Funnel, Analytical, Polypropylene, 180mm MINIMUM OF 5 CASES

The precise 60° cone angle is the standard geometry required to properly seat folded filter paper, ensuring full contact between the paper and funnel wall. This promotes rapid, even flow of liquid through the filter rather than allowing it to pool or bypass the paper.

The ribbing creates small channels between the filter paper and the funnel wall, allowing air to escape as liquid drains. Without this venting, a vacuum (air lock) can form and slow or stop filtration entirely — the ribbing keeps flow continuous and efficient.

Yes, this 180mm funnel is designed to accommodate standard filter paper sizes, so commonly available quantitative and qualitative filter papers cut or supplied in matching diameters will fit without modification.

Yes, these polypropylene analytical funnels are approved for use with food products, making them suitable for food science, quality control, or food preparation applications in addition to standard analytical chemistry use.

Polypropylene is a heavy-duty, chemically resistant plastic that resists many common laboratory reagents and will not shatter if dropped. It is a practical choice for routine analytical work where durability and break resistance are priorities.

No — this funnel is available in 9 different sizes, so if 180mm does not match your filter paper or vessel requirements, other sizes in the same series should be available to suit your application.
