0.2µm AseptiCap® WL/WS-γ Small
MDI AseptiCap® WS-γ are low protein binding hydrophilic PVDF gamma sterilizable membrane inline capsule filters, designed for sterile filtration of very small fluid volumes in formulation and process development labs.
These capsule filters are validated to meet compendia and regulatory requirements and are well characterized. They meet key process requirements such as absolute retention efficiency, extremely low extractables, high throughputs, wide chemical compatibility and other important characteristics.
- Absolute retention
- 100% integrity tested
- Low protein binding
- Low extractables
- Very low hold up volume
Sterile Filtration of:
- Antibodies
- Protein Solutions
- Buffers
- Heat labile additives
- Vaccine concentrates
- Small Volume Parenterals
