Filtering Funnels



Filtering funnels have a cylinder that is separated from the funnel by a perforated plate or a fritted glass disc. Also known as Buchner funnels or Hirsch funnels, filtering funnels use vacuum suction that pulls the liquid through the filter into the cylinder. Eliminate the need to clean sintered glass filters with mineral acids using these disposable filtering funnels. They are economical, easy to use, and allow you to work without contamination risks for your filtrate. Available in various sizes, you can use these cost-effective filtering funnels more than once or dispose of them after each use.
