Our metal free treatment of stainless steel is excellent for any compound that will interact with stainless steel

PEEK is a highly inert material which has been used in HPLC applications for years. However, PEEK has some limitations:

    • Mechanical strength: PEEK begins to flex at 3000 to 5000 PSI, making it unsuitable for UHPLC and other applications where high pressure is required.
    • Work-ability: Machining of PEEK doesn’t produce sufficiently consistent IDs, which disrupts flows and can shift retention times.
    • Environmental: PEEK has temperature limitations and solvent related swelling issues which limit solvent and temperature options for the user.

Our metal free stainless steel offers a robust and inert alternative to PEEK.
