Lab Equipment Idenification

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

Volumetric flask

  • A flask that is calibrated to contain a precise volume at a particular temperature.

  • Volumetric flasks are used for precise dilutions and preparation of standard solutions.

Test tube

  • General purpose, mixing chemicals

  • Can easily examine contents

  • Transport chemicals

Test tube rack

  • Supports test tubes

  • Warning: hot test tubes will melt it.

Graduated Cylinders

  • Accurately measures liquid volumes ONLY

  • 50mL and 10mL

  • Sight along the bottom of the meniscus to read volumes.

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

  • A small ceramic dish in which liquids are heated over a flame so that they evaporate, leaving a solid residue.

Glass stirring rods

  • Stir or mix solutions or solid chemicals.

Crucible with lid

  • A ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures.

Clay triangle

  • Supports crucible when being heated

Pipette

  • Used to transport a precise, measured volume of liquid

Crucible tong

  • Used to pick up a hot crucible

Beaker tong

  • Used to pick up a beaker

Test tube tong

  • Used to pick up a test tube

Utility Clamp

  • Used to support a test tube, burette or any glassware

  • Use along with a ring stand

Ring Stand

  • Used to support various clamps

Iron ring

  • Supports clay triangle on ring stand

Electronic Balance

  • Accurately measures mass to .001 g

  • Very expensive, be careful

Pneumatic Trough

  • Used for collecting gases, such as hydrogen, oxygen, and nitrogen.

Hot plate

  • Used to heat substances at low temperatures

Wire Mesh

  • Used to support glassware on the ring stand 

  • Disperses heat

Bunsen Burner

  • High temperature heat source

Burette

  • Used to deliver very precise amounts of liquids in a titration

Temperature Probe

  • Accurately measures temperatures in celsius
