WebAbstract – The aim of the study was to determine the characteristics of mixing time in a rocking single-use bioreactor equipped with a 2-litre bag-like container by the sensor method. Results have shown that the frequency of rocking movement has the biggest influence on the values of mixing time. Кеуwords – single-use bioreactor, wave ... WebCase study 1: bioreactor scale up from XDR-50 to XDR-200 In this example, a process is run in an XDR-50 with the settings listed in Table 1. slpm is standard liters per minute. Table 1. Process settings in XDR-50 When the process is scaled up to XDR-200, the tool calculates the operating parameters. An extract of the results is shown in Table 2.

WebSmall changes in the geometry of the mixer blades and in the aeration system can produce very different results in terms of mixing times, oxygenation of cultures or cell rupture. We are good at designing bioreactors because we combine a profound academic knowledge on aerodynamics and fluid mechanics with a large experience of optimizing chemical and … Web4 sep. 2024 · For a bioreactor with 4 L working volume, the maximum gassing rate would therefore be 4 L * 2 L L –1 min –1 = 8 L min –1. In cell cultures, by contrast, the maximum rate is often 10% to 15% of the working volume per minute as a way of keeping gas bubbles small and thus preventing foam formation and damage to cells from bursting bubbles. flights from moline il to seattle
