TN Lab Supply Heavy Wall Borosilicate 3.3 Glass 1000 ml Vacuum Filter Flasks Vacuum 1000 ml heavy wall borosilicate glass filter flask with side arm Also known as vacuum flasks or Büchner flasks Heavier walls than a standard conical flask to endure effects of vacuum filtration Sidearm with barbs extends 1 1/2" with a outside diameter increasing in size over the three rings from 0.45", 0.52" and the last ring at 0.55". This allows flexible hose solutions to a vacuum pump or system. High quality vacuum hose with 3/8" ID is perfect for attaching to the filter flask. However hosing that is stiff, not perfectly round, or not smooth inside, may require a 1/2" hose. During filtration, the filtrate enters and is held in the flask while the sample or residue remains on the filter paper in the Buchner Funnel, not included. The 1000ml 1 Liter Filter Flask is 9 1/2" tall. Can also be used as a vacuum trap in a vacuum line. Highly leach resistant to most chemicals Manufactured to ISO: 9001 Standards for Quality Assurance 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 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.
