Whatman
Pura Disc 25mm Nylon Syringe Filters, 0.2um, 200 Pk SKU: 6751-2502

Nylon (NY) Syringe Filters, 0.2µm, 25mm - 6751-2502

Eliminate the risk of microbial contamination in your upstream workflows with the Nylon Whatman Puradisc, 25mm, Syringe Filter, 0.2µm 200/pk, optimized for sterile filtration protocols. Leveraging the specific retention properties of Nylon, this device offers a validated 0.2 barrier against microbial contaminants. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

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

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.
