Stainless Steel (304) Filter Funnel, 1000mL, 47mm, 1/Pk
Pall SKU: 4230

Pall Stainless Steel Filter Funnel 1000mL, 47mm - 1/Pk - 4230

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. Built around a membrane held at its base, the funnel routes the whole sample across that membrane and into the flask below. A secure seal holds the membrane edge to prevent sample bypass while drawing the sample through the seated membrane and stands up to repeated reuse and cleaning. 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
• Durable, chemically resistant body stands up to repeated reuse
• Autoclavable construction supports aseptic technique between samples
• Seats and seals a flat membrane disc for leak-free dead-end filtration
• Secure seal protects the membrane from twisting and tearing during setup

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

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