New 4L Bioreactor Bags

Now available: 4L bags for all CellMaker bioreactor systems.


The new 4L bags offer our customers the ability to scale down their pilot productions and scale up their bench scale experiments. Now with initial working volumes of 1.5L, scientists can create batches of cell culture at the quantities required for:

  • Process development
  • Cell culture seed generation
  • Generating characterisation quantities of protein
  • Scale-down troubleshooting

Compatible with all CellMaker bioreactor systems, our 4L single-use bags slot into your existing work flows to efficiently produce material in the perfect, low stress and easily controlled environment they need.


4L Bioreactor Bags:

  • Working volumes from 1.5L to 4L
  • Compatible with Regular, Dual, Plus and Low Flow CellMaker systems
  • Requires an 8L Enclosure
