There is a huge amount of apparatus found in a laboratory so I have chosen to select only a few of the items here. Click on the links to see pictures on the corresponding websites.

• Beakers or flasks: These are used to store and hold particular chemical compounds and can be used to help with mixing one component with another. http://mwsu-bio101.ning.com/profiles/blogs/the-whole-of-science-is
• Condenser: These may come in different shapes but the main purpose is to cool down gases or steam and allow them to pass through into another container such as a beaker.

• Funnel: This may be used to help prevent spillages and make transferring a potentially messy substance such as a powder or liquid safely into another container.

• Bunsen burner: This is used to heat up items in the laboratory as it gives off a small flame that can be adjusted in intensity.

• Centrifuge: This is a machine used to separate two or more compounds from each other. It works by spinning the small test tubes around very fast. http://www.scienceclarified.com/Ca-Ch/Centrifuge.html
• Test tubes: These make up the most basic and fundamental equipment found in the laboratory. They can be used to store liquids, can be heated under a Bunsen Burner and can even be used in storing chemical compounds. http://www.narangindustries.com/lact_thermo_testt.htm

Some Tools and Their Uses

1. Beaker = a liquid-measuring container
2. Barrette = measures volume of solution
3. Clay triangle = a wire frame with porcelain used to support a crucible
4. Wire gauze = used to spread heat of a burner flame
5. Test tube = used as holder of small amount of solution
6. Forceps = holds or pick up small objects
7. Graduated cylinder = measures approximate volume
8. Graduated pipette = measures solution volumes
9. Condenser = used in distillation
10. Crucible = used to heat a small amount of a solid substance at a very high temperature                                                                                                                                   
Beaker - a liquid-measuring container
clay triangle - a wire frame with porcelain used to support a crucible
wire gauze - used to spread heat of a burner flame
test tube - used as holder of small amount of solution
forceps - holds or pick up small objects
graduated cylinder - measures approximate volume of liquids
graduated pipette - measures solution volumes
condenser - used in distillation
crucible - used to heat a small amount of a solid substance at a very high temperature
funnel - used to transfer solids and liquids without spilling
thermometer - measures temperature
balance - measures mass of material
pH meter - measures acidity of solutions
centrifuge - separates materials of varying density
pipette - used to transfer measured substances into another vessel
droppers - for addition of liquids, drop by drop
glass funnels - for funneling liquids from one container to another, or for filtering when equipped with filter paper.
Graduated cylinders - for measurement of an amount of liquid. The
volume of liquid can be estimated to the nearest 0.1 mL with practice.
Ring stand (with rings or clamps) - for holding pieces of glassware in place.
Test tubes - for holding small samples or for containing small-scale reactions
test-tube holders - for holding test tubes when tubes should not be touched
tongs - similar function to forceps, but are useful for larger items
volumetric flasks - to measure precise volumes of liquid or to make precise dilutions.
Wash bottles - for dispensing small quantities of distilled water.
Watch glasses - for holding small samples or for covering beakers or evaporating dishes.
Wire gauze on a ring - supports beakers to be heated by Bunsen burners
