Laboratory Apparatus And Their Uses

Lab apparatus is an important part of chemistry and science in general. In this page you will learn about lab equipment and its uses.

BeakerUsed to hold and heat liquids. Multipurpose and essential in the lab.
BottleBottles can be ued for storage, for mixing and for displaying.
Bunsen BurnerBunsen 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.
BuretThe buret is used in titrations to measure precisely how much liquid is used.
CrucibleCrucibles are used to heat small quantities to very high temperatures.
Erlenmeyer FlaskThe 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.
Evaporating DishThe Evaporating Dish is used to heat and evaporate liquids.
Florence FlaskThe 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.
Food ColoringFood Coloring is used in many experiments to show color change and to make the experiment more exciting.
FunnelThe Funnel is a piece of eqipment that is used in the lab but is not confined to the lab. The funnel can be used to target liguids into any container so they will not be lost or spilled.
MicrospatulaThe Microspatula, commonly called a spatula, is used for moving small amounts of solid from place to place.
Mortar and PestleThe Mortar and Pestle are used to crush solids into powders for experiments, usually to better dissolve the solids.
Paper TowelsPaper Towels are essential to the lab environment. They will be used in almost every lab.
PipetThe pipet is used for moving small amounts of liquid from place to place. They are usually made of plastic and are disposable
Ring StandRing 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.
Stir RodThe stir rods are used to stir things. They are usually made of glass. Stir Rods are very useful in the lab setting.
StopperStoppers 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 BrushThe test tube brush is used to easily clean the inside of a test tube.
Test tube HolderThe holder is used to hold test tubes when they are hot and untouchable.
Test tube RackThe testtube rack is used to hold testtubes while reactions happen in them or while they are not needed.
ThermometerThe thermometer is used to take temperature of solids, liquids, and gases. They are usually in oC, but can also be in oF
TongsTongs are used to hold many different things such as flasks, crucibles, and evaporating dishes when they are hot.
TriangleThe triangle is used to hold crucibles when they are being heated. They usually sit on a ring stand
Volumetric FlaskThe 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.
Watch GlassThe watch glass is used to hold solids when being weighed or transported. They should never be heated.


  1. Lab equipments are important for research lab. lab equipments play key role in experiments and information you shared about lab equipments is good.
    brix refractometer

  2. we are Manufacturer/Exporter/Importer/Dealer/Wholesaler & supplier of lab burners in India for schools, colleges and Teaching labs to all middle east countries. read more

  3. Interesting to shear chemistry knowledge thanks.

  4. as beaker covers or as evaporating dishes. Clay triangles are wire-frames with porcelain on it, Auction Services for R&D Equipment

  5. This was a really great contest and hopefully I can attend the next one. It was alot of fun and I really enjoyed myself.. Textile Testing Equipment

  6. The testing of textile products is an expensive business. A laboratory has to be set up and furnished with a range of test equipment.where testing may be carried

    out to improve the product or to prevent sub-standard merchandise progressing further in the cycle - See more at:
