LabExact Tri-Layer PVDF Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10405

Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The PVDF membrane clarifies samples at the rated pore size while tolerating common chromatography solvents without degradation and repels water for dependable gas and vent filtration. Polyolefin construction sheds virtually no extractable material into the sample while standing firm against aqueous acids, bases, and alcohols during regular handling and holds its seal true run after run. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Gamma irradiation sterilization causes no chain scission unlike polypropylene membranes
• Absolute pore rating ensures reproducible results between test runs
• Ethylene oxide sterilization cycles leave pore integrity and flow performance intact
• Mechanically durable membrane holds integrity under filtration pressure
• Organic solvent resistance beats PES or nylon at comparable pore size

Housing Characteristics

• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.
