Polypropylene Membrane Filters, 0.2um, 125mm, Nonsterile, 25/Pk SKU: SF14878

Polypropylene (PP) Membrane Filters, 0.2µm, 125mm - SF14878

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Polypropylene (PP) Membrane Filters, 0.2um, 125mm, Nonsterile, 25/Pk is engineered to deliver sterile effluents with every use. Leveraging the specific retention properties of Polypropylene (PP), this device offers a validated 0.2 barrier against microbial contaminants. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. 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 0.2 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. 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.
