Materials in Bioprocessing: Building Blocks of Quality & Innovation

Materials in Bioprocessing

In the dynamic realm of bioprocessing, the choice of materials plays a pivotal role in shaping the efficiency, safety, and sustainability of the biopharmaceutical industry. From stainless steel to plastics, each material used in bioprocessing serves a specific purpose. Each contributes to the advancement of healthcare and the production of life-saving therapies. In this article, we’ll explore the wide array of materials used in bioprocessing and why they are instrumental in driving progress in the field.

Stainless Steel: The Traditional Workhorse

Stainless steel has long been the backbone of bioprocessing equipment. Its durability, resistance to corrosion, and longevity make it a reliable choice for critical components like tanks, bioreactors, and piping. Stainless steel systems are known for their ability to withstand rigorous cleaning and sterilization processes, ensuring product purity and regulatory compliance.

Plastics: Flexibility and Adaptability

The emergence of plastics in bioprocessing has revolutionized the industry. Materials like polyethylene, polypropylene, and polyvinyl chloride (PVC) offer flexibility, adaptability, and cost-effectiveness. They are commonly used for single-use systems, disposable bags, and tubing components.

Polyethylene (PE): PE is renowned for its flexibility and chemical resistance. It is often used for disposable bags and containers in single-use systems.

Polypropylene (PP): PP is valued for its versatility and robustness. It is suitable for various bioprocessing applications, including filtration and chromatography.

Polyvinyl Chloride (PVC): PVC is known for its transparency, making it ideal for monitoring fluid flow in tubing. It is widely used for tubing in bioprocessing.

Thermoplastic Elastomers (TPE): Balancing Flexibility and Biocompatibility

TPE materials, such as silicone and thermoplastic elastomer (TPE), offer a unique combination of flexibility and biocompatibility. They are favored choices for single-use systems, tubing, connectors, and seals.

Silicone: Silicone is recognized for its high biocompatibility, making it suitable for applications involving sensitive biologics and pharmaceuticals. Its resilience and temperature tolerance are also significant advantages.

Thermoplastic Elastomer (TPE): TPE materials, like TPE tubing, are known for their flexibility, cost-effectiveness, and reduced risk of contamination. They are ideal for single-use systems and adaptable to complex bioprocessing setups.

Glass: Clarity and Purity

Glass is revered for its transparency, inertness, and the ability to maintain product purity. It is commonly used for bioreactor vessels, storage containers, and lab ware. The clarity of glass allows for real-time observation of processes, a crucial aspect of research and development.

Future Materials: Driving Innovation

As the biopharmaceutical industry continues to evolve, so too will the materials used in bioprocessing. Emerging materials such as advanced polymers, nanomaterials, and biodegradable plastics are being explored for their potential to enhance sustainability, reduce environmental impact, and improve product quality.


Materials are the unsung heroes of bioprocessing, each chosen for its unique properties and advantages. From stainless steel’s durability to plastics’ adaptability and TPE’s flexibility, these materials are the building blocks of innovation and progress in the biopharmaceutical industry. As we move forward, it’s essential to stay attuned to emerging materials that can drive even greater advancements in bioprocessing, ultimately leading to improved healthcare and a more sustainable future.
