Whatman
Pura Disc 25mm PTFE Syringe Filters, 1.0um, 1000 Pk SKU: 6798-2510

Polytetrafluoroethylene (PTFE) Syringe Filters, 1.0µm, 25mm - 6798-2510

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 25mm, Syringe Filter, 1.0µm, nonsterile 1000/pk offers a robust solution for extending instrument life. At the core of the device is a uniform Polytetrafluoroethylene (PTFE) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

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 1.0 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 4.2cm² effective filtration area
• <100µl 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. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• 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
• Quality Control Testing - Delivers reproducible results by removing high particulate loads in standard pharmaceutical protocols
• Analytical Sample Prep - Ensures data integrity by effectively removing high particulate loads before instrumental analysis
