Pall SKU: FMFNL1050

Pall Filter Funnel w/ Polycarbonate Membrane, 100mL - 50/Pk - FMFNL1050

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Track-etched polycarbonate holds precise cylindrical pores for a sharp size cutoff while preserving captured particles and analytes and presents captured particles for direct examination. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• Smooth surface holds retained particles on top for microscopy and imaging
• Low protein binding preserves captured particles and analytes
• Track-etched polycarbonate gives precise cylindrical pores for a sharp cutoff
• Thin, flat film supports clean particle-size analysis
• Supplied sterile for immediate aseptic use

Confidence in your microbial results starts with capturing the organisms from your whole sample onto a single membrane. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible from your sample collection through enumeration.

• Particle Microscopy - Track-etched polycarbonate holds captured particles on a smooth surface for direct microscopic review.
• Cleanliness Analysis - Polycarbonate captures particulates on its flat face for counting and sizing under the microscope.
• Cell Surface Capture - The smooth membrane holds cells on top for imaging without embedding them in a fibrous depth matrix.
• Low-Binding Capture - Low adsorption preserves captured particles and analytes for accurate downstream counting and review.
• SEM Sample Preparation - Flat polycarbonate presents retained particles cleanly for scanning electron microscopy imaging.
• Precise Size Cutoff - Uniform cylindrical pores give a sharp, repeatable particle-size cutoff for defined retention studies.
