| bunsen burner | A Bunsen burner, named after Robert Bunsen, produces a single open gas flame, which is used for heating, sterilization, and combustion |
| ring stand | A ring stand is a piece of scientific equipment, clamps can be attached to hold other pieces of equipment such as burettes, test tubes and flasks. |
| pipestem triangle | A piece of laboratory equipment that is used to support a crucible being heated by a Bunsen burner or other heat source. |
| utility clamp | A piece of laboratory equipment that is used to hold rounded laboratory glassware, for example, a beaker, flask, etc. |
| iron ring | Iron rings are commonly used in chemistry laboratories for supporting apparatus above the work surface |
| evaporating dish | Used to evaporate excess solvents - most commonly water - to produce a concentrated solution or a solid precipitate of the dissolved substance. |
| mortar and pestle | Used to prepare ingredients or substances by crushing and grinding them into a fine paste or powder |
| test tubes | A test tube is a clear glass or plastic container that is used to hold, mix, and heat chemical experiments. |
| crucible and cover | Crucible are used in the laboratory to contain chemical compounds when heated to extremely high temperatures |
| beaker | A beaker is a simple "container" which is used for heating and stirring liquids in laborartories |
| safety goggles | duh |
| corks | duh |
| watch glass | used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker. |
| Erlenmeyer flask | A flask that has a flat bottom with a tapered neck. The mouth, or opening, is used for pouring solutions and may be closed with a stopper in order to store samples. |
| wire gauze | Wire gauze is used in combination with a Bunsen burner. It is a heat-resistant wire mesh on which beakers or other glassware are supported during heating |
| rubber stoppers | same as corks |
| buret | Used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end. |
| pipet | Used in chemistry, biology and medicine to transport a measured volume of liquid |
| thermometer | Determines temperature |
| graduated cylinder | A common piece of laboratory equipment used to measure volume |
| wash bottle | A squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks |
| micropipets | Same as pipet, but smaller |
| dropper | Used to transfer small quantities of liquids |
| test tube holder | Used for holding a test tube in place when the tube is hot or should not be touched |
| lab burner | same as Bunsen burner |
| forceps | Used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task |
| file | Used to remove fine amounts of material from a workpiece. |
| wire brush | Used for cleaning test tubes and narrow mouth laboratory glassware, such as beakers and flasks |
| 24-well plate | A flat plate with multiple "wells" used as small test tubes |
| scoopula | Used primarily in chemistry lab settings to transfer solids: to a weigh paper for weighing, to a cover slip to measure melting point, or a graduated cylinder, or to a watch glass from a flask or beaker through scraping. |
| spatula | Used for scraping, transferring, or applying powders and paste like chemicals or treatments |
| funnel | Used to channel liquid or fine-grained substances into containers with a small opening. |
| test-tube rack | Used to hold upright multiple test tubes at the same time. |
| (crucible) tongs | Large pincers for grasping and lifting vessels of heat-resistant material used in high temperature chemical reactions |
