Measuring Pressure at Very Low Levels with High Accuracy in Single-Use Systems: Improved Performance and Single-Use System Testing

Measuring pressure in single-use systems (SUS) has become an integral part of both upstream and downstream bioprocess operations. Articles have been published on filtration applications (1), and integration into other SUS has been widely adopted. Additionally, information is available on low-pressure applications such as how to prevent overpressurization in single-use bioreactors (2). However, as users and applications both become more sophisticated, improved performance is sought for low-pressure applications (<1 psi) such as in single-use bioreactors. The reasons are two-fold: First,…

Implementing Flexible, Scalable, and Cost-Efficient Bioprocess Platforms: A Proven Project Management Approach

Although significant scientific progress has been made in the biotechnology industry, it has lagged behind other sectors — such as aviation and automotive — in developing, scaling up, and industrializing products coming out of R&D. The goal is to implement robust and reliable manufacturing processes for good manufacturing practice (GMP) market supply cost-effectively. But manufacturing methods for biologics have remained unchanged for decades, with large-scale, capital-intensive stainless steel facilities taking three to five years to build and remaining both energy…

The Single-Use Watering Hole: Where Innovation Needs Harmonization, Collaboration, and Standardization

Within the past few years, the single-use technology (SUT) arena of the biopharmaceutical industry has exploded in growth. Leading organizations have predictably and understandably stampeded to the “watering hole” of single-use to drink up the advantages that disposable components offer over traditional multiuse parts and technologies. The initial value and risk-reduction results are being realized — but not without the emergence of other trade-offs. End users continue to call for standardization in emerging areas of the industry while also recognizing…

Exploring Options for Dual Sourcing of Single-Use Components

As the bioprocess industry progressively adopts single-use technologies for large-scale manufacturing (1, 2), biomanufacturers’ increased reliance on integrators for critical production equipment continues to raise concerns about supply chain security. The need to mitigate risks associated with the supply of single-use components (e.g., bioreactors, aseptic connectors, tubing, filters) has led to growing interest in the dual sourcing of those materials. To that end, integrators and end users alike are exploring the definition of functionally equivalent products, how functional equivalency can…

Sterilization Effects on Elastomer Characteristics and Functionality in Parenteral Delivery Systems

To drive efficiencies in producing parenteral drug products, manufacturers are using containers and closure components that are received sterile and ready to be introduced into filling lines. The effects of sterilization on the properties of ready-to-use (RU) components must be assessed to ensure proper processing techniques and suitability over the components’ intended shelf lives. Sterile-drug manufacturers must determine the best sterilization method for components based on their respective drug products and processes. Critical areas of risk include potential changes related…

Trends in Setting Single-Use Technology Standards

The biopharmaceutical industry now incorporates single-use (SU) technology and systems in most production processes based on cell culture (1, 2). Implementation of such technologies has led to the availability of prepackaged and sterilized systems complete and ready for use with preinstalled mixers and monitoring probes. From upstream process- material preparation through final-product formulation, biopharmaceutical sponsors are increasingly presented with numerous SU solutions that support all major production platforms (3–5). The number of SU materials and suppliers in biopharmaceutical manufacturing has…

Integrated Optical Single-Use Sensors: Moving Toward a True Single-Use Factory for Biologics and Vaccine Production

Through the past decade, single-use bioreactors for culturing mammalian and insect cells have been widely adopted in preclinical, clinical, and production-scale biopharmaceutical facilities (1, 2). With such bioreactors in operation, monitoring and control of process parameters is vital for ensuring critical quality attributes (CQAs) of biologicals or vaccines are met for production of a safe product. Traditionally, bag-based and bench-top vessels have been fitted with conventional pH and dissolved oxygen (DO) probes similar to those used in stainless steel or…

Designing Single-Use Solutions for the Future: A Conversation with Christel Fenge

Recently, BPI publisher Brian Caine and editor in chief Anne Montgomery had the opportunity to talk with Christel Fenge, Sartorius Stedim’s VP of marketing for fermentation technologies, in the Göttingen, Germany, Sartorius facility. They began by talking about fermentation technology, a topic that led them to touch upon a number of key issues in the biopharmaceutical industry. Fermentation Technology Caine: Because this special issue focuses on fermentation technology, let’s begin by talking about some recent technological improvements and what impact…

Robust and Convenient Single-Use Processing: The Superior Strength and Flexibility of Flexsafe Bags

With the increased use of disposable bioprocessing bags in all critical process steps of the biopharmaceutical drug production, there is a growing requirement for high-quality, robust, and easy-to-handle bioprocessing bags. The new generation of films and bags must combine multiple mechanical, physical, and chemical properties to make these products suitable and scalable for all processing steps in upstream, downstream, and final filling operations, including cell culture in rocking motion and/or stirred-tank, single-use bioreactors as well as storage, mixing, shipping, and…

Enhanced Assurance of Supply for Single-Use Bags: Based on Material Science, Quality By Design, and Partnership with Suppliers

Growing adoption of single-use bags in commercial production of biopharmaceutical drugs raises new challenges for bag suppliers and drives the need for consistent product quality, improved assurance of supply, robust change management, and business continuity planning. In close collaboration with resin and film suppliers, polymer scientists and biologists at Sartorius Stedim Biotech have followed a stringent material science and quality by design (QbD) program to develop a completely new polyethylene film and to achieve consistent performance of new Flexsafe bags…
