The Next Step in Implementing Disposables

Biopharmaceutical manufacturers face increased pressure to commercialize new drugs faster and at a lower cost. As a result, production demand is outpacing available manufacturing capacity. To meet existing and future demand and maintain a competitive advantage, many manufacturers are striving to develop increased efficiencies within their manufacturing processes. This is where single-use systems — particularly single-use transfer lines — can deliver significant value, including added flexibility, improved production yields, and increased cost savings. The trend today is toward transfer lines…

Batch and Fed-Batch Cell Culture

Figure 1. How well does absorbance correlate with cell density and viability measurements in batch and fed-batch cell culture? As expected in science and nature, the answer depends on a set of factors. Many people working with batch or fed-batch cell culture will reference discrete offline measures of cell activity. Total cell density (TCD), viable cell density (VCD), and percent viability can be evaluated offline using a hemocytometer and accepted trypan blue exclusion method. Cedex® and Vi-CELL™ are two examples…

Single-Use Solutions for Complex Processes

While industry is rapidly shifting from stainless steel vessels and hard-plumbed processes to single-use bioreactors and TFF filters, the transition between the multiple process steps remains complicated and time-consuming, often requiring fluid transfers, disrupting sterile barriers, and cleaning protocols. The simple solution to a complex process is connectivity: a continuous flow-path that interconnects all the process steps by means of a sterile singleuse process manifold. Spectrum Laboratories incorporates process filters, reservoir bags, flexible tubing, and other critical elements into a…

Designed for Advanced Application

Emerging lifestyle diseases and an aging population are creating a number of major health challenges. Over the past few years, the food industry has been more focused on functional foods, those intended to be consumed within the normal diet but containing biologically active components with physiological benefits intended to reduce certain chronic diseases. This US$35 billion market has been steadily growing at 8-14% per year, as estimated by the Food and Agriculture Organization of the United States (FAO). Although the…

Process Control in Single-Use Bioreactors

The development of single-use bioreactor technologies is focused on bringing new designs onto the market for effective oxygen transfer and cultivation of not only cell culture processes, but also microbial cultures. The advantages of disposable technologies are: ease of use, prevention of cross-contamination, labor and capital investment savings, reduced qualification and validation, and increased flexibility. The costs of disposables are lower compared with conventional stainless-steel bioreactors because the capital investment is lower. Therefore, the need is reduced for qualification and…
