PEEK has been very successfully applied in the analytical and testing instrument industry, solving many technical challenges; PEEK fittings, PEEK chromatography column plugs, PEEK ferrules, PEEK two-way connectors, PEEK three-way connectors, PEEK luer connectors, PEEK digestion vessels, PEEK mixing tees, PEEK tubes, PEEK bulkhead two-way connectors, PEEK panel mount connectors, PEEK high-pressure pump heads, biochip PEEK connectors, PEEK four-way connectors, PEEK valve heads, PEEK rotors, PEEK stators, and other PEEK external thread two-way connectors, among other high-performance plastic parts, can replace components made from traditional materials such as copper alloys, stainless steel, and ordinary engineering plastics. These parts meet the stringent technical requirements of analytical and testing instruments, including high-temperature resistance, corrosion resistance, self-lubrication, high strength, high precision, and dimensional stability, thereby reducing usage costs and enhancing the accuracy of equipment testing.

The main features of PEEK hand-tight fittings in the analytical instrument industry are: corrosion resistance, high-pressure resistance, insulation, high precision, ease of processing, and the ability to mass-produce parts through one-time injection molding, which reduces costs.
