FAQs - Biostat STR® Generation 3
Bioreactor bags are the single-use equivalent to stainless steel vessels - the actual chamber where the cell culture is placed. They are ususally provided sterile and ready to use following installation in the bag holder. A bioreactor bag is typically equipped with all necessary connections and lines for gassing, media feeds and sampling. Sensor probes for process analytical technologies can either be inserted through specific ports or are directly included in the bag assembly as single-use sensors.
As bioreactor bags are made from plastic, careful considerations of extractable and leachables (E&L) are needed. Sartorius has full control of its propietary range of Flexsafe film material from resin formulation up to bioreactor bag assembly and can thus provide consistent quality and comprehensive E&L data.
Single-use bioreactors are available in a range of volumes, starting as low as 10 mL of working volume up to several thousand liter capacity. Thus, single-use bioreactors can be used in all applications from research to process development, pilot and clinical scale and ultimately, commercial manufacturing.
STR stands for stirred-tank reactor. It describes a bioreactor type where mixing is achieved through a central stirrer element inside the culture vessel. STR type bioreactors are available as stainless steel and single-use equipment. They are well known for excellent scalability, as constant height to diameter ratios and vessel diameter to impeller diameter ratios can be achieved.
We at Sartorius often refer to our Biostat STR® single-use bioreactors as STR, because these bring all the benefits of traditional stirred-tank reactors in a user friendly single-use system.
