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

    • 250 ml Filter flask apparatus is used primarily as a flask to draw a vacuum to enhance the rate of filtration when using a Buchner funnel
    • 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.
