Pura Disc 13mm PTFE Syringe Filters, 5.0um, 100/Pk SKU: 6784-1350

Polytetrafluoroethylene (PTFE) Syringe Filters, 5.0µm, 13mm - 6784-1350

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 13mm, Syringe Filter, 5.0µm, nonsterile 100/pk offers a robust solution for extending instrument life. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 5.0 rating remains consistent even under pressure. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

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 5.0 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

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. 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

• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• 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
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Research & Development - Supports protocols that need to clear gross precipitates, providing the ability to protect upstream systems
• Analytical Sample Prep - Ensures data integrity by effectively clearing gross precipitates before instrumental analysis
