PendoTECH Sensors and Industry 4.0: Integrating a PendoTECH Single-Use Sensor System with a Digital Highway

Biopharmaceutical manufacturing is evolving with the progression of Industry 4.0. Industry 4.0 refers to the ongoing “fourth industrial revolution,” which is transforming modern manufacturing and production practices through the use of “smart” technology. This is appealing especially to the biopharmaceutical industry, where production can be a long, meticulous, complex process, and optimizing manufacturing procedures is critical for success. As a leading supplier of single-use technology for the biopharmaceutical industry, PendoTECH recently has explored how its products can be integrated easily…

Validation of a Next-Generation Single-Use Turbidity System

Turbidity describes the relative clarity of a liquid as the result of suspended solids. Instruments that measure turbidity typically use a beam of light to detect particles by measuring the difference between the amount of light emitted from the light source and the amount that is received by a detector. Such measurements are affected by the size, shape, and number of particles in a sample of liquid because those solids scatter the incoming light, which provides an apparent absorbance that…

Measuring Cell Density in HyPerforma S.U.B.s with ABER Futura neotf
Single-Use Sensors

Monitoring critical process parameters (CPPs) and key performance indicators in bioreactor control systems is crucial to ensure proper cell growth and protein production. Today, most of the major biopharmaceutical companies employ capacitance measurement, in R&D and through process development to manufacturing. Owing to the increased use of single-use bioreactors and building on Aber’s experience with single-use capacitance sensors, the latest Futura neotf single-use capacitance sensors have been specifically developed for integration into Thermo Fisher Scientific bioprocess containers (BPCs) for use…

eBook: Bioreactor Sensors —
Inside the Dynamics of Cell Culture

Cell culture monitoring can fall into something like a “black box” conundrum. Efforts to measure key parameters such as pH, glucose, and even cell density require sampling and removal of the contents from a bioreactor. But that procedure can expose both a process and an operator to contamination risks. Emerging bioreactor sensors are designed to address some of those challenges, but the rapid adoption of single-use technologies and the rise of perfusion cell culture have presented obstacles to their implementation.…

How Capacitance Measurement Can Improve Viral Vector and Virus-Based Vaccine Production

With the increasing development of viral vector and virus-based vaccines, technologies that help to manufacture and scale up these types of vaccine quickly and cost-effectively have become more critical. By accessing this special report from Aditya Bhat, a capacitance technology expert at Aber Instruments, you will find out how in-line capacitance measurement can produce a detailed fingerprint of cell culture processes and how that can benefit vaccine production. From case studies involving baculovirus, AAV, and measles, you will discover why…

Improving Cell Manufacturing Outcomes Using In-Line Biomarker Monitoring

Cell-based advanced therapies are changing modern medicine dramatically. Immunotherapies such as chimeric antigen receptor (CAR) T-cell therapies are treating different forms of cancer. Gene therapies are reversing the course of inherited diseases, and tissue-engineered medical products are restoring, maintaining, and replacing damaged organs (1–4). The development of new advanced therapies is booming. As of January 2020, the US Food and Drug Administration (FDA) has reported more than 900 investigational new drug (IND) applications for cell and gene therapy products. However,…

Bioreactor Automation Driven by Real-Time Sensing: Enhancing Productivity Through Accurate, Efficient Glucose Control

In the quest for improved quality and productivity in drug manufacturing, the industry is moving toward increasing use of bioreactor systems with real-time integrated monitoring and advanced analytics that can enable automation, drive performance, and improve data-rich quality control. However, there are multiple options for sensors and technologies that monitor important cell-culture variables or critical process parameters (CPPs). Furthermore, cell culture vessels can be disposable single-use bioreactors (SUB) or reusable glass or stainless-steel models. They can operate in stirred tanks,…

Practical Considerations for Statistical Analyses in Continued Process Verification

Several statistical techniques can be used to assist in monitoring biopharmaceutical product quality attributes as part of continued process verification (CPV) activities. These include run charts, control charts, and capability analyses. Below, I provide an overview and recommendations on statistical strategies when developing a CPV program, considering the expected behavior of manufacturing results in the biopharmaceutical industry. Presence of Autocorrelated Data In a previous study, I highlighted the tendency for data to be positively autocorrelated (values are closely related to…

Ultrasonic Flow and Bubble Sensors: Optimize Process Quality in Single-Use Bioprocessing Applications

Process monitoring in laboratory and production environments enables continuous control and optimization of critical process parameters. Hence, the early detection of errors is an effective means of increasing process efficiency and reproducibility, improving quality and safety parameters, and reducing long-term costs. Highly precise and flexible noncontact clamp-on flow and bubble sensors are useful instruments to fulfill these goals. They can be applied effectively to buffer and media preparation, chromatography and filtration systems, bioreactors and fermentors, feed and transfer lines, and…
