GVS EXTRACTO Vacuum Filtration Set, CA, 0.22µm, 250ml, Blue 12/pack EXVF0250BCA02AZS

A single-use, pre-sterilized analytical funnel designed for membrane filtration of liquid samples and subsequent culturing or quantitative analysis. The device integrates a 47 mm nitrocellulose membrane (0.45 µm pore size) with a white/black gridded surface and a measured 100 mL funnel assembly, supplied sterile and individually bagged for aseptic handling. It is intended for rapid preparation and filtration of samples for microbiological and particulate analysis in applications such as beverage, dairy, potable water, soft drink and wastewater testing.

Key Features:

• Diameter: 47 mm
• Membrane material: Nitrocellulose (NC)
• Pore size: 0.45 µm
• Grid: White/Black gridded membrane
• Funnel capacity: 100 mL
• Sterility: Sterile; individually bagged
• Pack quantity: 50 per box

Advantages:

• Ready-to-use, pre-sterilized single-use unit reduces cross-contamination and eliminates the need to sterilize funnels between samples.
• Gridded nitrocellulose membrane captures particles on the surface and facilitates easy colony counting and qualitative/quantitative analyses.
• All-in-one funnel-to-Petri-dish conversion allows filtered membranes to be labeled and incubated directly for culturing.
• Design avoids flaming and minimizes external handling errors, supporting reproducible results and faster testing workflows.
