PEEK tubing (short for Polyether Ether Ketone tubing) is widely used in HPLC (High-Performance Liquid Chromatography) systems because of its excellent chemical resistance, mechanical strength, and biocompatibility.
Main Uses of PEEK Tubing in HPLC
Solvent and sample transfer lines
Used to connect various modules (pump, injector, column, detector) in the HPLC system.
Column inlet and outlet connections
Ensures a leak-free connection between the column and other system components.
Flow path for corrosive or bioinert applications
Ideal for analyses where stainless steel might react with analytes (e.g., proteins, biomolecules, halides, acids).
Micro- and capillary-scale HPLC systems
PEEK tubing is flexible and available in very small internal diameters, perfect for microbore or nano-HPLC setups.
Portable or low-pressure HPLC systems
PEEK’s flexibility and easy handling make it suitable for compact or mobile chromatographic instruments.
