Nitrocellulose Analytical Funnels, 0.2um, 47mm, 100mL, White/Black Grid, Sterile, 50/Pk
GVS SKU: 10497507

Featuring a removable 0.2um nitrocellulose membrane with a 47mm diameter and a white/black grid surface, these single-use, pre-sterilized analytical funnels deliver a complete 100mL filtration system for liquid sample preparation. Each unit consists of a measured filter funnel, base, pad, membrane, removable lid, and plug, ready to use straight from the package. After filtration, the membrane can be lifted and transferred to a Petri dish for a wide range of qualitative and quantitative biological analyses, eliminating the funnel and base sterilization steps between samples.

Key Nitrocellulose Membrane Characteristics

• Naturally hydrophilic nitrocellulose surface promotes uniform wetting and consistent sample flow.
• 0.2um pore size supports retention of bacteria and fine particulates for microbiological monitoring.
• Removable membrane format allows transfer to a Petri dish for culturing and colony counting.
• White membrane with a printed black grid provides clear contrast for accurate colony enumeration.

Key Construction Characteristics

• Single-use, pre-sterilized 100mL filtration unit with measured filter funnel, base, pad, removable lid, and plug.
• 47mm membrane diameter housed in a self-contained disposable funnel assembly.
• Sterile and ready to use, requiring no flaming or autoclaving between samples.
• Supplied 50 units per pack.

These funnels maintain sample integrity by combining filtration and culturing in one closed, disposable unit, virtually eliminating cross-contamination between funnel and membrane. The all-in-one design converts easily into a labeled, incubatable Petri dish, streamlining workflows and reducing preparation time. Ready-to-use sterility provides reliable, repeatable results across raw materials and finished products.
