2 Beaker Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. Beakers are NOT accurate measuring devices. The numbers on the side of the beaker provides an estimation. They are not to be used to measure exact volume. There are several different sizes of beakers in the side cubbard.
3 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.
4 Graduated Cylinder A graduated cylinder is used to measure volumes of liquids.
5 Test Tubes 13 x 100 mm test tubes Ignition tube 10 x 75 mm test tubes
6 Test Tube Holder A test tube holder is useful for holding a test tube which is too hot to handle.
7 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 Brushes
8 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.
9 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. These are not located in lab drawers or side cabinets, they will be given to you when needed.
10 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.
11 Watch Glass A watch glass is used to hold a small amount of solid, such as the product of a reaction.
12 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.
13 Stirring rod with rubber policeman The rubber policeman is used like a spatula is used in the kitchen. It is used to get out solids formed in chemical reactions called a precipitate.
14 Litmus Paper Red litmus paper is used to identify bases. Blue litmus paper is used to identify acids.
15 Forceps Forceps (or tweezers) are used to pick up small objects.
16 Funnel A funnel is used to aid in the transfer of liquid from one vessel to another.
17 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.
18 Weighing Boat Weighing boats are used to weigh solids that will be transferred to another vessel.
19 Beaker Tongs Beaker tongs are used to move beakers containing hot liquids
20 Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids.
21 Evaporating Dish The evaporating dish is used for the heating of stable solid compounds and elements.
22 Crucible Crucibles are used for heating certain solids, particularly metals, to very high temperatures. These are too fragile to keep in lab stations.
23 Clay Triangle The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner.
24 Crucible Tongs For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers!
25 Ringstands and their Components Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.
26 Ringstands and their Components Iron Rings Iron rings connect to a ringstand and provide a stable, elevated platform for the reaction.
27 Ringstands and their Components Utility Clamps Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand.
28 Ringstands and their Components Wire 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!
29 Scoopula used to get solids out of reagent jars.
30 Strikers (Friction Lighter) Strikers are used to light Bunsen burners. The flints on strikers are expensive. Do not operate the striker repeatedly just to see the sparks!
31 Hot Hands Used to protect your hands from hot equipment.
32 Triple beam balance Balance
33 Lab Tray The lab tray is at the lab station by the wall.
