Polypropylene Membrane Filters, 0.45um, 47mm, Nonsterile, 200/Pk SKU: SF14554

Polypropylene (PP) Membrane Filters, 0.45µm, 47mm - SF14554

Reducing background noise in analytical assays begins with proper clarification, and the Polypropylene (PP) Membrane Filters, 0.45um, 47mm, Nonsterile, 200/Pk is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Polypropylene (PP) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Polypropylene (PP) Membrane Characteristics

• Polypropylene (PP) membrane with hydrophobic affinity
• Low Binding characteristics
• Broad chemical compatibility with organic solvents
• Requires pre-wetting for aqueous solutions
• 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. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
