New Upchurch Scientific® PEEK™- Lined
Stainless Steel Tubing
IDEX Health & Science introduces new Upchurch Scientific® PEEK™-Lined Stainless Steel (PLS) Tubing. The metal-free, all-PEEK fluid path withstands pressures to 15,000 psi (1,035 bar), making it the ideal choice for biocompatible UHPLC applications. Coupling the chemical compatibility of PEEK with the strength of stainless steel, other innovative design features of PLS tubing also assures better overall dimensional tolerances (±5-15 µm, depending upon the inner diameter) over traditional PEEK tubing or stainless steel tubing.
