How to optimize your shake flask and bioreactor cultures

Shakers and bioreactors are established versatile systems for cultivating microorganism, plant, and animal cells in suspension. Both methods aim at increasing the oxygen and nutrient supply in the medium to stimulate culture growth, but offer very different solutions in technique, volumes/throughput, control possibilities, and thus applications.

In this educational webinar, we will look at the biophysical background of both cultivation techniques, pros and cons, and areas of application. You will also learn how to optimize your process in shake flasks and bioreactors via proper choice of vessel type, vessel material, instrument configuration, and parameter settings. Additionally, we will introduce the use of feeding techniques bioreactors and have a glance on shakers too.
