LABORATORY TOOLS

1. Beakers – used to hold and heat liquids. They are essential in the laboratory, and they are used for several purposes.

2. Reagent Bottle – bottles can be used for storage, for mixing, and for display.

3. Bunsen Burner – Bunsen burners are used for heating and exposing items to flame.

4. Buret – is used in chemical analysis to measure precisely how much is used for filtration.

5. Crucible – is used to heat small quantities of chemicals/substances in very high temperatures. They can withstand temperatures high enough to melt or alter their contents.

6. Erlenmeyer Flask – is used 
to heat and store liquids. The advantage of the Erlenmeyer flask is that the bottom is wider than the top so it will heat up quicker because of the greater surface area exposed to the heat.

7. Evaporating Dish – is used to heat and evaporate liquids.

8. 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.

9. Funnel – is a piece of equipment that is used in the laboratory but is not confined to the laboratory. The funnel can be used to transfer liquids into another container so they will not spill.

10. Microspatula – commonly called a spatula, is used for transferring small amounts of solid from one container to another.

11. Mortar and Pestle – are used to crush solids into powders for experiments, usually to dissolve the solids better.

12. Pipet – is used for moving small amounts of liquid from one container to another. It is usually made of plastic and is disposable.

13. Ring Stand – ring stands are used to support items being heated. Clamps or rings can be used so that other items may be placed above them for heating using a Bunsen burner.

14. Stirring Rod/Glass Rod – the stirring rods are used to stir solutions to dissolve substances. They are usually made of glass. Stirring rods are very useful in the laboratory setting.

15. Stopper/Cork – stoppers are used to seal test tubes and flasks. They come in different sizes ranging from 0 to 8.

16. Test Tube Brush – is used to easily clean the inside of a test tube.

17. Test Tube Holder – is used to hold test tubes while being heated.

18. Test Tube Rack – is used to hold test tubes upright while observing reactions or when test tubes are not used in experiments.

19. Thermometer – is used to take temperature of solids, liquids, and gases.

20. Tongs – are used to hold many different things such as flasks, crucibles, and evaporating dishes when they are hot.

21. Clay Triangle – is used to hold crucibles when they are being heated. They usually sit on a ring stand.
