47mm Filter Funnels, Glass Filter Funnel w/ Accs. (1L Funnel w/ 4L Flask), 1/Pk
Pall SKU: 4012-N

Pall Glass Filter Funnel (1L Funnel with 4L flask), 47mm - 1/Pk - 4012-N

Pall Corporation produces under ISO quality system controls, with membranes verified for the rated retention that microbiological and gravimetric analysis depend on. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. The funnel seats a flat membrane disc and seals it leak-free at the rim and resists common laboratory reagents. 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
• Durable, chemically resistant body stands up to repeated reuse
• Secure seal protects the membrane from twisting and tearing during setup
• Autoclavable construction supports aseptic technique between samples

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on.

• 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.
• 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.
• Particulate Determination - The funnel routes the full sample through a seated membrane to capture particulates for analysis.
