The general process of aseptic filling for pharmaceuticals usually includes bottle washing, drying, filling, stoppering, (freeze-drying), capping, visual inspection, release testing and other processes. It is a complex continuous production process and the final link in the entire GMP production of biopharmaceuticals. It needs to be strictly combined with the GMP guidelines requirements of China, the United States and the European Union. Tofflon has rich experience in the design and development of aseptic filling machines and can provide feasible, flexible and adaptable solutions for clinical trials, pilot-scale production and commercialization. It is applicable to various packaging materials, including vials, cartridges, pre-filled syringes, ampoules, blow-fill-seal (BFS) containers, inhalants and other dosage forms. Meanwhile, it has participated in the revision of the 2022 version of China's GMP sub-volumes of "Aseptic Preparations" and "Building Facilities and Equipment", as well as the revision of the PIC/S standards for aseptic pharmaceuticals.
