47mm Pressure Filteration Funnel, Stainless Steel, 1/Pk
Pall SKU: 4280

Pall Pressure Filtration Funnel 47mm - 1/Pk - 4280

Pall applies its proprietary membrane casting technology, producing precision-rated media for reproducible organism recovery and particulate retention. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Durable, chemically resistant construction stands up to repeated reuse while seating a flat membrane disc with a leak-free seal and connects to a vacuum flask or manifold to drive filtration. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• 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
• Connects to a side-arm vacuum flask or filtration manifold
• Seats and seals a flat membrane disc for leak-free dead-end filtration

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.

Nonsterile

• Membrane Filtration Setup - The reusable funnel seats a membrane disc and drives the full sample through into a flask below.
• Beverage QC Filtration - Apparatus funnels accept any compatible membrane disc for beverage microbiology screening tests.
• Water Microbiology - The funnel concentrates the sample onto a chosen membrane for colony counting in water quality programs.
• 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.
