Media, inoculum and harvest transfer are illustrated within closed bags and tubing. Gas supply and exhaust have distinct roles and should not be interpreted as one recirculation line. The image does not validate actual sensor/gas routing or any supplied product’s exterior, ports, sterility or performance. Rocking and stirred systems use different dedicated hardware. Verify bag/film, connections, gas filters and platform compatibility from documentation. Display traces are illustrative.

The product illustration shows a rocking-bag shape as an example. Gas supply, exhaust, and liquid paths are shown separately. For stirred systems, separately check compatibility with the dedicated impeller and drive.
These conceptual views explain flow direction. Actual piping, wiring and physical flow rates require a separate design.
01 — PROCESS
Where does each step fit?
Define the intended use and conditions to identify the required role of each item.
Culture and process control
Manage rocking or stirring, temperature, gas supply and exhaust, and monitor pH, dissolved oxygen (DO) and growth.
Harvest and next stage
Define the harvest path and transfer conditions to suit the intended recovery of cells or culture fluid.
02 — SELECTION
What should be selected and verified?
A bioreactor bag is more than a storage vessel. Select bag geometry, gas supply and exhaust, mixing, sensors and culture equipment together to suit the cells and culture method.
Scroll horizontally to review all columns.
| Bag or assembly function | Item to review | Selection evidence |
|---|---|---|
| Select the culture method | Rocking or stirred | Suspension or adherent culture, working volume, and the combination of culture equipment and bag |
| Gas transfer and exhaust | Gas supply path | Oxygen demand, CO₂ removal, exhaust filters, and condensation and pressure management |
| Monitor culture conditions | pH, DO and temperature | Compatibility of sensor ports, optical patches and readers, and calibration and verification procedures |
| Maintain cell growth and yield | Effects of film and sterilization | Growth comparisons for the cells used, medium contact conditions, and extractables and leachables evaluation |
| Scale up culture | Compare processes across scales | Changes in mixing, gas transfer and shear, and indicators of cell growth and quality |
Volume or film name alone is insufficient. Review the actual fluid, contact conditions, equipment compatibility and supplier evidence.
03 — OPERATING CHECKS
Use operating data to identify improvements.
Check exhaust-filter wetting and condensation
Increased exhaust resistance can affect bag pressure. Adapt gas flow, condensation management, alarms and response procedures to the equipment conditions.
Reassess culture even when only the bag changes
Changes in fluid-contact film, additives, sterilization conditions and storage duration can affect cells. A comparative evaluation of the actual cell and medium combination is required.
Similar shape does not establish equipment compatibility
Check tray attachment, rocking settings, impeller and drive, and sensor locations. Do not assume a bioreactor bag is a universal replacement component.
04 — QUESTIONS
Frequently asked questions
How do rocking and stirred systems differ?
Rocking systems mix fluid through tray motion; stirred systems use an impeller. Their mixing and gas-transfer mechanisms differ, so select according to the cells, scale and equipment.
Can cells be cultured in a storage bag?
Suitability for storage does not establish suitability for culture. A culture configuration with assessed gas transfer, mixing, cell growth, sensors and sterile boundary is required.
05 — APPLICATION REVIEW
Prepare the conditions for a technical discussion.
These details help narrow the configuration and the evidence to review.
- Cell type, medium and culture method
- Inoculum, working volume and culture duration
- Equipment manufacturer and model, and current bag code
- Gas, pH, DO and temperature control conditions
- Harvest method, target yield and quality indicators
Product types and confirmed supply scope are different.
This page explains selection considerations by application. It is not a commitment to supply every type, size or manufacturer’s product shown. Share the manufacturer and product code, or your configuration requirements, to discuss supply availability and outstanding checks.
- Existing product code
- Required volume, ports and tubing
- Equipment and support vessel
- Expected quantity and requested timing
