Whatman
GD/X 25mm Syringe Filter, Nylon Filteration Medium, 0.45um (150 pcs) SKU: 6870-2504

Nylon (NY) Syringe Filters, 0.45µm, 25mm - 6870-2504

Designed to protect sensitive chromatography columns from clogging, the Nylon Whatman GD/X 25mm Syringe Filter, nylon filtrationmedium, 0.45µm, 150/pk delivers exceptional retention of particulates without compromising flow rates. At the core of the device is a uniform Nylon 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. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

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 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 4.6cm² effective filtration area
• 1400 µL 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. Protecting your downstream processes requires a defensive strategy, and utilizing these verified filters gives you the peace of mind that your work is safe. 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.
