| Flow rate range** | 1 - 5 mL/min | 75 – 375 mL/min | 0.6 – 3 L/min | 2 – 10 L/min |
| Intended use | Scaled down laboratory model to screen and fine-tune parameters. | Intermediate scale adsorber, intended to verify and adjust operating parameters. Pilot may be used for small-scale clinical and commercial manufacturing. | Process scale adsorbers designed for full-scale GMP manufacturing of proteins | |
| *Based on typical process streams and loading up to 10 kg mAb/L membrane. Loading capacity is not limited to 10 kg mAb/L and depends on the total impurity content. **Typical flow rate range is based on 5-25 membrane volumes/minute. Specific flow rates can be determined to accommodate process requirements (e.g. maximum back pressure, improved process time, etc.). |
