Pall MicroFunnel Filter Funnel w/ Polycarbonate Membrane, 0.4um, 300mL - 20/Pk - FMFNL3020
Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Low-binding polycarbonate preserves captured particles and analytes while presenting captured particles for direct examination and holds precise cylindrical pores for a sharp size cutoff. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.
Key Characteristics
- Smooth surface holds retained particles on top for microscopy and imaging
- Low protein binding preserves captured particles and analytes
- Supplied sterile for immediate aseptic use
- Thin, flat film supports clean particle-size analysis
- Track-etched polycarbonate gives precise cylindrical pores for a sharp cutoff
Accurate microbial counts depend on concentrating the whole sample onto one clean membrane surface. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible so each result you release holds up to review.
