1000 ml Erlenmeyer Conical Filter Flask Applications:

• 1000 ml Filter flask 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 are being carried though a vacuum line
• 1000 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.
