• 1/16", 1/8" and 1.8mm ODs Available
• Biocompatible, Inert and Easily Cut
• Great for High Pressure Applications
PEEK (polyetheretherketone) polymer tubing is biocompatible, chemically inert to most solvents, and can be used to replace stainless steel tubing in most liquid analytical systems. Unlike stainless steel and titanium tubing, PEEK tubing is flexible and can be easily cut to desired lengths. PEEK tubing can be used with stainless steel or polymer fittings.
The benefits of PEEK polymer tubing include a high pressure rating (up to 7,000 psi in most cases) and a high temperature rating (maximum continuous use temperature of 100ºC).
Additionally, PEEK tubing has a very smooth internal surface, which causes less turbulance than similar sized metal tubing.
Turbulence can cause remixing of separated sample bands and dilution of bands by the mobile phase. Of all our polymer tubing materials, PEEK is the least permeable to gas.
• PEEKsil™ tubing is mechanically strong and has ideal characteristics for sealing with polymer fittings. It is comprised of high quality fused silica sheathed by PEEK tubing giving it excellent chemical compatibility. We hold it to very tight manufacturing tolerances delivering reliability. It can be an excellent replacement for stainless steel, PEEK, or standard fused silica.
Los tubos de Teflón (FEP) son químicamente inertes y son adecuados para bajas presiones.
Los tubos de TEFZEL soportan presiones de trabajo superiores al Teflón, pero su uso está limitado a soluciones acuosas.
En ambos casos el material es extrusionado con una muy elevada precisión teniendo tolerancias de .001” para el OD para 1/16 y de .003” para tubos de 1/8”.
• Available in three forms: PFA, High Purity PFA and High Purity “PLUS” PFA
• ODs ranging from 360 µm to 1/4"; IDs ranging from 50 µm to 3/16"
• Offers higher purity and enhanced translucence when compared with other fluoropolymer tubes
Upchurch Scientific® PFA Tubing offers numerous advantages over other fluoropolymer tubing options available today. It comes in three standard “grades” – Standard PFA, High Purity PFA, and High Purity “PLUS” PFA – each discussed below.
