Polypropylene/Polyethylene Separator Dp Filters, 10um, 25mm, 500/Pk SKU: 60343

Polypropylene (PP) Membrane Filters - 60343

Designed to deliver reproducibility and confidence across critical sample types, the Pall 60343 provides the filtration consistency that method validation demands. Furthermore, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. In turn, 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.
• Low extractable levels and chemical inertness make polypropylene a reliable medium for filtering reagents prior to titration and spectroscopic analysis.
• Depth-type PP configurations provide enhanced particle loading capacity for prefiltration in industrial chemical processing applications.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• Temperature rating of 107°C provides the thermal headroom required for warm sample processing, heated media preparation, and elevated-temperature analytical methods.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. Because polypropylene produces extremely low extractable levels in organic solvents, your filtrate remains analytically clean — protecting the detection limits and baseline stability your chromatographic methods require. 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.

• Depth Filtration Stack - Provides a lofty depth matrix in stacked disc filters, increasing the dirt-holding capacity for viscous fluid streams.
• Solvent Pre-cleaning - Removes gross contaminants from bulk solvents before they enter fine filtration loops, extending system maintenance cycles.
• Coarse Particulate Removal - Efficiently clears visible debris from environmental samples, preparing them for finer analytical filtration steps.
• 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.
