PEEK Tubing

Target Analysis distributes high-pressure tubing with bioinert PEEK, formally known as polyetheretherketone. PEEK is a high-performance engineered polymer with mechanical and chemical resistance properties that absorbs high temperatures, making it highly resistant to thermal degradation. PEEK tubing has one of the highest strength-to-weight ratios of any thermoplastic and the strength required to withstand continuous use at HPLC pressure. Its distinct materials make it inert to most solvents and give it a smooth internal surface that improves the resolution of sample bands. With its introduction into the marketplace, PEEK materials have become a popular replacement for stainless steel tubing for fluidic needs.

PEEK vs. Stainless Steel Tubing

PEEK acts as an excellent alternative for stainless steel tubing in high pressure applications and analytical systems. Its mechanical properties allow it to be used in many situations where stainless steel would become too reactive. Unlike stainless steel, PEEK tubing is flexible and can be easily cut into preferred lengths with a razor blade. PEEKs internal surface is much smoother than that of metal tubing, thereby reducing the risk of dilution and remixing of samples.
