47mm Filter Funnels, Glass Filter Funnel w/ Accs. (300mL Funnel w/ 1L Flask), 1/Pk
Pall SKU: 4013

Pall Glass Filter Funnel (300mL Funnel with 1L flask), 47mm - 1/Pk - 4013

Pall Corporation brings decades of membrane filtration expertise to water, beverage, and pharmaceutical microbiology workflows. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. Applied pressure differential draws the sample through the seated membrane while resisting common laboratory reagents and clamps the membrane so the whole sample passes through it. 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
• Connects to a side-arm vacuum flask or filtration manifold
• Autoclavable construction supports aseptic technique between samples
• 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.

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