Fluid Dynamics of a Single-Use , Stirred-Tank Bioreactor for Mammalian Cell Culture @inproceedings{IsailovicFluidDO, title={Fluid Dynamics of a Single-Use , Stirred-Tank Bioreactor for Mammalian Cell Culture}, author={B. Isailovic and Michael Kradolfer and B. Rees} }Xcellerex XDR MO single-use stirred-tank fermentors | CytivaSingle-use, stirred-tank fermentor systems for growing microbial cultures, in two sizes: 50 L and 500 L. Microorganism growth performance comparable with conventional stainless steel fermentors. Powerful mass transfer from a high-power input, two-stage impeller. Oxygen transfer capacity that supports high-density fermentation.What should the tip speed be in a stirred tank?Operators often apply a notional tip-speed limit of 1.5 m/s as a general guide for stirred-tank bioreactors. It is generally thought that cell damage may begin above that value ( 5 ), even though no substantive evidence supports such a restrictive guideline across all mammalian cell culture processes.See all results for this question

What is stainless steel stirred tank reactor?

Those changes typically provide more robust processes and increased production flexibility. For mammalian cell culture, cleanable multiuse glass or stainless steel stirred-tank reactors (STRs) have been used successfully for growth of suspension-adapted cell lines in both small- and large-scale systems.See all results for this questionWhat is a stirred tank?A stirred tank typically contains one or more impellers mounted on a shaft, sometimes baffles, and other internals such as spargers, coils and draft tubes.See all results for this questionWhat are the features of a 100 L stirred tank bioreactor?Here we discuss the major design features of a 200-L single-use stirred-tank bioreactor (Pall Allegro STR 200) and present results of studies on its fluid dynamics through measurement of physical parameters that are critical to mammalian cell culture. Our studies confirmed the following: Precise and homogenous control of temperature.See all results for this question

Stirred-Tank Bioreactors - an overview | ScienceDirect Topics

In general, the stirred tank bioreactor has several advantages for the cultivation of shear-sensitive cells: existing industrial capacity, proven performance, ease of maintaining homogeneous conditions, and ease of scale-up and control.Stirred Tank Bioreactors - Cell Culture | Pall CorporationPalls high performance single-use, stirred tank bioreactors bring superior mixing and mass transfer, and support higher cell densities. The design and development of single-use equipment that fully satisfies the performance, functionality, and validation requirements for user process systems can be particularly difficult for complex, automated equipment such as bioreactors.Stirred Tank - an overview | ScienceDirect TopicsNumerous parameters like tank and impeller shapes, the aspect ratio of the tank, the number, type, location and size of impellers, the degree of baffling, etc. provide unmatched flexibility and control over the performance of stirred reactors and also present great challenges to the design and scale-up (or scale-down) of such reactors.

Single-use Stirred Tank Bioreactors - Pall

Just a few of the many advantages of the square single use bioreactor: Improved handling - Reduced operator intervention and processing time. Excellent mixing performance - Shorter mixing times < 30 seconds and great power input for high kLa and CO 2 stripping. Optimized cleanroom footprint - Even the 2000 L bioreactor fits under 3 meters.Performance Qualification of a Single-Use, Stirred-Tank design and performance of single use stirred tankSep 15, 2016 · In a previous publication (2), we described the design features of a single-use, 200-L, stirred-tank bioreactor (Photo 1) based on a customized, cubical biocontainer with internal baffles and a large, direct drive, pitched impeller with three blades. Data from our studies on the bioreactors fluid dynamics showed that the system could provideOn the fluid dynamics of a laboratory scale single-use design and performance of single use stirred tankMay 24, 2014 · 1. Introduction. In the last 15 years the biopharmaceutical industry has experienced a significant increase in the uptake and utilisation of single-use technologies, primarily driven by the need for a reduced time to market, an enhanced degree of flexibility and attenuated risk of cross-contamination (Business Insights, 2007).Since the release of the first rocked bag by Wave Biotech US in 1996 design and performance of single use stirred tank
