How to Choose the Right Bioprocess Tubing for Single-Use Systems

Introduction

Tubing plays a critical role in single-use bioprocessing. As part of the fluid path, the right tubing solution can support reliable fluid transfer, pumping operations and the handling of sensitive process fluids.

However, different applications require different materials and tubing constructions. Fluid compatibility, pressure, pumping conditions and sterilization requirements should all be considered when selecting bioprocess tubing.

Choosing Tubing Based on the Application

The first step is understanding the process. Tubing used for media and buffer transfer may have different requirements from tubing operating in a peristaltic pump or under higher pressure.

For high-purity fluid transfer, platinum-cured silicone tubing such as VENABIO® Flow Multipurpose provides the flexibility required in many biopharmaceutical processes and single-use assemblies.

In peristaltic pumping applications, repeated compression places additional mechanical stress on the tubing. VENABIO® Flow Pumpgrade is specifically designed for pumping operations where consistent performance is essential.

Different Materials for Different Process Requirements

Material selection is another key factor in single-use system design.

VENABIO® Flex, a TPE tubing solution, is suitable for flexible integration into disposable fluid paths and single-use assemblies.

For applications with higher mechanical or pressure requirements, reinforced solutions such as VENABIO® Technosil provide additional structural support through textile reinforcement.

When chemical compatibility is a critical factor, fluoropolymer solutions such as VENABIO® PTFE and VENABIO® FEP can be considered for specific process fluids and operating conditions.

Key Questions Before Selecting Bioprocess Tubing

Before choosing a tubing solution, consider:

• What fluid will be transferred?
• Will the tubing be used in a peristaltic pump?
• What pressure and temperature conditions are expected?
• Which sterilization method will be used?
• Is reinforced tubing required?
• Will the tubing be integrated into a complete single-use assembly?

These factors help identify the tubing material and construction best suited to the process.

Conclusion

There is no single tubing solution for every bioprocess application.

Silicone, TPE, reinforced and fluoropolymer tubing each respond to different process requirements. Understanding the fluid, pumping conditions, pressure and system configuration is essential when selecting components for a reliable single-use system.
