Polypropylene (PP) Membrane Filters - SF18141
Engineered for high retention efficiency and superior chemical stability, the Tisch SF18141 achieves reliable separation results across a broad range of analytical and preparative applications. Underpinning this performance, precision-manufactured hydrophilic membrane with a verified 10.0 pore structure delivers consistent retention across the full operating range. With this in mind, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.
Material Specifications
- Low extractable levels and chemical inertness make polypropylene a reliable medium for filtering reagents prior to titration and spectroscopic analysis.
- Naturally hydrophobic, PP is well suited for air and gas venting applications where aqueous breakthrough must be prevented.
- Materials of construction maintain their mechanical and chemical properties at temperatures up to 80°C, supporting heated filtration protocols.
- 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.
Transitioning from qualitative screening to quantitative gravimetric analysis requires a membrane with documented tare weight consistency, and the manufacturing tolerances above ensure that your blank values remain within acceptable limits. Specifically, mechanical toughness allows you to operate at higher differential pressures without risking membrane failure, providing a safety margin for demanding applications. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
