Junhua provides ultra-pure, corrosion-resistant PEEK components for analytical/testing industries, including multi-way valves, gem check valves, high-pressure fittings, and chromatographic columns. Made with grades like PEEK5600G (toughness) and PEEK5600GF30 (high pressure resistance), our parts feature low dissolution, high abrasion resistance, and dry ice deburring (no burr blockage). Ideal for HPLC, protein purification, IVD, and environmental monitoring equipment—replacing stainless steel to ensure accurate analytical results. Backed by 100,000-level clean workshops for quality assurance.
