Membranes Designed for the Stringent
Requirements of Mobile Phase Filtration
- Membranes are identical in composition and quality to those used in Pall’s HPLC-certified Acrodisc® syringe filters
- HPLC certification assures that the filters will not add artifacts to your analysis
- GH Polypro membrane is the best choice for filtering mobile phases
- PTFE membrane provides the ultimate in chemical compatibility for filtering harsh chemicals and HPLC mobile phases
