Lab Equipment *These are the pieces of equipment you may see in class. You will be expected to know the names of the items and the actual use for each*
Beaker Holds and measures approximately large volumes of liquid. Also used as a water bath for heating test tubes.
Conical Flask / Rubber Stopper A narrow-mouthed container used to transport, heat or store substances, often used when a stopper is required. Also known as an Erlenmeyer Flask. Stopper closes off flask like in a bath tub.
Burette A vertical cylindrical piece of laboratory glassware with a volumetric graduation on its full length and a precision tap, or stopcock with plug and bore, on the bottom. It is used to dispense known amounts of a liquid reagent in experiments for which such precision is necessary, such as a titration experiment.
Bunsen Burner Produces a flame to heat using gas and air.
Graduated Cylinder Graduated tube with a spout that is used especially for measuring small amounts of liquid with precision.
Hot Plate Produces heat like a stove's burner. Used in most experiments when open flames can be an issue.
Glass Stirring Rod Used to stir or mix solutions that are either hot or cold.
Tongs Used to pick up glassware that may be hot including beakers, crucibles and flasks.
Lab Stand / Ring Stand Test Tube Holder/ Wire Gauze Stand that allows clamps to be attached for various experiments. Ring clamps attach to a lab stand and are used to hold a variety of lab equipment many times with the wire gauze across it. Test tube holders allow you to clamp test tubes to the stand for heating. Other clamps will hold things like conical flasks and burettes for experiments.
Triple Beam Balance / Scale Used to measure the mass of an object usually in grams or kilograms depending on the chemical.
Funnel Used to pour liquids or solids into another piece of lab equipment. May be made out of glass or plastic and usually have long spouts.
Test Tube / Holder / Rack / Brush A small glass container used to view chemical reactions or to heat small amounts of a substance. The rack and holder are each to hold the test tube if they may be hot or you need to set them down. The brush is only for test tubes and small graduated cylinders to clean them.
Crucible / Evaporating Dish Crucible - A ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. Evaporating Dish - A small shallow dish used in laboratories to heat and evaporate substances.
Eye Dropper Used to add small amounts of a liquid to an experiment or to remove liquid that has a solid settled underneath it.
Striker / Lighter Used to create a spark to start a Bunsen burner. If constantly sparked they will no longer work as the flint wears down.
Watch Glass A shallow glass dish used as an evaporating surface or to cover a beaker. Easily breakable!
Spatula Used to remove a portion of a solid from a chemical bottle or a test tube. Should only be used in one chemical and then thoroughly washed.
Wash Bottle The wash bottle contains deionized water and is used to rinse glassware, among other things.
Litmus Paper Indicates whether a solution is acidic or basic. Usually found as red or blue.
