Laboratory Equipment

1
Laboratory Equipment
2
Graduated Cylinder

• Measure the volume of liquids in mL.
• More accurate than flask/beaker
• Use the graduate best sized for the volume being
  measured

3
Reading a Graduated Cylinder

• Meniscus curve caused by the surface tension
  between the liquid and the container
• Read across the meniscus
• Have the meniscus at eye level

4
Beaker

• Approximate measure of volume
• Not very accurate
• Usually used as a container for mixing or holding
  chemicals.

5
Metal Ring Ring Stand

• Used as a support to hold beakers, crucibles, etc
• Often to heat

6
Wire Gauze

• Used to support a container (such as a beaker or
  flask) during heating

7
Bunsen Burner

• Used to heat chemicals, bend glass tubing

8
A Bunsen Burner with a Ring Stand
9
Test Tubes in Test Tube Rack

• TEST TUBE is used to hold chemicals during
  heating or other reactions
• TEST TUBE RACK supports the test tubes.

10
Erlenmeyer Flask

• Approximate measurements of volume.
• Usually used as a mixing vessel or a container
  for heating

11
Lab spatulas scoopulas

• Used to transfer solid chemicals
• A spatula is smaller and may also be used

12
Stirring Rod

• Used to mix chemicals
• Used to add acid to water

13
Pipet

• A calibrated plastic (or glass) tube used to
  transport small amounts of liquid via suction

14
Safety Goggles

• Protective eyewear
• Used to protect eyes from chemicals, glass, and
  other objects

15
Thermometer

• Used to measure temperature
• Measures in degrees Celsius

16
Weigh boat

• Plastic container used to weigh and transfer
  solids to another container

17
Tongs

• Metal/Crucible
• Can be used to hold or pick up many items
• Also called crucible tongs

• Rubber Coated
• Used to hold or move a hot beaker

18
Funnel

• A pipe with a wide top and narrow bottom that
  is used to guide liquid or small solid particles
  into a small opening

19
Watch Glass

• Shallow glass dish
• Used to cover beakers
• Can be used to recover solid from solution

20
Evaporating Dish

• Used to heat and evaporate liquids
• Can be used to heat solids to their melting points

21
Electronic Balance

• Measures the mass of an object
• Tare or zero will reset the scale reading
