Study Notes

Basic Laboratory Equipment

Beakers are used to hold solids or liquids that won't release gases when reacted or are unlikely to splatter if stirred or heated.
Erlenmeyer Flasks are used to for solids or liquids that may release gases during a reaction or are likely to splatter if stirred or heated.
Florence Flasks are used for mixing chemicals. They have a narrow neck to prevent splashes.
Graduated Cylinders are used to measure volumes of liquids.
Gas Collecting Bottles are used for collecting large volumes of gases, often by water displacement.
Test Tubes (13 x 100 mm) and Test Tubes (10 x 75 mm) are common sizes for holding and reacting small quantities of liquids or solids.
Test Tube Holders are used to safely hold test tubes that are too hot to handle.
Test Tube Brushes are used to clean test tubes and graduated cylinders, but be careful not to force a large brush into a small test tube as it can break the tube.
Test Tube Racks organize and hold test tubes. Plastic racks can melt in contact with very hot test tubes.
Rubber Stoppers are used to close containers to avoid spillage or contamination. Never heat a container with a stopper in place.
Glass Stir Rods are used to manually stir solutions and to transfer single drops of a solution.
Medicine Droppers are used to transfer small volumes of liquid (less than one mL) and use a “rubber bulb" on top.
Litmus Paper is used to identify acids and bases. Red litmus paper turns blue in the presence of a base, while blue litmus paper turns red in the presence of an acid.
Forceps are used to pick up small objects.
Funnels are used to aid in the transfer of liquids from one vessel to another.
Mohr Pipets are used to measure and deliver exact volumes of liquids.
Wash Bottles are used to deliver a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle.
Weighing Boats are used to weigh solids that will be transferred to another vessel.
Spatulas are used to dispense solid chemicals from their containers. Never transfer chemicals with your bare hands.
Beaker Tongs are used to move beakers containing hot liquids.

Heating and Support Equipment

Bunsen Burners are used for heating nonvolatile liquids and solids.
Evaporating Dishes are used for heating stable solid compounds and elements.
Crucibles are used for heating certain solids, particularly metals, to very high temperatures.
Clay Triangles are used as a support for porcelain crucibles when being heated over a Bunsen burner.
Crucible Tongs are used for handling hot crucibles and other hot objects. NEVER use them to pick up beakers!
Glass Plates are used for semi-micro scale experiments, such as drop reactions and testing acids and bases.
Triangular Files are used to cut glass, a skill that would be taught by an instructor when needed.

Supporting and Clamping Equipment

Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.
Iron Rings connect to a ringstand to provide a stable, elevated platform for the reaction.
Utility Clamps are used to secure test tubes, distillation columns, and burets to the ringstand.
Double Buret Clamps are used to secure burets, which are long graduated tubes used in titration.
Wire Gauze sits on the iron ring to provide a place to safely stand a beaker.
