Choose the Right Peristaltic Tubing to Protect Light-Sensitive Fluids — PharMed® BPT Explained

Light-sensitive fluids can degrade quickly under light. This practical guide explains PharMed® BPT’s light-blocking and CIP compatibility, with actionable selection and validation tips.

Typical light-sensitive fluids

  • Pharmaceuticals: formulations containing photosensitive actives, serum, and vaccines

  • Fine chemicals: photoresins, photoresists, specialty dyes and monomers

  • Lab reagents: fluorescent dyes, photosensitive proteins and probes

Why PharMed® BPT is appropriate

  1. Strong light-blocking properties — reduces light penetration in both visible and UV ranges, protecting photolabile compounds.

  2. Chemical and thermal stability — compatible with many mild acids/bases and some solvents; withstands autoclave cycles and repeated CIP/SIP.

  3. Durability — purpose-built for peristaltic pump wear and tear; longer service life than typical silicones, reducing downtime.

What “withstands repeated CIP” means

CIP (Clean-In-Place) uses circulating cleaning solutions without disassembly. Tubing that tolerates repeated CIP will not crack, deform, or degrade under hot alkaline/acid circulation, preserving internal surface integrity and reducing contamination risk.

Recommended applications

  • Pharmaceutical lines for photosensitive formulations

  • 3D printing resin feed systems

  • Laboratory instruments handling fluorescent or photosensitive reagents

  • Fine chemical dosing where light exposure can trigger unwanted reactions

Conclusion & practical tip

For any light-sensitive or chemically demanding fluid, choose an opaque, validated tubing. Always run a site-specific compatibility and UV-Vis transmission test to confirm the tubing meets your process protection requirements.
