Polypropylene Membrane Filters, 0.45um, 125mm, Nonsterile, 25/Pk SKU: SF14879

Polypropylene (PP) Membrane Filters, 0.45µm, 125mm - SF14879

Reducing background noise in analytical assays begins with proper clarification, and the Polypropylene (PP) Membrane Filters, 0.45um, 125mm, Nonsterile, 25/Pk is engineered to remove interfering solids efficiently. Facilitating rapid sample turnover, the hydrophobic Polypropylene (PP) membrane structure ensures the 0.45 rating remains consistent even under pressure. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

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

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
