• Membrane Type: Hydrophobic PTFE: The use of hydrophobic PTFE (Polytetrafluoroethylene) is a significant advantage. PTFE is renowned for its exceptional chemical resistance, making it compatible with a vast array of organic solvents, acids, and bases. Its hydrophobic nature means it is ideal for filtering non-aqueous solutions; for aqueous solutions, it would require pre-wetting with a compatible solvent.
• Filter Diameter: 25mm: The 25mm diameter provides an optimal surface area for efficient filtration of typical syringe volumes, balancing speed and capacity. This size is a common standard in laboratory settings.
• Housing Material: Polypropylene: The polypropylene housing is a robust and chemically inert material. It is lightweight yet strong enough to withstand reasonable pressure during manual syringe filtration without failure.
• Connections: Female Luer Lock Inlet and Standard Male Slip Luer Outlet: These standard Luer connections ensure universal compatibility with most laboratory syringes and collection devices. The Luer lock provides a secure, leak-proof connection, essential for preventing sample loss or contamination.
• HPLC Certified: This certification is a significant indicator of quality. It means the filters have been tested and confirmed to have low levels of UV-absorbing extractables. This is crucial for analytical techniques like HPLC, where even trace amounts of contaminants can interfere with detection and lead to inaccurate results.
• Unit: Pack of 1000: The pack of 1000 units signifies a high-volume, cost-effective solution for laboratories with consistent filtration needs. This bulk packaging reduces the frequency of reordering and storage management.
• Typical Hold-up Volume: <100µL: The low hold-up volume is important as it minimizes sample loss. This is particularly critical when working with precious or limited sample volumes, ensuring that the maximum amount of filtered sample is recovered.

Performance & Functionality

In terms of performance, the Pall Acrodisc Syringe Filters excel. The 0.2 µm PTFE membrane consistently delivered clear, particle-free solutions. I experienced excellent flow rates across various solvent types, a testament to the quality of the PTFE membrane and its pore structure. The HPLC certification was validated by the pristine chromatograms I obtained, with no discernible baseline noise attributable to filter extractables.

The primary strength of this product is its uncompromising chemical compatibility thanks to the PTFE membrane. I have yet to encounter a solvent that causes issues. The secure Luer lock connection is another significant functional advantage, preventing accidental disconnections during use. A minor weakness, inherent to all hydrophobic filters, is the need for pre-wetting when filtering aqueous solutions to ensure proper flow, though this is standard practice and not a fault of the filter itself.
