Industry Trends: Why Polypropylene Falcon Tubes Dominate

Global demand is projected to reach $1.8 billion by 2027 (Laboratory Equipment Magazine), driven by biopharma and diagnostics industries.
Shift to high-clarity polypropylene for improved sample visibility and chemical compatibility. Rigorous resin lot testing is often required.
Expansion in automation readiness: Tubes now routinely support robot pipetting, barcode integration, and are batch-certified for use in validated workflows.
Growing preference for certified testing: Labs demand ISO/CE/FDA certificates for full traceability and safety compliance.

Manufacturing Process of Polypropylene Falcon Tubes

Material: 100% Virgin Polypropylene Resin (biomedical/FDA grade)
Process: High-precision injection molding, automated de-flashing, and robotic capping

Case study: A major Southeast Asian pharma QA lab required polypropylene falcon tubes with oversized barcoding for automated track-and-trace logistics. Working with our engineering team, they co-developed a tube with a printing window, 10% thicker wall for increased drop resistance, dual cap color for error reduction, fully validated to GLP (Good Laboratory Practice) standards. Annual cost savings approached 18% vs global brand alternatives.
