Due to technical barriers and other reasons, the filter market has been monopolized by multinational corporations for a long time. High-end filters are almost always imported from overseas, resulting in high prices for customers. At present, many domestic biopharmaceutical enterprises are suffering from sanctions because of the Sino-American trade war that is still ongoing. Saipu is committed to providing stable and secure filters for our clients to help them gain independence from foreign filters and avoid supply chain issues resulting from the trade war. Our ultimate goal is to end the monopoly of foreign technology in filtration and replace it with our products. In this way we will uniquely contribute to the long-term development of China's pharmaceutical industry.
