thawing process in a reproducible procedure, which offers important benefits in situations where there is a higher de-mand for standardization and documentation of the thawing process. They are also well suited for situations where water baths are impractical [6,7]. The most important drawback to dedicated thawing devices is the upfront investment

[2]. This strain has an ampicillin resistance gene (bla) encoded on a plasmid. A concentration of 0.1 g/L ampicillin must be maintained in all cultures, since absence or low concentrations of ampicillin will result in plasmid loss [3]. Therefore, from inoculum preparation in shake flasks to fermentation runs in 3 L vessels, we always added 0.1 g/L

Leachables and extractables are defined as substances that can either be extracted from plastic materials under harsh conditions (e.g. extreme temperatures, presence of solvent) or released spontaneously under standard conditions. They may originate from compounds used in polymer manufacturing such as softeners, stabilizers, and antioxidants. Espe-

cultivation bottlenecks. Introduction Many applications are well served by the cultivation of bacteria or yeast in shake flasks and cells in dishes or T-flasks. Bioreactors and fermenters, however, improve productivity and save work, time, and lab space for scientists, who: • need large quantities of cells, microbes, or the products they express

Power number (Np) The (impeller) power number (also known as Newton number) is a dimensionless number associated with different type of impellers. Np is commonly used to calculate impeller power consumption during bioprocess scale-up [2]. We determined the power number and P/V values at various Used with 1 L fermentation glass vessel Used with 10 L

Cell Culture Scale-Up in Stirred-Tank Single-Use Bioreactors

The stirred-tank bioreactor design is relatively easy to describe with classical engineering approaches (Figure 1). Parameters to describe this vessel geometry include impeller diameter, vessel diameter, liquid height, and ratios thereof. It is the bioreactor design for which most research on Figure 1: Stirred-tank bioreactor design d D i h ...
