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.
