Overview
Challenging biopharmaceutical processes demand superior solutions — including peristaltic pump tubing that provides greater reliability and security against rupture. Conventional extruded silicone pump tubing may balloon or rupture at high pressure. GORE STA-PURE Pump Tubing, Series PCS employs a unique, patented composite structure that overcomes this limitation. Even at pressures up to 100 psig, Series PCS tubing delivers consistent flow rates. Series PCS offers:

Product Information
Unlike conventional tubing, Series PCS is manufactured with a patented composite of platinum-cured silicone rubber, reinforced with expanded polytetrafluoroethylene (ePTFE) for added strength and resilience. Shown: Cross-section of tube wall in detail.
Materials of Construction
Patented composite of thermoplastic material (expanded polytetrafluoroethylene) and elastomeric material (platinum-cured silicone)
Fluid Contact Surface
Platinum-cured silicone
Performance Testing
To simulate challenging real world applications, Gore tested Series PCS tubing for durability in peristaltic pumps under rigorous conditions, up to 100 psig, following multiple cleaning and sterilization cycles. Testing was performed over a wide range of discharge pressures.

a Continuous pumping of room temperature deionized water in Watson-Marlow 500 Series peristaltic pumps, with pump head speed of 220 rpm (two rollers). Samples selected represent the worst-case configuration of pump and tube size based on mechanical stresses imposed by the pump on the tube.
b Tube size = 9.5 mm (ID) x 2.4 mm (WT). When testing was terminated at 2,160 hours, all 6 samples were performing without failure. Failure is defined as rupture, leakage, sustained flow reduction of 25 percent or more, or inability to sustain operating pressure. Tubing was subjected to conditions similar to 5 CIP/SIP cycles (3 cycles before testing and 2 cycles during testing).
c Tube size = 3.2 mm (ID) x 2.4 mm (WT). Six tubing samples were tested until failure as defined in (b) above. The operating life until failure is presented as the average and standard deviation for all samples. The minimum observed value was 52 hours. Before testing, tubing was subjected to conditions similar to 1 CIP/SIP cycle.

Manufacturing Environment and Quality
Series PCS is manufactured and packaged in an ISO 14644-1 Class 7 cleanroom in a manner that adheres to relevant current Good Manufacturing Practices (cGMP) as defined in the Gore PharmBIO Products’ quality system which is certified to ISO 13485 and ISO 15378. Every Series PCS product is visually inspected for contamination and for defects in materials and workmanship. The inner diameter, wall thickness, and length of the tubing are measured for each manufacturing lot and checked to ensure conformance to specifications.
Storage and Shelf Life
The expiration date is four years from the date of manufacture based on an accelerated aging study. The product should be stored in its original packaging at room temperature.
Sterilization
Series PCS has been validated to operate after steam-in-place/clean-in-place (SIP/CIP) and autoclave sterilization. Irradiation sterilization methods such as gamma or electron beam should never be used because they may damage or degrade the mechanical properties of the product.

Product Comparison
GORE STA-PURE Pump Tubing, Series PCS Signifcantly Outperforms Silicone
Pharmaceutical or biotechnology manufacturers may be reluctant to use peristaltic pumps, due to pressure or durability limitations of conventional silicone pump tubing.
Series PCS provides an innovative solution to these performance limitations. A comparison with silicone tubing shows how greatly Series PCS has advanced tubing performance.
