PICTURE USE
beaker
Used to hold and heat liquids. Multipurpose and essential in the lab.
brushes
Used to easily clean the inside of a test tubes and other glassware.
Buchner funnel
Used with vacuum flask for performing vacuum filtration.
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.
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
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.
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.
glass stir rod
Used to stir liquids. They are usually made of glass.
graduated cylinder
Used to measure the volumes of liquids.
hot plate
Used for heating substances and liquids in beakers and flasks.
Meker Burner
Used for heating and exposing items to flame.
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.
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.
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.
scoopula
For scooping out small or large amounts of chemicals from bottles, etc.
separatory funnel
For separating layers of immiscible liquids or for dropping liquids.
spatula
Used for moving small amounts of solid from place to place.
striker
Used to light a gas burner.
test tube
Used for storing, mixing, and heating small amounts of chemicals.
test tube holder
Used to hold test tubes while heating.
test tube rack
Used to hold test tubes while reactions happen in them or while they are not needed.
thermometer
Used to take temperature of solids, liquids, and gases.
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
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.
wing top
For obtaining broad, fishtail flame that heats large area and smoothly bends glass.
wire gauze
Used with a ring clamp to support glassware over a Bunsen burner. Spreads flame out for more even heating.NAME
