Sterile Polytetrafluoroethylene (PTFE) Hydrophilic Syringe Filters
Manufacturer: The Lab Depot
The Sterile Hydrophilic PTFE Syringe Filters from The Lab Depot are the premier choice for laboratories handling aggressive solvents, acids, and bases that would typically degrade other membrane materials. While PTFE is naturally hydrophobic, these filters are treated to be hydrophilic, allowing for the effortless filtration of both aqueous and organic solutions without the need for manual pre-wetting. Each filter is HPLC Certified and housed in high-purity virgin polypropylene, ultrasonically bonded to ensure a leakproof seal even under high back-pressure. These units are individually wrapped and gamma sterilized, making them ideal for pharmaceutical, clinical, and high-sensitivity analytical applications where contamination is not an option.
Description
Available in the two most common laboratory diameters and pore sizes to optimize flow rate versus particle retention.
Features:
- Universal Solvent Compatibility: PTFE is virtually inert, making these filters the "gold standard" for filtering harsh HPLC solvents and degassing chromatography mobile phases
- Low Hold-up Volume: The unique concentric funnel-shaped barrel is designed to maximize sample recovery, which is critical when working with expensive or limited sample volumes
- Hydrophilic Convenience: Unlike standard PTFE, these require no alcohol pre-wetting for aqueous samples, saving time and reducing the risk of solvent-induced sample precipitation
- High-Pressure Reliability: Ultrasonic bonding ensures the housing remains intact under pressure, while the inscribed barrel clearly identifies the filter media type to prevent laboratory errors
Analytical Application Insights:
- Pore Size Selection: Use the 0.22 µm filters for sterile filtration or UHPLC applications where maximum particle removal is required. The 0.45 µm filters are ideal for standard HPLC and general clarification of viscous organic samples.
- HPLC Integrity: These filters are certified to have extremely low levels of UV-absorbing extractables, ensuring they do not introduce "ghost peaks" into your chromatography results.
- Syringe Connection: The Luer-Lok inlet provides a secure, threaded connection that prevents the filter from "popping off" during the filtration of viscous samples.
