Frequently asked questions

Find answers to common questions about our products and services

  • The exclusive filter-step internal design is a structural feature inside the funnel cone that promotes faster flow of liquids through filter media. By directing the liquid more efficiently, it reduces the time needed for filtration compared to smooth-walled funnels.

  • The external ribs create small air channels between the funnel and the neck of a receiving vessel, allowing air to escape as liquid flows in. This prevents a vacuum seal from forming — known as airlock — which would otherwise slow or stop liquid from draining through.

  • Yes, these polypropylene funnels are steam autoclavable at 121°C (250°F), making them suitable for applications that require sterilization between uses.

  • The parallel stem has an 8mm outer diameter (O.D.), so you would want to confirm that your receiving flask, tube, or adapter has an opening sized to accept an 8mm O.D. stem for a proper fit.

  • Polypropylene is a lightweight, durable plastic that withstands steam autoclaving at 121°C, making these funnels both reusable and sterilizable for laboratory workflows.
