The Whatman™ Puradisc™ Non-Sterile H-PTFE Syringe Filters are high-performance filtration devices designed for rapid and reliable sample preparation in laboratory workflows. Featuring a hydrophilic PTFE (H-PTFE) membrane, these filters combine broad chemical compatibility, high flow rates, and excellent particulate retention, making them ideal for both aqueous and aggressive organic solvents.
Engineered for routine laboratory use, Puradisc™ filters are particularly suited for HPLC and UHPLC sample preparation, as well as applications in biological analysis, protein filtration, and spectroscopy. Their robust design and cost efficiency make them a dependable “workhorse” solution for high-throughput laboratories.
