Pall Magnetic Filter Funnel 500mL, 47mm - 1/Pk - 4238

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. 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 routing the full sample through the membrane below and holds up to autoclaving between samples. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

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

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.

Nonsterile

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