You will write the name and description of each item and a quick drawing if needed. • Presentation will be on my website as well for review. • Glassware ID quiz next class as well as lab safety quiz.
Beaker • General purpose glassware • Used to mix solutions, transport chemicals • Heat chemicals at relatively low temperatures • Not used for measuring volumes
Erlenmeyer Flask • Also general purpose glassware • Functions same as beaker • The sloped sides make it good at mixing/swirling liquids
Test tube • General purpose, mixing chemicals • Can easily examine contents
Test tube rack • Supports test tubes • Warning: hot test tubes will melt it.
Graduated Cylinder • Accurately measures liquid volumes • 50mL and 10mL
Watch glass • Use to slowly and gently evaporate liquids • Can be used as a lid for beakers
Rubber Stopper • Used as a “lid” for flasks and test tubes
Scoopula • Transfer solids, scoop chemicals
Evaporating dish • Heat or evaporate liquids or solids

Test tube clamp • Duh!
Utility Clamp • Used to support a test tube specifically, or any glassware
Ring Stand • Used to support various clamps
Iron Ring • Supports clay triangle and wire mesh
Electronic Balance • Accurately measures mass to .001 g
Hot Plate • Used to heat substances at low temperatures
Wire Mesh • Used to support glassware on the ringstand • Disperses heat
Bunsen burner • High temperature heat source
Water Bottle (H2O) • Pure water (H2O), used only as directed or for making solutions. • Not used for cleaning or a squirt gun.
Cleaning Brushes • Flask brush • Beaker brush
Cleaning brushes • Test tube brush • Graduated cylinder brush
Well plate • Used to observe small scale chemical reactions
Buret • Used to deliver very precise amounts of • liquids in a titration
