Nitrocellulose Membrane Analytical Funnels, 0.2um, 47mm, 100mL, White/Black Grid, Sterile, 50/Pk
GVS SKU: 10497510

Featuring a removable hydrophilic nitrocellulose (NC) membrane housed in a measured 100 mL filtering unit, these single-use analytical funnels deliver a complete, ready-to-use system for liquid sample preparation. The 0.2 um rated, 47 mm membrane carries a white surface with a black printed grid for clear colony counting, and the all-in-one design pairs the funnel, base, pad, membrane, removable lid, and plug into one pre-sterilized assembly. After filtration, the membrane can be removed and transferred to a Petri dish for incubation and culturing.

Key Nitrocellulose Membrane Characteristics

• Hydrophilic nitrocellulose (NC) media for aqueous microbiological sample filtration
• 0.2 um rated pore size for retention of microorganisms in liquid samples
• White membrane with a black printed grid that aids visual colony counting and identification
• Removable design allows transfer of the membrane to agar plates and culturing devices
• Supports a wide range of qualitative and quantitative biological analysis after filtration

Key Construction Characteristics

• Single-use, pre-sterilized 100 mL filtering and culturing unit consisting of a measured filter funnel, base, pad, membrane, removable lid, and plug
• 47 mm membrane format with white/black grid surface
• Sterile and individually bagged, supplied 50 per pack
• Converts from a filtration unit into a Petri dish that can be labeled and incubated

This ready-to-use format eliminates the need to flame or sterilize funnels between samples, helping reduce preparation time and the risk of cross-contamination. The all-in-one construction supports reproducible results and protects sample integrity throughout filtration and culturing. Each unit is suited for monitoring contaminants across a broad range of liquid samples, from raw materials to finished products.
