Pura Disc 13mm H-PTFE Syringe Filters 0.45um, Hydrophilic, 500 Pk SKU: 6773-1304

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6773-1304

In high-throughput analytical laboratories, the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.45µm, 500/pk series establishes a standard for effective particulate removal and sample clarification. To ensure analytical precision, the unit is constructed with a high-grade Hydrophilic Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Key Hydrophilic Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophilic Polytetrafluoroethylene (PTFE) membrane treated for hydrophilic affinity
• Low Protein Binding characteristics
• Extreme chemical resistance to aggressive solvents, acids, and bases
• Hydrophobic version acts as an effective moisture barrier
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 1.3cm² effective filtration area
• <25µl holdup volume to minimize sample loss

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
• Research & Development - Supports protocols that need to remove particulates, providing the ability to protect analytical instruments
