Polypropylene Membrane Filters, 0.45um, 142mm, Nonsterile, 25/Pk SKU: SF14887

Polypropylene (PP) Membrane Filters, 0.45µm, 142mm - SF14887

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polypropylene (PP) Membrane Filters, 0.45um, 142mm, Nonsterile, 25/Pk offers a robust solution for extending instrument life. 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

Hydrophobic

• Solvent Clarification - Polypropylene offers broad chemical resistance, making it suitable for filtering organic solvents
• Chemical Processing - Ideal for filtering acids, bases, and aggressive solvents that would degrade other membrane types
• Gas Filtration - Optimized for Hydrophobic PP membranes, which are excellent for venting applications and protecting vacuum pumps
• Prefiltration - The robust depth of PP media allows it to handle high particulate loads before final membrane filtration
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
• Quality Control Testing - Optimized for delivering reproducible results by removing particulates in standard pharmaceutical protocols
