1 Chemistry Lab Equipment

2

3 Safety Goggles Protect eyes whenever working with chemicals in the lab

4

5 Test Tubes Store/Mix small amounts of substances Heat/Boil substances over a burner

6

7 Beaker Store/Mix substances Heat substances over a burner

8

9 Test Tube Clamp Holds a test tube to a ring stand, usually for purposes of heating

10

11 Test Tube Holder Allows you to hold a test tube over a burner or other heat source without burning your hand

12

13 Test Tube Rack Stores several test tubes

14

15 Test Tube Brush Used to clean test tubes, can be used to clean other equipment as well

16

17 Ring Stand Clamps of any type are placed on this when setting up an experiment

18

19 Plastic Wash Bottles Add small amounts of water to a container Rinse out glassware NOT A SQUIRT BOTTLE!

20

21 Ring Clamp Clamped to a ring stand to support other equipment

22

23 Wire Gauze Usually rests on top of a ring clamp to support a beaker being heated

24

25 Clay Triangle Sits on a ring stand to support a crucible or a funnel

26

27 Crucible and Cover Ceramic equipment used to heat a small amount of solid to very high temperatures

28

29 Evaporating Dish Ceramic equipment used to drive off a small amount of liquid to leave a dry residue

30

31 Funnel Tool to aid pouring Supports filter paper when performing filtration

32

33 Watch Glass Allows things to be set out to dry Can be used as a cover for a beaker

34

35 Dropper Pipet NOT AN EYE DROPPER! Transfers small volumes of liquids

36

37 Stirring Rod with Rubber Policeman Stirring Rod is used to stir mixtures Rubber Policeman is used like a spatula, to scrape out residue I have no idea where a rubber policeman gets its name!

38

39 Erlenmeyer Flask All flasks have a wide base and a narrow neck Erlenmeyer flasks are conical in shape Used to swirl mixtures easily while avoiding spilling

40

41 Florence Flask Again, wide at the base, narrow at the neck Florence flasks are spherical in shape

42

43 Graduated Cylinder Tall, narrow tube used to measure volumes of a liquid NOTE: While beakers and flasks have graduations on them as well, they are NOT AS ACCURATE as graduated cylinders - only use cylinders to measure volume!!!

44

45 Beaker Tongs Can “grab” beakers, especially when hot, easily to move it from one place to another (this is not on your equipment list)

46

47 Crucible Tongs A tool for smaller, finer work, a crucible tongs is used to move hot crucibles (or other objects) Note - tongs are NOT spelled with an “h”!

48

49 Bunsen Burner and Rubber Tubing Bunsen Burner is a common source of heat (flame) in the lab Rubber Tubing is a common means of carrying a gas from one place to another (for Bunsen burners, we will carry natural gas or methane)

50

51 Mortar and Pestle Used to crush or grind solids

52

53 Rubber Stoppers Seals containers (flasks, test tubes)

54

55 Triple Beam Balance Used to obtain the mass of objects (not weigh them!)

56

57 Pneumatic Trough Used to hold a water bath for various reasons

58

59 Forceps Used to pick up small objects NOT TWEEZERS!

60

61 Scoopula Used to transfer solid objects My favorite word in the English language!

62

63 Condensor Used to change a gas to a liquid

64

65 Ceramic Square Generally used like a “trivet” to place a very hot object onto

66
