Pall SKU: 4011-N

Pall Glass Filter Funnel (300mL Funnel, no flask), 47mm - 1/Pk - 4011-N

Pall's engineering and quality infrastructure extends from the process-scale filtration systems it supports worldwide to its laboratory membrane filtration devices. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. Robust construction holds up to autoclaving between samples 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

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. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.

• 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.
• Reusable Lab Filtration - Durable, autoclavable construction supports repeated membrane filtration with aseptic technique.
