Hydrophilic PVDF Membrane Filters, 0.45um, 90mm, Nonsterile, 100/Pk SKU: SF18139

PVDF Membrane Filters, 0.45µm, 90mm - SF18139

For researchers requiring consistent baselines in HPLC and dissolution testing, the PVDF Hydrophilic Membrane Filters, 0.45um, 90mm, Nonsterile, 50/pk offers a robust solution for extending instrument life. At the core of the device is a uniform PVDF matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key PVDF Membrane Characteristics

• PVDF membrane with hydrophilic (hplc) / hydrophobic (venting) affinity
• Ultra-Low Protein Binding characteristics
• Excellent resistance to HPLC mobile phases, alcohols, and mild hydrocarbons
• Incompatible with acetone, DMSO, or strong bases (> pH 12)
• Verified 0.45 retention rating for clarification

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. 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.
