Glassware Identification

• 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 • 50 m. L and 10 m. L

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

Glass Stirring rod • Duh!

Crucible • Heat solids to very high temperatures • Fragile

Clay Triangle • Supports crucible when being heated

Pipet • Transfer small, amounts of liquids

Crucible Tong • Designed to pick-up a crucible

Beaker Tong • Designed to pick up a beaker

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 (H 2 O) • Pure water (H 2 O), 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

Mortar and pestel • Grinding solids

Temperature probe • Accurately measures temperatures in celsius
