Filtering Funnels

Disposal, Economical, and Easy to Use

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, each uses vacuum suction that pulls liquid through the filter into the cylinder.

Work without risk for your filtrate and eliminate the need to clean sintered glass filters with mineral acids using these disposable filtering funnels. Available in various sizes, you can use these cost-effective filtering funnels more than once or dispose of them after each use.
