• Metal Clamp to hold Buchner funnel to solid to filter flask
• Ground glass fittings on both glass frit filter base and filter flask for vacuum tight fitting
• Glass frit suitable for paper or plastic filter media to seal between 300 ml funnel and glass frit
• Manufactured to ISO: 9001 Standards for Quality Assurance
• CE Certification to assure complete compliance with standards during manufacture
• Other sizes available: 500 ml, 1000 ml

• Glass 250 ml Glass Filter Apparatus with Conical Erlenmeyer Filter Flask and Glass Frit Funnel Applications

  • 250 ml Filter flask apparatus is used primarily as a flask to draw a vacuum to enhance the rate of filtration
  • The side arm is attached to a vacuum source such as a vacuum pump or aspirator.
  • Filter flasks are also used a separating flask in a vacuum line to remove liquids that to prevent being carried though a vacuum line
  • 250 ml Conical Filter Flasks are also used with other types of filter that may utilize either a paper or other types of frit such as glass or plastic
  • The vacuum being applied increased the draw through a filter membrane to nearly an atmosphere of pressure  if the vacuum level is low enough.
  • The glass frit is reusable and often used with paper or other removable disk filters
  • The clamp is used as both a mechanism to hold the 300 ml funnel in place during filtration and to permit easy change of filter media and retrieval of the solids captured on the filter media.
  • The filter may be used in gravimetric applications where the filter media may be dried and weighed to determine the weight of solids collected in a given liquid volume or process.
