Pall Magnetic Filter Funnel w/ Lid, 300mL, 47mm - 1/Pk - 4241

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. The funnel seats a flat membrane disc and seals it leak-free at the rim while drawing the sample through the seated membrane and resists common laboratory reagents. For the analyst, a consistent membrane seat turns each sample into a countable, weighable, reviewable result.

Key Characteristics

• 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
• Secure seal protects the membrane from twisting and tearing during setup
• Autoclavable construction supports aseptic technique between samples

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.

• Membrane Filtration Setup - The reusable funnel seats a membrane disc and drives the full sample through into a flask below.
• Water Microbiology - The funnel concentrates the sample onto a chosen membrane for colony counting in water quality programs.
• 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.
• High-Throughput Monitoring - Funnels pair with a manifold to filter many samples in parallel for routine microbial testing.
• Beverage QC Filtration - Apparatus funnels accept any compatible membrane disc for beverage microbiology screening tests.
