How Single-Use Assemblies Are Revolutionizing Biopharmaceutical Manufacturing?

What if you could eliminate the risk of cross-contamination, reduce downtime, and boost operational efficiency, all while maintaining compliance with global regulatory standards? That’s exactly what single-use assemblies offer to modern biopharmaceutical and life sciences industries. These preassembled, presterilized components are redefining how companies approach upstream and downstream processing. Unlike traditional stainless-steel systems that require rigorous cleaning, single-use assemblies are pre-sterilized, disposable components used in drug production, vaccines, and biologics.

But how do they work? What industries benefit the most? And are they truly sustainable? In this blog, we’ll explore how single-use assemblies enhance efficiency and reduce operational costs. Whether you're in biopharma, cell therapy, or food processing, understanding single-use assemblies could revolutionize your workflow. Ready to discover why the future is disposable? Let’s begin! 

What Are Single-Use Assemblies?

Single-use assemblies are pre-sterilized, disposable components designed for use in biopharmaceutical processes, often for fluid transfer, mixing, filtration, or containment. Made from plastics like polyethylene and polypropylene, they replace traditional reusable stainless-steel systems in industries where sterility and efficiency are critical. Single-use assemblies are used once and then discarded, eliminating cleaning validation steps and significantly reducing contamination risks.

Market Stats

The single-use assemblies market size was estimated at USD 12.80 billion in 2024. A CAGR of 16.5% is anticipated for the market over the forecast period, which is expected to reach a valuation of USD 58.83 billion by 2034.

Key Components of Single-Use Assemblies

Typical components include:

• Tubing and Connectors: Made from materials like silicone or TPE, essential for fluid transfer.
• Filter Capsules: For sterilizing or removing particulates and microorganisms.
• Sampling Ports and Sensors: Allow in-process monitoring and quality control.
• Bioprocessing Bags: For mixing, storage, and transfer of liquids.
• Manifolds and Clamps: Enable secure integration of multiple lines and flow paths.

These components are customized based on specific production needs and supplied presterilized, usually via gamma irradiation.

How Do Single-Use Assemblies Work?

Single-use assemblies function as closed systems, minimizing human intervention and contamination risks. Here’s a breakdown of their role in bioprocessing:

• Upstream Processing (Cell Culture): This stage involves growing cells in bioreactors to produce the desired protein or drug substance. This includes cell line selection, media optimization, and fermentation or cell culture. It can be used to simplify the process and reduce contamination risks.

• Downstream Processing (Purification): After the cells have produced the desired product, downstream processing separates and purifies the protein or drug substance from the cell culture. This involves techniques like filtration, centrifugation, chromatography, and other separation methods.

• Final Fill and Finish: Once the product is purified, it's prepared for patient use through processes like filtration, sterile filling, and packaging into vials, disposable syringes, or other dosage forms. These components can be used to minimize the risk of contamination and reduce cleaning time.

Benefits of Single-Use Assemblies

Reduced Risk of Contamination

Single-use assemblies minimize contamination risks in manufacturing by eliminating the need for cleaning and sterilization between production runs. This is because each component is used once and discarded, ensuring a fresh, sterile environment for each batch. This also helps in cross-contamination prevention and microbial contamination from reusable equipment.

Increased Efficiency and Productivity

Single-use assemblies enhance efficiency and productivity in biomanufacturing by reducing downtime, minimizing contamination risks, and enabling faster scale-up and scale-down operations. They eliminate the need for extensive cleaning and sterilization between batches, allowing for faster transitions and improved operational efficiency. Additionally, their flexibility and modularity support continuous improvement and process optimization, leading to greater cost-effectiveness. Furthermore, the reduced downtime and improved efficiency associated with single-use assemblies can lead to lower operational costs.

Flexibility and Scalability

Single-use assemblies offer significant flexibility and scalability in biopharmaceutical manufacturing, enabling rapid adaptation to changing needs and process requirements. These pre-made solutions allow for quick batch conversions, seamless process adaptations, and streamlined scaling of production. By eliminating the need for extensive cleaning and maintenance, single-use systems reduce downtime and accelerate manufacturing times. They are designed with modular components, allowing for easy customization and adaptation to various process needs. They enable rapid prototyping and testing of new production methods in the early stages of drug development, minimizing financial risk.

Emerging Trends in Single-Use Technology

Integration of Sensors and Automation: The trend of integrating IoT sensors and automation into single-use assemblies is growing, offering advancements in bioprocessing solutions by streamlining workflows, enhancing process control, and reducing costs. This integration allows for real-time monitoring and control of critical parameters, leading to improved product quality and consistency.

Rising Emphasis on Sustainable Innovations: The shift toward sustainable single-use assemblies is driven by the need to reduce environmental impact and improve efficiency in various industries, particularly biopharma. This involves using biodegradable materials, reducing waste, and implementing circular economy strategies. Bio-based polymers and plastics are increasingly being used in single-use assemblies, driven by growing concerns about plastic pollution and a push for more sustainable alternatives (e.g., sugarcane-derived polyethylene).

Increased Outsourcing to CDMOs and CMOs: CDMOs and CMOs, providing specialized services for pharmaceutical research and manufacturing, are heavily reliant on single-use systems for their flexibility, speed, and cost-effectiveness. This shift is particularly strong as CDMOs and CMOs handle multiple projects with varying scales and needs, making single-use systems ideal for rapid transitions between different processes and for minimizing cleaning and validation time.

Rise of Biologics and Cell Therapies: The increasing demand for biologics and cell therapies is fueled by the advantages SUAs offer, such as reduced contamination risks, lower capital costs, and increased manufacturing flexibility. The demand for biologics, including monoclonal antibodies, vaccines, and biosimilars, is rising due to advancements in medical science and the increasing prevalence of chronic diseases.

Conclusion

As the need for high-speed, flexible, and sterile manufacturing grows, single-use assemblies will remain a central pillar in the biopharma manufacturing landscape. With their promise of efficiency, sterility, flexibility, and regulatory compliance, these systems have become essential tools in the production of modern therapies. While challenges like plastic waste exist, innovations in smart sensors and sustainable materials are paving the way for greener solutions.  By aligning with digital transformation and sustainability goals, single-use technologies will continue to evolve, offering next-generation solutions for the life sciences sector.
