Polypropylene Membrane Filters, 0.45um, 25mm, Nonsterile, 200/Pk SKU: SF14552

Polypropylene (PP) Membrane Filters, 0.45µm, 25mm - SF14552

In high-throughput analytical laboratories, the Polypropylene (PP) Membrane Filters, 0.45um, 25mm, Nonsterile, 200/Pk series establishes a standard for effective particulate removal and sample clarification. Driving this clarification performance is a hydrophobic Polypropylene (PP) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

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

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. Trust in the consistent performance of your filtration step to remove the variables that often lead to costly re-runs and ambiguous data. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
