Pall Magnetic Filter Funnel 150mL, 47mm - 1/Pk - 4247

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Funnel and base clamp the membrane so the whole sample passes through it while drawing the sample through the seated membrane and resists common laboratory reagents. Concentrating each sample onto a single membrane underpins the membrane filter technique behind regulated water and beverage microbiology.

Key Characteristics

• Secure seal protects the membrane from twisting and tearing during setup
• Autoclavable construction supports aseptic technique between samples
• Durable, chemically resistant body stands up to repeated reuse
• Seats and seals a flat membrane disc for leak-free dead-end filtration
• Connects to a side-arm vacuum flask or filtration manifold

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

Sterility

Nonsterile

• Particulate Determination - The funnel routes the full sample through a seated membrane to capture particulates for analysis.
• High-Throughput Monitoring - Funnels pair with a manifold to filter many samples in parallel for routine microbial testing.
• Water Microbiology - The funnel concentrates the sample onto a chosen membrane for colony counting in water quality programs.
• Membrane Filtration Setup - The reusable funnel seats a membrane disc and drives the full sample through into a flask below.
• Beverage QC Filtration - Apparatus funnels accept any compatible membrane disc for beverage microbiology screening tests.
• Reusable Lab Filtration - Durable, autoclavable construction supports repeated membrane filtration with aseptic technique.
