Devices Constructed of the Same Materials
as Larger-Capacity Capsules and Cartridges
- Simplifies scale-up and minimizes revalidation; no need to change membrane materials during transition to pilot or production.
- Four membrane chemistries assure compatibility with a wide range of fluids:
- Supor® membrane has high flow rates and throughputs, and is ideal for solutions where low protein binding is required. Not recommended with some ketones.
- Fluorodyne® II membrane offers high flow rates and is ideal for applications where PVDF membrane is specified. Not recommended with some ethers.
- Ultipor® membrane provides broad solvent and chemical compatibility, and low extractables.
- Posidyne® membrane enhances bioburden and pyrogen removal from aqueous solutions.
- Integrity testable (water bubble point).
- Bacterial retention tested.
- Sterilized by gamma irradiation to eliminate potential contamination by EtO residuals.
- Drug development studies
- Determination of product compatibility and recovery
- Preliminary filterability testing
- Small-volume liquid sterilization
