In the biopharmaceutical industry, where even microscopic contaminants can compromise drug safety and efficacy, the choice of fluid transfer tubing is critical. Biocompatible silicone tubes have emerged as the gold standard for sterile fluid handling, offering unparalleled purity, reliability, and regulatory compliance. As a leading manufacturer with over 40 years of expertise, Jinan Chensheng Medical Technology Co., Ltd. delivers premium biopharmaceutical-grade silicone tubing engineered to meet the most stringent industry demands.

Biocompatible Silicone Tubes: Ensuring Sterility in Biopharmaceutical Fluid Transfer

The Critical Role of Biocompatibility in Biopharmaceutical Manufacturing


Biopharmaceutical processes—from cell culture to drug formulation—require materials that interact safely with sensitive biological fluids and active pharmaceutical ingredients (APIs). Unlike conventional elastomers, medical-grade biocompatible silicone undergoes rigorous testing to ensure it meets global standards:


  • USP Class VI Certification: Validates non-toxicity and biocompatibility through in vivo and in vitro tests, including systemic toxicity and intracutaneous reactivity.

  • ISO 10993 Compliance: Ensures compatibility with human tissues and fluids, with specific testing for cytotoxicity, sensitization, and irritation.

  • Low Extractables Profile: Platinum-cured silicone minimizes leachables, preventing contamination of APIs during long-term storage or repeated use.


For biopharmaceutical manufacturers, these certifications are not just regulatory checkboxes—they are essential for maintaining product integrity and patient safety.


Key Features of Jinan Chensheng’s Biocompatible Silicone Tubes


Our Biopharmaceutical Grade Platinum-Custom Sterile Tubing is engineered to address the unique challenges of sterile fluid transfer. Here’s how it stands out:


1. Ultra-Pure Platinum-Cured Silicone


Unlike peroxide-cured alternatives, our tubing uses a platinum-curing process that eliminates residual byproducts, ensuring:


  • Animal-origin-free formulation: Eliminates the risk of zoonotic contamination, critical for cell-based therapies and vaccines.

  • Consistent material purity: Batch-to-batch uniformity with strict raw material sourcing from ISO 13485-certified suppliers.

  • Smooth inner surface: Ra ≤ 0.8μm finish reduces protein adsorption and particle retention, minimizing the risk of biofilm formation.


2. Sterilization Versatility


Our silicone tubes withstand multiple sterilization cycles without degradation, supporting flexible process design:


  • Autoclaving: Stable at 121°C (250°F) for 30 minutes, compatible with steam sterilization protocols.

  • Gamma Irradiation: Resistant to doses up to 50 kGy, ideal for pre-sterilized single-use systems.

  • Ethylene Oxide (EtO): Compatible with low-temperature EtO sterilization, preserving integrity for heat-sensitive applications.


3. Customizable Design for Diverse Applications


We offer tailored solutions to match specific process requirements, with a wide range of dimensions and configurations:
