> All connectors are made of PEEK material with excellent inertness and biocompatibility, corrosion resistance, high purity, low dissolution and high strength.

> The pipe head is flanged, suitable for low-pressure sealing, and the pipe will not be twisted when tightened.

> Provide various professional customization services, including flanging or hole expansion customization of capillaries with different materials, different inner holes and different lengths.

> Customized services including heat shrinkable number tubes, snap-on labels, model labels, etc. of various specifications.

> There are three materials for the compression ring to choose from, and the connector threads are 1/4-28 and M6.

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.
