands-on experience in sterile system implementation.
