Polypropylene Membrane Filters, 0.2um, 142mm, Nonsterile, 25/Pk SKU: SF14886

Polypropylene (PP) Membrane Filters, 0.2µm, 142mm - SF14886

Ensuring the biological integrity of sensitive media begins with reliable filtration, and the Polypropylene (PP) Membrane Filters, 0.2um, 142mm, Nonsterile, 25/Pk is engineered to deliver sterile effluents with every use. To achieve this medical-grade standard, the filter utilizes a Polypropylene (PP) membrane that provides a sharp 0.2 cutoff necessary for sterilizing biological fluids. 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

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.

Hydrophobic

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