Whatman
Pura Disc 13mm PTFE Syringe Filters, 0.2um, 500 Pk SKU: 6783-1302

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 13mm - 6783-1302

Eliminate the risk of microbial contamination in your upstream workflows with the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 13mm, Syringe Filter, 0.2µm, nonsterile 500/pk, optimized for sterile filtration protocols. Central to this performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. 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

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. 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
• 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
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
