Bioprocess tubing

Bioprocess tubing is the extruded silicone or thermoplastic-elastomer (TPE) hose that carries process fluids — cell culture media, buffers, bulk drug substance — between vessels, filters and other equipment in a biopharmaceutical manufacturing line. The category is a raw-material/component consumable, distinct from the fully integrated single-use assemblies (pre-sterilized flow paths combining tubing, connectors and bags into a validated kit, already a separate vendor category in this catalog) that get built from it: a tubing extruder sells the hose itself, while a systems integrator buys tubing as one input among several to build a complete pre-sterilized assembly. The category splits between platinum-cured silicone tubing, the traditional material offering flexibility and steam-sterilization compatibility, and newer high-purity TPE formulations marketed as a lower-extractables, more consistent-wall-thickness alternative. A further sub-category, braided or reinforced tubing, addresses higher-pressure pump and transfer applications where unreinforced tubing would collapse or burst.

The key directions of bioprocess tubing are:

1. Platinum-cured silicone tubing: the traditional bioprocess tubing material, offering flexibility, steam-sterilization compatibility and a long track record in pump and transfer applications.
2. High-purity TPE tubing: thermoplastic-elastomer tubing formulations marketed as an alternative to silicone with lower extractables and more consistent wall thickness for critical fluid-transfer applications.
3. Braided/reinforced bioprocess hose: tubing reinforced with a braided layer for higher-pressure pump and transfer applications where unreinforced tubing would be unsuitable.
4. Cleanroom-manufactured tubing for single-use assembly integration: tubing extruded and packaged under cleanroom conditions specifically for downstream integration into pre-sterilized single-use assemblies by systems integrators.

Cross-cutting technologies of the sector:

• Platinum-cured silicone tubing: the traditional flexible, steam-sterilizable bioprocess tubing material.
• High-purity TPE tubing: thermoplastic-elastomer tubing marketed for lower extractables and more consistent wall thickness than silicone.
• Braided/reinforced bioprocess hose: tubing reinforced for higher-pressure pump and transfer applications.

The stack splits into the two dominant tubing materials (silicone and TPE) plus a reinforcement layer that addresses higher-pressure applications neither base material alone can handle unaided.

1. Platinum-Cured Silicone Tubing:
   • The traditional bioprocess tubing material, valued for flexibility and steam-sterilization compatibility, produced by all four vendors in some form (AdvantaSil, PharmaFocus, SILMOTION).
   • Raumedic’s SILMOTION and AdvantaPure’s AdvantaSil both continue active product development within this established material category rather than treating it as a mature, unchanging product line.
2. High-Purity TPE Tubing:
   • Marketed as a lower-extractables, more dimensionally consistent alternative to silicone, produced by AdvantaPure (AdvantaFlex/EcoFlex), Saint-Gobain (PharmaPure) and Raumedic (THERMMOTION).
   • Three of the four vendors in this category offer both silicone and TPE lines rather than specializing in one material exclusively, reflecting that end users typically choose material by application rather than by vendor.
3. Braided/Reinforced Bioprocess Hose:
   • Raumedic’s BRAIDMOTION line addresses higher-pressure pump and transfer applications where unreinforced silicone or TPE tubing would be unsuitable, a distinct engineering solution from simply thickening the tubing wall.
   • This sub-category is the least commoditized of the three, with reinforcement construction representing genuine engineering differentiation beyond base material chemistry.
