Common Laboratory Apparatuses and their Uses


Beaker Container of liquids and solutions for heating purposes Used to hold and heat liquids. Multipurpose and essential in the lab.

Crucible tong:

Crucible tong For holding hot solid object Tongs are used to hold many different things such as flasks, crucibles, and evaporating dishes when they are hot.

Test tube brush:

Test tube brush For cleaning the inner part of the test tube and other container The test tube brush is used to easily clean the inside of a test tube.

Triple beam balance:

For weighing objects and solid chemicals Triple beam balance

Separatory funnel:

Separatory funnel To separate immiscible liquid

Clamp universal:

Clamp universal A combination of clamp holder and extension clamp used to hold test tubes and other apparatuses

Reagent bottle:

Reagent bottle To contain/store chemicals Bottles can be used for storage, for mixing and for displaying.

Clay triangle:

Clay triangle To support the porcelain crucible when heating The triangle is used to hold crucibles when they are being heated. They usually sit on a ring stand


condenser Used in simple distillation set up

Distilling flask:

Distilling flask Used to contain liquids/solutions to be distilled


dropper Used in transferring small amount of liquid and for dropping liquid into another substance

Evaporating dish:

Evaporating dish Porcelain container used to direct evaporation over a wire gauze The Evaporating Dish is used to heat and evaporate liquids

Erlenmeyer flask:

Erlenmeyer flask Conical flask used to hold large amount of liquids The Erlenmeyer Flask is used to heat 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.


funnel Used to support filter paper during filtration and for pouring liquids into container with small mouth or opening

Glass rod:

Glass rod For stirring or mixing solutions and as passage or medium when pouring liquids from one container to another to avoid spillage The stir rods are used to stir things. They are usually made of glass. Stir Rods are very useful in the lab setting.

Set of weights:

Set of weights Used as an accessory in weighing chemicals

Graduated cylinder:

Graduated cylinder Used to measure volume of liquids

Iron stand and clamp holder:

Iron stand and clamp holder Used as a support when assembling a set up

Iron ring:

Iron ring Support the wire gauze or the clay triangle when heating and support the funnel when filtering substances Ring stands are 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.

Mortar and pestle:

Mortar and pestle For pulverizing solid substances into smaller particles The Mortar and Pestle are used to crush solids into powders for experiments, usually to better dissolve the solids.

Porcelain crucible:

Porcelain crucible For heating substances in the absence of air at high temperature Crucibles are used to heat small quantities to very high temperatures.

Rubber tubing:

Rubber tubing Used as a delivery tube for gases and liquids

Alcohol lamp:

Alcohol lamp For heating purposes

Test tube:

Test tube Container for small amount of liquid and solid substances for testing or heating


stopper To seal a container like Erlenmeyer flask and F lorence flask 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.

Test tube rack:

Test tube rack For drying test tubes and holding while observing chemical reactions The test tube rack is used to hold test tubes while reactions happen in them or while they are not needed.

Test tube holder:

Test tube holder For holding test tubes when heating contents The holder is used to hold test tubes when they are hot and untouchable.

Laboratory thermometer:

Laboratory thermometer To measure temperature of substances The thermometer is used to take temperature of solids, liquids, and gases. They are usually in o C , but can also be in o F

Thistle tube:

Thistle tube To introduce liquids directly to the bottom of the flask

Rubber bulb aspirator:

Rubber bulb aspirator In sucking or absorbing liquids of the flask


tripod To support equipment or apparatus for heating purposes which need not attached

Watch glass:

Watch glass To contain substances for analysis or testing The watch glass is used to hold solids when being weighed or transported. They should never be heated.

Wire gauze:

Wire gauze To support beakers or flasks when heating

Burette or buret:

Burette or buret Used in acid-base titration; to contain and deliver specific amount of solution The buret is used in titrations to measure precisely how much liquid is used.

Volumetric flask:

Volumetric flask To prepare and to contain standard solutions The Volumetric flask is used to measure one specific volume. They are mostly used in mixing solutions where a one liter or one half a liter is needed.


Spatula Used to transfer small amount of solid/powdered chemicals

Wash bottle:

Wash bottle Used to wash out solid particles during filtration and for washing narrow-mouthed containers


pipette Used to transfer liquid solution by suction

Florence flask:

Florence flask Used to contain solution The Florence Flask is used for heating subtances 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.

Cork borer:

Cork borer Used to make hole in cork fitting

Bunsen burners:

are used for heating and exposing items to flame. They have many more uses than a hot plate, but do not replace a hot plate. Bunsen burners
