Acro Disc PSF Syringe Filters w/ Nylon Membrane - GxF/0.45um, 200/Pk SKU: AP-4549

Nylon (NY) Syringe Filters, 0.45µm, 25mm - AP-4549

For researchers requiring consistent baselines in HPLC and dissolution testing, the Nylon Syringe Filters offers a robust solution for extending instrument life. 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. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. 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
• 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

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. 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.
