Allegro STR Single-Use Bioreactor

Single-use lower agitation type bioreactor. Suitable for suspension cell culture applications. High stirring capability! Safe at a total height of under 3m even for 2,000L.

The Allegro(TM) STR single-use bioreactor achieves high mixing capabilities and a low overall height of less than 3 meters, even with a capacity of 2,000 L, thanks to its rectangular culture vessel, which surpasses the performance of traditional cylindrical culture vessels. ■ High Mixing Capability The effective baffle effect of the rectangular culture vessel and the elephant ear-shaped mixing blades allow for the desired oxygen transfer rate to be achieved at lower stirring speeds than before. This results in high kLa and P/V values, reducing shear stress on cells during cultivation at lower stirring speeds. ■ Geometric Similarity Across All Scales, Including Mixing Blades Maintains a similar shape across all scales of 50, 200 L, 500 L, 1,000 L, and 2,000 L. ■ Scalable with Constant P/V Due to geometric similarity and the ability to achieve high P/V values, scaling up with constant P/V is possible. ■ Overall Height Below 3 M Even at 2,000 L Significantly reduces the need for high-altitude work, ensuring the safety of operators. ■ Easy Installation of Dedicated Culture Bags After transporting the single-use culture bag into the culture vessel, it can be set up within 30 minutes with minimal operator intervention.
