Whatman
Pura Disc 13mm PTFE Syringe Filters, 0.2um, 2000 Pk SKU: 6766-1302

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6766-1302

Eliminate the risk of microbial contamination in your upstream workflows with the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 13mm, Syringe Filter, 0.2µm, nonsterile (2000 pcs), optimized for sterile filtration protocols. Leveraging the specific retention properties of Polytetrafluoroethylene (PTFE), this device offers a validated 0.2 barrier against microbial contaminants. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. 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 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. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. 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.

• 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
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
• Research & Development - Supports protocols that need to filter contaminants, providing the ability to optimize sample clarity
