Polypropylene Membrane Filters, 0.1um, 90mm, Nonsterile, 25/Pk SKU: SF18057

Polypropylene (PP) Membrane Filters - SF18057

Engineered for high retention efficiency and superior chemical stability, the Tisch SF18057 achieves reliable separation results across a broad range of analytical and preparative applications. Additionally, verified 0.1 pore distribution across the hydrophobic membrane surface guarantees batch-to-batch consistency in particle capture and analyte passage. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Polypropylene (PP) membranes offer broad chemical resistance to organic solvents, strong acids, and concentrated bases.
• Lightweight and mechanically flexible, polypropylene provides a cost-effective filtration medium for aggressive chemical environments.
• Full pH spectrum durability allows PP membranes to maintain structural integrity in both strongly acidic and strongly alkaline process streams.
• Depth-type PP configurations provide enhanced particle loading capacity for prefiltration in industrial chemical processing applications.
• Low extractable levels and chemical inertness make polypropylene a reliable medium for filtering reagents prior to titration and spectroscopic analysis.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. Hydrophobic PP naturally vents aqueous liquids while passing gases and organic vapors, making it well suited for gas filtration and solvent venting applications. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Backflush Regeneration - Durable enough to withstand back-flushing cycles in reusable filter holders, reducing consumable waste and costs.
• Clarification Pre-filter - Placed on top of final membrane filters in vacuum funnels to catch heavy sediment and prevent rapid clogging.
• Chemical Resis. Testing - Used as a test coupon to verify material compatibility with new synthetic fluids before scaling up production runs.
• Hot Solvent Filtration - Withstands elevated temperatures during the filtration of hot saturated solutions in recrystallization protocols.
• Depth Filtration Stack - Provides a lofty depth matrix in stacked disc filters, increasing the dirt-holding capacity for viscous fluid streams.
• Coarse Particulate Removal - Efficiently clears visible debris from environmental samples, preparing them for finer analytical filtration steps.
