The Pellicon® 2 product line was designed with process scale-up and applications development in mind. The series of devices includes the long established Durapore® hydrophilic PVDF microfiltration membrane, well known for its exceptional combination of high flux, low protein binding and high product recoveries.
Benefits
- Leading-edge void-free membranes to match virtually any separation challenge
- Short flow path for higher flux and higher resolution separation capability
- Choice of flow channel configuration providing process optimization capability
- Predictable, fast, scale-up
- True linear scalability from laboratory size modules to industrial assemblies for processing thousands of liters
Applications
- Clarification – of protein solutions, polysaccharide solutions, virus suspensions/cultures, cell lysates and pre-column streams
- Harvesting – of cell cultures and colloidal suspensions
- Harvesting and Washing – of colloidal suspensions, bacterial cells or viral cultures
