1However, beakers are not the primary choice for measuring in labs, as they are only capable of providing figures within a 10 percent accuracy range. Dr. Anne Marie Helmenstine for About.com explains that the flat bottoms on beakers make them convenient tools to place on hot plates without falling over.a) 3 test tubes were labelled control, bag and beaker. b) 2 ml of water was added to the control test tube. 2 ml of the bag solution was added to the bag test tube and 2 ml of the beaker solution was added to the beaker test tube. c) 2 ml of Benedict’s reagent was added to each test tube and was suspended in a boiling water bath for 10 minutes. 1999 porsche 911 ls swapThe correct volume will be dispensed from the pipette if the side of the tip is touched to the inside wall of the flask (or beaker). Third kind of precise volumetric glass is burette. Burette is used to add titrant to the titrated solution and it has a scale on the side, so that you can precisely measure volume of the added solution. Vsim li na chen part 1
