Reactors in the pharmaceutical industry are specialized vessels designed to facilitate chemical reactions and bioprocesses under controlled conditions. They are essential for the production of active pharmaceutical ingredients (APIs), biopharmaceuticals, and other complex molecules. Glass reactors are commonly used for drug synthesis, providing a controlled environment to optimize reaction conditions, yields, and product purity. High-pressure reactors, on the other hand, are employed to accelerate multi-step reactions, enabling precise kinetic control and reducing drug development timelines. Reactors are versatile, with applications ranging from cell culture and fermentation to distillation, crystallization, and extraction. Their design and material composition vary depending on the specific process requirements, ensuring efficiency, safety, and scalability in pharmaceutical manufacturing.
