Acro Disc Syringe Filters w/ Nylon Membrane - 0.45um, 25mm, 1000/Pk SKU: 4502

Nylon (NY) Syringe Filters, 0.45µm, 25mm - 4502

Reducing background noise in analytical assays begins with proper clarification, and the Nylon Syringe Filters is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Nylon membrane providing a consistent 0.45 cutoff that passes only your target analyte. 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 Nylon Membrane Characteristics

• Nylon membrane with hydrophilic affinity
• High Protein Binding characteristics
• Excellent resistance to esters, bases, and alcohols
• Avoid with strong acids (pH < 3) or protein samples (high binding)
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Luer Slip for secure fitting
• 3.9cm² effective filtration area
• < 125 µl holdup volume to minimize sample loss

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. 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.
