Syringe filters with PTFE membrane are ideal for the filtration of organic solvents and harsh solvents in HPLC (0.45 m) and UHPLC (0.2 m) sample preparation. Filtration helps protect sensitive parts of analytical instrumentation from particulate build-up, extending the life of chromatography columns and reducing system downtime. PTFE is a hydrophobic membrane and is not suitable for the filtration of aqueous solutions, however these syringe filters are ideal to use in venting applications. Designed for the filtration of sample volumes up to 10 mL. The syringe filters are HPLC certified for low levels of UV-absorbing extractables, ensuring accurate and reliable results.Pall 13 mm syringe filters are available with a male slip luer outlet or a proprietary minispike outlet. The minispike allows for easy handling with a HPLC vial and offers a reduced hold-up volume. This product is not approved for use in medical, clinical, surgical or other patient applications.
