Advantec 311401 Holder Parts 300mL FUNNEL, KG47

This funnel is designed for vacuum filtration systems using 47 mm membrane filters, allowing users to process liquid samples efficiently. It is commonly used in microbiological testing, particulate analysis, and general laboratory filtration workflows.

This funnel is suitable for a wide range of lab applications such as DNA/RNA filtration, protein analysis, sterility testing, colony counting, and solvent purification. Its design supports both analytical and microbiological workflows.

The funnel is typically made from durable, chemically resistant materials (such as polysulfone or borosilicate glass depending on the system) and includes features like a recessed filter support to prevent membrane damage. It also allows aseptic venting using syringe filters, improving safety and contamination control.

A 300 mL capacity provides a balance between throughput and control, making it ideal for small to medium sample volumes. It reduces the need for repeated pours while maintaining precise filtration, improving efficiency in routine laboratory work.

The KG47 funnel is specifically made for Advantec 47 mm filter holder assemblies, including polysulfone and glass microanalysis holders. It integrates easily with vacuum flasks and filtration manifolds, making it a versatile replacement or upgrade component.
