What glassware fits the rubber stopper?
Rubber bungs are often used with glass containers such as test tubes, flasks, jugs, and many other pieces of standard lab equipment.
What is a stopper in a flask?
Chemists frequently use rubber stoppers in their labs to plug flasks and test tubes. The purpose of these stoppers is to prevent liquids, and sometimes gases, from escaping their containers, as well as prevent contaminants from entering the containers.
Which flask is used for filtration?
A Büchner flask, also known as a vacuum flask, filter flask, suction flask, side-arm flask, Kitasato flask or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.
What is the side-arm of a filter flask for?
Side-Arm Flasks The side-arm flask looks like an Erlenmeyer flask with a short arm coming out of it. The arm is designed to connect the flask to a vacuum source. When sealed on the top with a stopper or a Buchner funnel, the vacuum flask will hold a reduced pressure.
What does a rubber stopper look like?
Shape. The standard stopper is cylindrical in shape, with a tapered bottom end. Some rubber stoppers contain one or two holes to allow the insertion of pipettes, tubing or test equipment (e.g., a thermometer).
How do you set up vacuum filtration?
To perform a vacuum filtration, clamp the flask securely to a ring stand. Add a Buchner funnel with a rubber funnel adaptor. Obtain a piece of filter paper in the funnel that is small enough to remain flat but large enough to cover all of the holes in the filter.
How do you use a vacuum filter flask?
Suction Filtration Summary Connect thick-walled hosing from the side arm to a vacuum trap and the water aspirator. Place a vacuum sleeve on the Buchner (or Hirsch) funnel, then filter paper on the funnel so it arches downward. Turn on the aspirator. Add a few mL of the same solvent used in the flask to wet the filter.
