Peristaltic pump tubing GORE® STA-PURE PFL

for medical device manufacturingstainless steelPTFE

Overview
GORE® STA-PURE PFL is a perfluoroelastomer tubing reinforced with expanded PTFE (ePTFE) designed for pharmaceutical and biotech fluid transfer. The ePTFE/platinum-cured perfluoroelastomer composite delivers exceptional chemical resistance, very low extractables and extended service life. It resists aggressive solvents such as MEK, toluene and acetone, is free from plasticisers and acid acceptors, and meets USP Class VI for pharmaceutical applications.

Features and benefits

• Highly resistant to aggressive chemicals, including organic solvents (MEK, toluene, acetone)
• Over 50× longer life than conventional fluoroelastomers
• Stable flow rate and very low spallation
• Pressure rating up to 4 bar (model dependent)
• Compatible with CIP and SIP; autoclave sterilisation possible
• Operating temperature: -20 °C to 80 °C
• Available in 20 bore sizes (1.6–17 mm), multiple wall thicknesses and element lengths (305–610 mm)
• Free from plasticisers and acid acceptors; very low extractables (USP Class VI)
