Erlenmeyer Flask : Erlenmeyer Flask Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated. Florence Flask : Florence Flask Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure. Graduated Cylinder : Graduated Cylinder A graduated cylinder is used to measure volumes of liquids. Gas Collecting Bottle : Gas Collecting Bottle We use gas collecting bottles when large volumes of gases are produced, and must be collected by the displacement of water. Test Tubes : Test Tubes 13 x 100 mm test tubes 10 x 75 mm test tubes Ignition tube Test Tube Holder : Test Tube Holder A test tube holder is useful for holding a test tube which is too hot to handle. Test Tube Brushes : Test Tube Brushes Test tube brushes are used to clean test tubes and graduated cylinders. Forcing a large brush into a small test tube will often break the tube. Test Tube Racks : Test Tube Racks Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes. Rubber Stoppers : Rubber Stoppers Rubber stoppers are used to close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place. Spot Plates : Spot Plates Spot plates are used when we want to perform many small scale reactions at one time. We will use these many times during the year. Watch Glass : Watch Glass A watch glass is used to hold a small amount of solid, such as the product of a reaction. Glass Stir Rod : Glass Stir Rod A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution. Medicine Dropper : Medicine Dropper A medicine dropper is used to transfer a small volume of liquid (less than one mL). On top of each medicine dropper is a “rubber bulb” Litmus Paper : Litmus Paper Red litmus paper is used to identify bases. Blue litmus paper is used to identify acids. Forceps : Forceps Forceps (or tweezers) are used to pick up small objects. Funnel : Funnel A funnel is used to aid in the transfer of liquid from one vessel to another. Mohr Pipet : Mohr Pipet A Mohr pipet measures and delivers exact volumes of liquids. Wash Bottle : Wash Bottle A wash bottle has a spout that delivers a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle. Weighing Boat : Weighing Boat Weighing boats are used to weigh solids that will be transferred to another vessel. Spatulas : Spatulas Spatulas are used to dispense solid chemicals from their containers. Chemicals should never be transferred with your bare hands. Beaker Tongs : Beaker Tongs Beaker tongs are used to move beakers containing hot liquids Bunsen Burner : Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids. Evaporating Dish : Evaporating Dish The evaporating dish is used for the heating of stable solid compounds and elements. Crucible : Crucible Crucibles are used for heating certain solids, particularly metals, to very high temperatures. Clay Triangle : Clay Triangle The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner. Crucible Tongs : Crucible Tongs For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers! Glass Plates : Glass Plates Glass plates provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases. Triangular File : Triangular File Triangular files are used primarily to cut glass rod, a skill that your instructor will share with you when it becomes useful. Ringstands and their Components : Ringstands and their Components Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner. Ringstands and their ComponentsIron Rings : Ringstands and their ComponentsIron Rings Iron rings connect to a ringstand and provide a stable, elevated platform for the reaction. Ringstands and their ComponentsUtility Clamps : Ringstands and their ComponentsUtility Clamps Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand. Ringstands and their ComponentsDouble Buret Clamps : Ringstands and their ComponentsDouble Buret Clamps Double Buret clamps are used to burets – long graduated tubes used in titration. Ringstands and their ComponentsWire Gauze : Ringstands and their ComponentsWire Gauze Wire gauze sits on the iron ring to provide a place to stand a beaker. On older wire gauze, the white material is asbestos! Pressed Fiber Pad : Pressed Fiber Pad A 4” x 4” square of ceramic fiber, it provides a surface for hot beakers so that the beaker does not come in contact with a cold countertop and shatter. Strikers : Strikers Strikers are used to light Bunsen burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!
