Due to its beneficial attributes, silicone is utilized today in countless medical and pharmaceutical applications. It is the preferred material for sealing complex systems as well as for peristaltic and pharmaceutical tubing. Silicone is available in a wide range of durometers, from super soft (000) to relatively hard (90 Shore A), and can withstand a range of temperatures. The silicones readily available in today's market differ not only in their level of approval for medical and pharmaceutical applications, but also in their crosslinking mechanism. There is a clear distinction between platinum-cured and peroxide-cured silicones. Learn More

In the past 15 years, the biopharma industry has seen a steady uptake in the use of single-use technology in bioprocessing. Single-use technology is being developed for nearly every application from upstream mixing and bioreaction to downstream perfusion and chromatography. In the pursuit of personalized medicine and continuous processing, single-use is being hailed as the only way to achieve these goals. Does this mean an end for traditional bioprocesses that employ stainless steel technology? Is stainless steel already being considered a legacy product as we journey towards fast, closed and process-intensified manufacturing systems?

Marc Pelletier, Director of CRB, and Mark Embury from ASEPCO, part of Watson-Marlow Fluid Technology Group (WMFTG), discuss whether stainless steel is a technology of the past. Learn More

This paper presents various software based approaches suitable for the design of knowledge-based monitoring of biotechnological production processes. These processes require special treatment with respect to the complexity in biochemical reactions which make the design and construction of reasonably complex and practically usable mathematical models rather difficult. Additional complexity arises from the lack of industrially viable sensors for on-line measurement of key process variables. Software sensors which often use tools from the field of artificial intelligence represent one of the suitable approaches for the overcoming of the above mentioned limitations for its ability to utilize effectively both quantitative and qualitative knowledge about the monitored bioprocess. Learn More

Process intensification strategies are needed in the field of therapeutic protein production for higher productivities, lower cost of goods and improved facility utilization. This work describes an intensification approach, which connects a tangential-flow- filtration (TFF) based pre-stage perfusion process with a concentrated fed-batch production culture inoculated with an ultra- high seeding density (uHSD). This strategy shifted biomass production towards the pre-stage, reaching up to 45 × 106 cells/ mL in perfusion mode. Subsequently, production in the intensified fed-batch started immediately and the product titer was almost doubled (1.9-fold) in an equivalent runtime. Learn More

This video, produced by G-Con, tells the story of how prefabricated PODs were delivered in 8 months to Rubius Therapeutics' cGMP facility in Smithfield, Rhode Island. Meeting their aggressive timeline and providing speed to market for clinical manufacturing.

In a recent typical experiment, eight bioreactors were sampled three times per day with feedback control for multiple separate nutrient feed solutions per vessel, based upon independent metabolite triggers. Over the course of the run each vessel was triggered feeds 35-40 times with feed volumes ranging from 2 to 40 mL for over 300 automated feeds across the eight vessels. Refined data extraction templates streamlined data imports and the electronic notebook system, and PI integration can enable remote monitoring. The enhanced system capabilities are being increasingly leveraged to support ongoing process development efforts.

Althea, an industry leading CMO specialized in cGMP manufacturing, analytical development, aseptic filling and protein delivery technologies was looking to evaluate flow systems for multiple applications throughout their facilities. One of the main issues looking to be addressed was the replacement of weigh scales for volume measurement with flow sensors. To that end, three competing flow sensor set-ups were configured and tested for both their measuring performance and suitability as a viable solution for the application.

Microbial contamination monitoring for process control in the pharmaceutical industry in water for injection (WFI) or pure water (PW) has relied on laboratory-based methods developed a hundred years ago. This laboratory-based approach has a number of potential sources of contamination, even when handled by highly skilled personnel, including the sample port, sampling container and testing procedure.

In this case study we discuss how a leading biopharma company in France observed positive results on its laboratory-based testing method for microbial monitoring, leading to suspicion of microbial contamination in the water system. As a root cause analysis was being conducted, the company suspected that biofilm was forming in the system, leading to positive test results. The plant turned to the Mettler Toledo Thornton 7000RMS Microbial Detection Analyzer to provide real-time analysis of their water system for process control and to immediately identify any out of specification events.

This video, produced by Hamilton Process Analytics, illustrates how traditional pH sensor management in a production process is costly and labor intensive - the cost of the sensor only accounts for 20 percent of total operational cost.

The Bio-Process Systems Alliance (BPSA) has published a 20-page Market Data Report - A Data-Driven Assessment of Single-Use System Reliability: 2016-2018. The report, funded and overseen by members of BPSA, used a confidential third-party to undertake this priority project that now allows SUS end-users to quantitatively assess the overall performance of SUS in order to make comprehensive business decisions. Additionally, this initiative allows each SUS supplier to benchmark their own performance against industry averages. Both end-users and suppliers can then target improvement initiatives toward complaint rate categories that align with their specific business or quality goals. Learn More

This video, produced by IDEX Health & Science, discusses real-time antibody titer monitoring for bioprocessing using their Tridex protein analyzer.

In today's state-of-the-art bioprocessing systems, one of the most essential subsystems provides gas management for the gases necessary for cellular metabolism. At the heart of the gas management subsystem is the thermal mass flow controller (MFC), advanced digital technology that precisely measures and controls process gas delivery. This new white paper describes the inner workings of digital MFCs with an emphasis on their robust ability to gather, generate and communicate a broad range of process data. The white paper focuses on practical ways to utilize MFC device data to improve process control, system uptime, diagnostics, preventive maintenance and, ultimately, bioprocessing yields. Learn More

This technical note, authored by IDEX Health & Science, describes a novel, compact device, the Tridex Protein Analyzer, capable of rapid, automated at-line measurement of antibody titers from stirred bioreactors using an aseptic sampling device. Assay linearity and accuracy were evaluated over a measurement range of 0.1 to 6.5 g/L using a simulated cell culture titer curve spiked with bovine serum albumin (BSA) and human IgG. Manual and automated aseptic sampling measurements using the Tridex analyzer compared very favorably with a commercial Protein A HPLC system. Excellent intra-assay precision (CV < 3%) was demonstrated for both off-line and at-line measurements with the Tridex analyzer. Learn More
