Pura Disc 13mm H-PTFE Syringe Filters 0.45um, Hydrophilic, 100/Pk SKU: 6772-1304

Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6772-1304

For researchers requiring consistent baselines in HPLC and dissolution testing, the Hydrophilic Polytetrafluoroethylene (PTFE) Whatman Puradisc™ Syringe Filter, 13mm, 0.45µm, 100/pk offers a robust solution for extending instrument life. 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. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Hydrophilic Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophilic Polytetrafluoroethylene (PTFE) membrane with hydrophobic (requires pre-wetting) or hydrophilic (if treated) 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

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• 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
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Sample Clarification - Protecting analytical instruments via rapidly removing particulates to maintain high throughput in busy laboratories
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
