5. Lab Apparatus and their use
Used to hold and heat liquids. Multipurpose and essential in the lab.
brushes
beaker
New Section 5 Page 5

6. Used to easily clean the inside of a test tubes and other glassware.
Bunsen burner
Used for heating and exposing items to flame.
burette
Used in titrations to measure precisely how much liquid has been delivered.
burette clamp
Used to hold burettes on a ring stand.
New Section 5 Page 6

7. clay triangle
Used to hold crucibles when they are being heated. They usually sit on a ring stand.
crucible with lid
Used to heat small quantities to very high temperatures.
crucible tong
Used to hold crucibles and evaporating dishes when they are hot.
disposable pipette
New Section 5 Page 7

8. disposable pipette
Used for moving small amounts of liquid from place to place. They are usually made of plastic
and are disposable
electronic balance
Used for weighing substances or objects, usually in grams.
Erlenmeyer flasks
Used to heat, mix, and store liquids. The advantage to the Erlenmeyer Flask is that the bottom is
wider than the top so it will heat quicker because of the greater surface area exposed to the heat.
evaporating dish
Used to recover dissolved solids by evaporation.
New Section 5 Page 8

9. Florence flask
Used for heating substances that need to be heated evenly. The bulbed bottom allows the heat to
distribute through the liquid more evenly. The Florence Flask is mostly used in distillation
experiments.
forceps
Used for picking up and moving small objects.
glass funnel
Used to pour liquids into any container so they will not be lost or spilled. They are also used
with folded filter paper for filtration.
New Section 5 Page 9

10. graduated cylinder
Used to measure the volumes of liquids.
micropipette
Used for accurately measuring and delivering very small volumes of liquid-usually 1 mL or less.
mortar and pestle
Used to crush solids into powders for experiments, usually to better dissolve the solids.
New Section 5 Page 10

11. pipette with pump
Used for accurately measuring and delivering small volumes of liquid-usually 0.1-10 mL.
ring clamp
Attached to ring stand and with wire gauze used to hold beakers or flasks while they are heated
by a gas burner.
ring stand
Used to hold items being heated. Clamps or rings can be used so that items may be placed above
the lab table for heating by Bunsen burners or other items.
New Section 5 Page 11

12. rubber stopper
Stoppers come in many different sizes. The sizes are from 0 to 8. Stoppers can have holes for
thermometers and for other probes that may be used.
separatory funnel
For separating layers of immiscible liquids or for dropping liquids.
test tube holder
Used to hold test tubes while heating.
New Section 5 Page 12

13. utility clamp
Used to attach test tubes and other glassware to ring stand.
vacuum filter flask
Used with vacuum line and Buchner funnel for vacuum filtration.
volumetric flask
Used to measure one specific volume in mixing accurate solutions.
wash bottle
Used to wash or rinse other containers
New Section 5 Page 13

14. watch glass
Used to hold solids when being weighed or transported. They should never be heated. Can also
be used to cover beakers or other containers.
weigh boat
Used for weighing solids on a balance.
wire gauze
Used with a ring clamp to support glassware over a Bunsen burner. Spreads flame out for more
even heating.
