Frequently asked questions

Find answers to common questions about our products and services

  • No — these funnels are specifically designed for non-vacuum, high-speed filtration. The internal helicoid ribs accelerate flow passively, and the vertical outer ribs prevent airlock, so no pump or vacuum setup is needed.

  • Internal helicoid (spiral) ribs channel liquid to increase filtration speed, while vertical ribs on the outside of the funnel prevent airlock — a common cause of slow or stalled gravity filtration in conventional funnels.

  • Yes — the polymethylpentene (PMP) construction makes these funnels unaffected by corrosive liquids, making them suitable for a wide range of chemical filtration applications.

  • Yes, the funnels are made from autoclavable polymethylpentene plastic, so they can be sterilized in a standard laboratory autoclave between uses.

  • These funnels are heat resistant up to 177°C (350°F), which covers standard autoclave cycles as well as use with elevated-temperature filtrations.

  • They are made from polymethylpentene (PMP), a plastic that is glass-clear for easy visual monitoring of filtrate, yet far more impact-resistant than glass and unaffected by corrosive liquids — offering a practical, durable alternative to traditional glass filter funnels.
