Media and buffer preparation is a key part of the biopharmaceutical manufacturing process. Although this step doesn’t have to be carried out in sterile conditions, improving the powder transfer process makes preparation cleaner, safer, and more efficient while protecting personnel and cutting time and costs. The Issues of Powder Handling Powder ingredients for media and buffers have historically been transferred using scoops and weighed and mixed in buckets or open top bags. Many companies are starting to move to single-use…

Scale-Up of Plant Cell Suspension-Based Processes
In the field of research and development into the production of bioactive compounds, there is incredible demand for small-scale cultivation systems that operate in the liter range (1, 2). Single-use bag bioreactors can close the gap between cell and media screening devices (at scales of up to several hundreds of milliliters) and pilot bioreactor systems at scales larger than several hundreds of liters (3). The incubator shaker Multitron Cell with ShakerBag Option, in particular, represents an easy and economical solution…
Enhanced Assurance of Supply for Single-Use Bags: New Flexsafe Bag Family
Growing adoption of single-use bags for the production of biopharmaceutical drugs raises new challenges, including consistent product quality, improved assurance of supply, robust change management, and business continuity planning. In close collaboration with resin and film suppliers, Sartorius Stedim Biotech’s polymer scientists and biologists have followed a quality by design (QbD) program for the development of a completely new polyethylene film S80 thus achieving consistent performance of the new Flexsafe bags for all bioprocess steps and applications. The partnerships and…
