Pall Glass Filter Funnel 1L, 47mm - 1/Pk - 4015-N

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Filter funnels seat a membrane disc across the base of the funnel so a full sample passes through in one contained step. Robust construction holds up to autoclaving between samples while connecting to a vacuum flask or manifold and clamps the membrane so the whole sample passes through it. Across routine monitoring programs, that clean separation supports defensible colony counts and traceable particulate determinations.

Key Characteristics

• Durable, chemically resistant body stands up to repeated reuse
• Seats and seals a flat membrane disc for leak-free dead-end filtration
• Autoclavable construction supports aseptic technique between samples
• Secure seal protects the membrane from twisting and tearing during setup
• 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. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on. Connect with our customer support technicians for chemical compatibility guidance and the right filtration product for your workflow.

• 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.
• Beverage QC Filtration - Apparatus funnels accept any compatible membrane disc for beverage microbiology screening tests.
• 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.
• Reusable Lab Filtration - Durable, autoclavable construction supports repeated membrane filtration with aseptic technique.
