PharmaPure® and PharMed® BPT: Proven Leaders in Low-Spallation Reliability
In complex fluid systems, reliability is achieved through attention to detail. Tubing may not determine overall performance on its own, but when it performs consistently, everything else runs more predictably.
That consistency depends on controlling a small but measurable effect: spallation, the microscopic release of particles that occurs when tubing is compressed and released inside a peristaltic pump. Over time, these particles can collect in filters, alter flow resistance, or interfere with sensors. Managing spallation is one of the most effective ways to maintain system stability and extend operating life.
Among all peristaltic pump tubing tested, PharmaPure® and PharMed® BPT tubing have consistently demonstrated the lowest spallation levels and most stable performance in their respective categories. Their ability to minimize particle generation while maintaining long pump life has made them the reference standard for reliable, clean flow across medical, analytical, and life-science applications.
Why Spallation Matters in Tubing Selection
Spallation is not a defect. It is a result of repeated mechanical motion. Each cycle of a peristaltic pump introduces small amounts of surface stress. Over time, those stresses can lead to microscopic wear and particle release. In sensitive systems, even minor increases in particulate load can shorten filter life, shift pressure profiles, or affect measurement accuracy.
Controlling spallation has a direct impact on total system performance. Fewer particles mean longer maintenance intervals, more stable baselines, and more predictable service schedules. Low-spallation tubing supports both operational efficiency and confidence in system reliability.
Tested and Proven: PharmaPure & PharMed BPT Tubing Performance
Saint-Gobain has studied spallation for decades, refining test methods to reflect real operating conditions more accurately than standard laboratory procedures. In comparative evaluations modeled after ISO 19727:2017, PharmaPure and PharMed BPT tubing outperformed all competitive peristaltic pump tubings tested.
- PharmaPure Tubing: Achieved the lowest measured particle counts overall, maintaining exceptional cleanliness and flow stability during extended operation.
- PharMed BPT Tubing: Combined long pump life with consistently low spallation and high mechanical endurance, confirming its reputation for dependable, continuous use.
Both tubings deliver performance that competitive options have yet to match.
System-Level Benefits of Low-Spallation Tubing
Low spallation is not just a material property. It translates directly into measurable system benefits. Reduced particle generation leads to:
- Longer filter life and fewer replacements
- Improved sensor stability and calibration retention
- Reduced flow variation over time
- Lower frequency of unplanned service events
These advantages allow engineers and operators to design around predictable maintenance cycles, minimize downtime, and extend the useful life of equipment.
Engineering for Durability: How Saint-Gobain Controls Spallation
The performance of PharmaPure and PharMed BPT tubing reflects the experience of Saint-Gobain in controlling both material behavior and process precision. Each tubing is produced with tightly managed extrusion surfaces, optimized wall recovery, and a balance of elasticity and resilience that limits surface fatigue and abrasion, the two leading causes of spallation in peristaltic pump tubing.
The result is lower particle generation and predictable wear characteristics, giving engineers confidence in how systems will perform from the first cycle to the last.
Reliability by Design: Why PharmaPure & PharMed BPT Tubing Stand Out
Spallation may occur on a microscopic scale, but its effects are felt throughout the system. By minimizing it at the source, PharmaPure and PharMed BPT tubing extend the performance of pumps, filters, and sensors while maintaining consistent flow and pressure stability.
Across every controlled test, both tubings have demonstrated lower spallation and more consistent operation than competitive options, confirming their position as the reference standard for peristaltic pump reliability.
Choosing Proven Low-Spallation Tubing for Critical Systems
Reliable fluid handling depends on components that maintain integrity under stress. PharmaPure and PharMed BPT tubing exemplify that standard. Their proven low-spallation performance, long service life, and predictable wear make them the trusted choice for systems that demand stability over time.
For engineers designing medical, analytical, or life-science equipment, these two options remain the benchmark for what dependable peristaltic performance should look like: consistent, repeatable, and validated by results.
