Whatman
Pura Disc 25mm Nylon Syringe Filters, 0.2um, 50 Pk SKU: 6750-2502

Nylon (NY) Syringe Filters, 0.2µm, 25mm - 6750-2502

When sample purity is non-negotiable, the Nylon Whatman Puradisc, 25mm, Syringe Filter, 0.2µm 50/pk serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. Leveraging the specific retention properties of Nylon, 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. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Nylon Membrane Characteristics

• Nylon membrane with hydrophilic affinity
• High Protein Binding characteristics
• Compatible with aqueous (non-acidic) solutions and most organic solvents
• High binding matrix: Avoid use with biological samples where yield is critical; incompatible with acidic solutions (pH < 3)
• Verified 0.2 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

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. 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.
