Membrane Stack Disc Filters
For Initial Filterability and Compatibility Studies
- Used for a wide variety of applications including clarification and prefiltration, sterile filtration, and virus removal.
- Membranes contain the same materials of construction as larger capsule and cartridge filters. Simplify scale up and minimize requalification; no need to change materials during transitions to pilot or production scale.
- Five membrane types offered to assure compatibility with a wide range of fluids and applications:
- Fluorodyne® II membrane offers high flow rates and is ideal for applications where low protein binding is necessary. Not recommended with some ethers.
- Supor® membrane has high flow rates and throughputs and is ideal for solutions where low protein binding is required. Not recommended with some ketones.
- Ultipor® membrane, the industry standard for pharmaceutical filtration, provides broad solvent and chemical compatibility, and low extractables.
- Posidyne® membrane enhances bioburden and pyrogen removal from aqueous solutions.
- Preflow™ media is ideal for the prefiltration of biological fluids including cell culture media, serum based products and protein solutions.
- Filtration of small volumes
- Drug development studies
- Validation studies
- Determination of product compatibility
