Multiple Vacuum Filteration Apparatus, Stainless Steel Filter Funnel (1)
Whatman SKU: 10498761

Whatman Stainless Steel Filter Funnel - 1/Pk - 10498761

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Each funnel concentrates the organisms and particulates a sample carries onto the membrane face, leaving them ready to lift onto a plate or balance. Robust construction holds up to autoclaving between samples while holding the membrane edge to prevent sample bypass and routes the full sample through the membrane into the collection vessel. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

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

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.

• 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.
• 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.
• 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.
