Common Laboratory tools

Their uses.

These are containers that are used to hold and heat liquids.

It performs a multipurpose and essential purpose in the lab.

Beaker

This is for holding hot solid objects.

They are used for holding many different things such as flasks, crucibles, and dishes when they are hot.

Crucible tong

Test tube brushes are used for easily cleaning the inner parts of a test tube

Test Tube brush

Glass Plates

This is used to contain substances for testing .

This glass is also to hold solids for weighing but not for heating.

A wire gauze is used to support beakers or flasks when heating.

Wire Gauze

Graduated cylinder

Used to measure volume of liquids

A mortar and pestle are used for breaking/crushing solid substances into smaller particles/ powder. This enables the solid dissolve better.

Mortar and pestle

Dropper is used in transferring small amount of liquid and for dropping liquid into another substance.

Dropper

This is used to hold large amount of liquid and to heat and store liquids. The advantage the Erlenmeyer Flask has is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.

Erlenmeyer flask

A funnel is used to support filter paper during filtration and for pouring liquids into containers with small mouth or opening

Funnel

The stir rods are used for stirring or mixing solutions. They are usually made of glass. Stir Rods are very useful in the lab setting.

Iron stand and clamp holder is used as a support when assembling a set up.

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

Test Tube

Stopper is used to seal a container like Erlenmeyer flask and Florence flask. Stoppers come in many different sizes. The sizes are from 0 to 8. Stoppers can have holes for thermometers and f

or other probes that may be used.

Stopper

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 rack

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

Test tube holder

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

Laboratory thermometer

This is used to support equipment or apparatus for heating purposes which need not attached

Tripod

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.

Watch glass

Volumetric flask isusedTo 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.

Volumetric flask

Spatula Used to transfer small amount of solid/powdered chemicals

Spatula

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

wash bottle

Pipette is used to transfer liquid solution by suction.

Pipette

Florence flask Used to contain solution The Florence Flask is 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.

Florence flask

These 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.
