Pura Disc 25mm Nylon Syringe Filters, 0.45um, 200 Pk SKU: 6751-2504

Nylon (NY) Syringe Filters, 0.45µm, 25mm - 6751-2504

Reducing background noise in analytical assays begins with proper clarification, and the Nylon Whatman Puradisc, 25mm, Syringe Filter, 0.45µm 200/pk is engineered to remove interfering solids efficiently. Driving this clarification performance is a hydrophilic Nylon membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. 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 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
• 4.2cm² 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
