Pall Glass Filter Funnel 300mL, 47mm - 1/Pk - 4014-N

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. 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 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

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

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• 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.
• 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.
• Reusable Lab Filtration - Durable, autoclavable construction supports repeated membrane filtration with aseptic technique.
• Membrane Filtration Setup - The reusable funnel seats a membrane disc and drives the full sample through into a flask below.
