Pura Disc 13mm PTFE Syringe Filters, 0.2um, 100/Pk SKU: 6784-1302

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6784-1302

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 13mm, Syringe Filter, 0.2µm, nonsterile 100/pk offers validated bacterial retention for confident sample preparation. To achieve this medical-grade standard, the filter utilizes a Polytetrafluoroethylene (PTFE) membrane that provides a sharp 0.2 cutoff necessary for sterilizing biological fluids. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• 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 0.2 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

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• 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
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Analytical Sample Prep - Optimized to ensure data integrity by effectively filtering contaminants before instrumental analysis
• Environmental Monitoring - Ideal for filtering contaminants in water and wastewater analysis to ensure regulatory compliance
