20 L Rocker Bag
Our most widely requested rocker bag format — a single-use bag engineered for 20-litre rocking and wave-style bioreactor platforms, suited to mid-scale seed train and production workflows.
Low-Shear Mixing
Rocking motion provides gentle agitation, reducing shear stress on sensitive and shear-susceptible cell lines.
Wave-Platform Compatible
Engineered to fit standard rocking and wave-style bioreactor platforms across common working volumes.
20 Litre Working Volume
Sized for mid-scale seed train and production workflows on standard rocking bioreactor platforms.
cGMP Manufactured
Manufactured under controlled cleanroom conditions, gamma- sterilised, with full batch documentation.
Gentle agitation for shear-sensitive culture
Rocker bags are designed for use on rocking (wave-style) bioreactor platforms, where the bag is mounted on a tilting platform that creates a wave motion within the bag. This provides mixing and gas exchange without the mechanical impeller agitation used in stirred-tank systems, making it particularly suitable for shear-sensitive cell lines.
The gentler mixing profile of rocking platforms is frequently preferred for microcarrier-based adherent cell culture, where excessive shear can damage cells attached to carrier beads, as well as for certain primary and stem cell culture protocols where mechanical stress affects viability.
For applications requiring higher oxygen transfer at larger scale, our standard 3D Bioprocessing Bags on orbital platforms may be the more suitable format — see our 2D vs. 3D Selection Guide for a broader comparison.
Typical applications
- Shear-sensitive mammalian cell culture
- Microcarrier-based adherent cell culture
