> PEEK has been successfully applied in analytical and testing instruments, such as liquid chromatographs, and has solved many technical problems. PEEK pump heads, peek chromatography columns and plugs, peek switching valve covers, peek vent valves, peek quantitative rings, peek rotor seals, PEEK filters and other high-performance plastic parts made of PEEK and its modified composite materials can replace parts made of traditional materials such as copper alloys, stainless steel, and ordinary engineering plastics, meeting the requirements of high temperature resistance, corrosion resistance

Strict technical requirements such as self-lubrication, high strength, high precision, and dimensional stability can reduce the cost of use and help improve the accuracy of equipment testing.

Junhua  focuses on the application research and development and production of high-performance polymer plates, rods, tubes, sheets and other profile finished parts such as PEEK (polyetheretherketone) and PI (polyimide).

The high-purity, corrosion-resistant, and low-dissolution PEEK high-performance plastic parts developed by our company have been widely used in analytical chromatography instruments, preparative and semi-preparative chromatography instruments, protein purification equipment, IVD instruments, sample pretreatment equipment, pharmaceutical and environmental monitoring equipment and other related equipment.

With 18 years of experience in the production and development of PEEK parts, the company has cooperated with customers in the analytical biochemical instrument industry to develop nearly 500 types of PEEK high-performance plastic parts molding molds, and has sufficient inventory of various parts.

Typical products include: PEEK connectors, PEEK two-way, three-way and four-way connectors, PEEK pump heads, PEEK plugs, PEEK Luer connectors, PEEK chromatographic columns, PEEK quantitative rings, PEEK filter columns, PEEK microwave digestion tanks, PEEK capillaries, PEEK injection needles, PEEK sampling needles, PEEK nitrogen blow needles, solvent filter heads, sinkers, fluoroplastic flanged tubes, etc.
