Overview
LongerPump Norprene® Chemical-Resistant Peristaltic Pump Tubing is a high-performance fluid path component engineered for continuous, precise, and contamination-free transfer of aggressive chemical solutions in laboratory, pilot-scale, and industrial process applications. Unlike conventional silicone or PVC tubing, Norprene® tubing features a proprietary thermoplastic elastomer formulation with an ultra-smooth, fluoropolymer-mimetic inner surface—chemically inert and functionally analogous to PTFE in resistance to adsorption and leaching. Its dual-layer architecture integrates a non-plasticized, extractables-free lumen with a reinforced, abrasion-resistant outer jacket, delivering exceptional service life under repeated compression cycles in peristaltic pump systems. This tubing operates on the fundamental principle of positive displacement via occlusion: rollers compress the tube against a curved housing, creating a sealed fluid pocket that advances axially without contact between the pump mechanism and the process fluid—ensuring full isolation, zero cross-contamination, and compliance with stringent purity requirements.
Key Features
- Chemical Inertness: Resists concentrated acids (e.g., HCl, HNO₃, H₂SO₄), caustics (NaOH, KOH), alcohols (methanol, ethanol, isopropanol), ketones (acetone, MEK), chlorinated solvents, and oxidizing agents—validated per ASTM D471 and ISO 1817 immersion testing protocols.
- Non-Adsorptive Surface: Smooth, non-porous inner wall eliminates liquid retention, minimizes sample carryover, and prevents analyte binding—critical for HPLC mobile phase delivery, reagent dispensing, and cell culture media transfer.
- No Plasticizers or Leachables: Compliant with USP Class VI and FDA 21 CFR §177.2600; certified free of phthalates, bisphenol A (BPA), and other extractable compounds—suitable for GLP/GMP environments and regulatory submissions.
- Predictable Fatigue Resistance: Maintains dimensional stability and flow consistency over >500 hours of continuous operation at standard peristaltic speeds (e.g., 60 rpm with YZ1515X head), significantly extending maintenance intervals versus generic elastomeric tubing.
- Dimensional Precision: Tight tolerances on inner diameter (±0.05 mm) and wall thickness ensure repeatable flow rates and accurate volumetric dosing across multiple pump head models.
Sample Compatibility & Compliance
This tubing is validated for use with aqueous, organic, and mixed-phase solutions commonly encountered in analytical chemistry, bioprocessing, environmental monitoring, and pharmaceutical manufacturing. It meets ISO 9001-certified production standards and conforms to key regulatory frameworks including EU Directive 2002/72/EC for food-contact materials and REACH Annex XIV restrictions. While not intended for sterile filtration or high-pressure applications (>3 bar), it supports aseptic transfer when paired with autoclavable pump heads (e.g., YZ35-13) and validated cleaning-in-place (CIP) protocols using 0.5 M NaOH or 70% IPA. Documentation packages include lot-specific certificates of conformance, extractables test reports, and biocompatibility summaries per ISO 10993-5.
Software & Data Management
As a passive fluid path component, Norprene® Chemical tubing does not incorporate embedded electronics or firmware. However, its performance metrics—including flow rate deviation, pressure drop, and service life—are fully integratable into longer-term equipment validation workflows. When used with LongerPump’s programmable controllers (e.g., BT100-2J or WP1000 series), tubing selection parameters (ID, wall thickness, material grade) are stored in pump configuration files to auto-calculate calibrated flow profiles. Audit trails generated during calibration and routine performance verification comply with FDA 21 CFR Part 11 requirements when deployed with validated electronic record systems.
Applications
- HPLC and UHPLC solvent delivery lines where low background and minimal dwell volume are essential
- Automated titration and ion chromatography eluent supply systems
- Continuous feeding of corrosive catalysts or etchants in semiconductor wet benches
- Media and buffer circulation in single-use bioreactors and perfusion culture platforms
- Environmental wastewater sampling systems handling acidic digests or cyanide-containing extracts
- Pharmaceutical cleaning validation—delivery of rinse solutions containing sodium hydroxide or peracetic acid
FAQ
Is Norprene® Chemical tubing suitable for sterilization by autoclaving?
Yes—up to 5 cycles at 121°C, 15 psi, provided the tubing is installed loosely in the pump head and not subjected to mechanical stress during heating/cooling phases.
Can this tubing be used with ozone or hydrogen peroxide vapor (HPV) decontamination systems?
It demonstrates acceptable resistance to HPV at concentrations ≤1000 ppm and exposure durations ≤2 hours; however, prolonged ozone exposure (>100 ppm, >30 min) may accelerate surface oxidation and reduce flex life.
What is the maximum recommended operating pressure for 12.7 mm ID (82#) tubing?
The burst pressure exceeds 4.2 bar at 23°C; however, continuous operation should remain below 2.5 bar to maintain long-term occlusion integrity and flow linearity.
Does LongerPump provide lot-specific extractables data for GMP audits?
Yes—certificates of analysis (CoA) with ICP-MS and GC-MS screening for elemental and organic leachables are available upon request for all production lots shipped to regulated users.
