DURAN® Filter Funnel, 1000 mL, Porosity 2

  • Manufactured from 3.3. expansion borosilicate glass
  • Funnels have an integral sintered glass filtration disc
  • Comprehensive range of funnel sizes and sinter porosities (grades) are available
  • The use of filter paper is not required
  • Resistant to most corrosive reagents including ammonia and concentrated sulphuric acid
  • Filter funnels can be used with a filtering flask via a conical rubber seal (GUKO)
  • Fired-on, highly durable white print
Product Overview
One of the most important separation methods in the laboratory environment is filtration, which is used to separate or clean different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. Büchner funnels are cylindrical with an integral sintered disc. Without additional filter paper, only coarse filtration is possible. Büchner funnels can also be used in vacuum filtration. The applied vacuum accelerates the filtration. Filter funnels are filters that are used for solid-liquid separation by means of vacuum.
