The high school chemistry lab should be equipped with enough equipment to perform all necessary exercises in the curriculum. The equipment should be sufficient in quantity to enable all students to perform laboratory tasks in the time allotted. Clean and well-maintained equipment increases the quality of the exercises and reduces risk of injury in the laboratory. While some laboratories will include additional equipment necessary for the completion of tasks unique to that curriculum, all high-school chemistry laboratories should have certain basic equipment.
Common safety equipment includes an emergency shower, emergency eye wash station, a fire blanket, safety glasses for all students and instructors, and lab coats for all. All safety equipment must be in working order and all lab personnel should be competent in their use.
Chemistry labs need equipment to measure volumes and mass. These include electronic scales and triple-beam balance to determine mass, and for measuring volumes, 10 ml graduated cylinders, 100 ml graduated cylinders, measuring pipettes and pipette bulbs.
Burners and Ring Stands
Ring stands are typically coupled with burners to provide an effective means of heating reagents. They can also be used to hold the equipment for other experiments, such as acid-base titrations. This equipment set includes a Bunsen burner, burner hose, ring stand, ring stand clamp, support ring, utility clamp, wire gauze, and striker. An appropriate number of equipment sets will be necessary to serve each student or small group of students.
One image many people have of a chemistry laboratory is the variety of beakers (50 ml to 400 ml), Erlenmeyer flasks (125 ml and 250 ml), volumetric flasks, Florence flasks, filter flasks, and racks of test tubes. Ensure the right glassware at the right sizes are available.
Some laboratory exercises may require crucibles, crucible tongs, clay triangles, watch glasses, stirring rods, filter funnels, mortar and pestle, chemical spoons, wash bottles, test-tube racks, test-tube holders, and various stoppers for tubes and flasks. Be sure to have beaker and test tube brushes available for cleaning the equipment, as well as appropriate cleansing substances.
