Polypropylene Membrane Filters, 0.1um, 25mm, Nonsterile, 100/Pk SKU: SF18055

Polypropylene (PP) Membrane Filters - SF18055

Engineered for high retention efficiency and superior chemical stability, the Tisch SF18055 achieves reliable separation results across a broad range of analytical and preparative applications. Supporting this capability, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. Precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Naturally hydrophobic, PP is well suited for air and gas venting applications where aqueous breakthrough must be prevented.
• Polypropylene (PP) membranes offer broad chemical resistance to organic solvents, strong acids, and concentrated bases.
• Depth-type PP configurations provide enhanced particle loading capacity for prefiltration in industrial chemical processing applications.
• Lightweight and mechanically flexible, polypropylene provides a cost-effective filtration medium for aggressive chemical environments.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 120°C, supporting heated filtration protocols.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. With this in mind, mechanical toughness allows you to operate at higher differential pressures without risking membrane failure, providing a safety margin for demanding applications. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophobic

• Polymer Analysis - Filters dissolved polymer solutions for gel permeation chromatography (GPC) without shearing high molecular weight chains.
• Clarification Pre-filter - Placed on top of final membrane filters in vacuum funnels to catch heavy sediment and prevent rapid clogging.
• Solvent Pre-cleaning - Removes gross contaminants from bulk solvents before they enter fine filtration loops, extending system maintenance cycles.
• Hot Solvent Filtration - Withstands elevated temperatures during the filtration of hot saturated solutions in recrystallization protocols.
• Chemical Resis. Testing - Used as a test coupon to verify material compatibility with new synthetic fluids before scaling up production runs.
• Depth Filtration Stack - Provides a lofty depth matrix in stacked disc filters, increasing the dirt-holding capacity for viscous fluid streams.
