									Equipment List
You will be given 1-4 pieces of equipment along with their equipment cards. You are to copy the description of use for the equipment onto this chart. After each person in the group has written down the information, we will present our equipment to the class. When another group presents their equipment, next to the name of the item, draw a sketch of the item and write down a description. Some items will not be drawn instead, their location will be listed.

Name of equipment 1. Erlenmeyer flask

Sketch of equipment or location in room

Description of use:

2. graduated cylinder

3. pipette

4. test tube

Erlenmeyer flasks are used to mix chemicals. We do not rely on the graduated markings on the side of the flask. You swirl the flask gently to mix the contents. Graduated cylinders are used to measure precise volumes of liquids. You read graduated cylinders to one place beyond where the scale is written. A pipette measures precise volumes of liquid, usually less than 25 mL. You estimate the last digit by reading one place beyond what is written on the pipette. A test tube is an elongated piece of glass in which someone performs a reaction. They are also used to hold liquids until later use. A test tube rack holds test tubes.

6. beaker

A beaker holds liquids. We can mix liquids in a beaker by placing a magnetic stir bar inside the beaker and by putting the beaker on a magnetic stirrer. We can also stir with a glass rod. We do not rely on the graduations on the side of the beaker for accuracy.


A funnel makes it easier to put solids or liquids into another container, especially if the container has a narrow neck. We evaporate liquids from solids in an evaporating dish.

8. evaporating dish

9. ring clamp

A ring clamp attaches to a ring stand. It can support equipment.

10. ring stand

A ring stand is used to support ring clamps, utility clamps, or buret clamps. A wire gauze can be put on top of a ring stand so that a beaker can be supported. A Bunsen burner would be located below the wire gauze. The wire gauze helps spread out the heat. A Bunsen burner is used to heat objects.

11. wire gauze

12. Bunsen burner

13. scoupula, chemical spoon 14. eye dropper/ medicine dropper 15. utility clamp

A scoupula, chemical spoon, or spatula is used to weigh chemicals. We use a separate weighing utensil for each chemical. An eye dropper/ medicine dropper lets us administer liquids drop by drop. A utility clamp can hold many cylindrical objects like thermometers, burets, or test tubes.

16. crucible

A crucible is used to heat up hydrates or solids. Crucibles can crack if they get wet and are heated. Crucible tongs hold crucibles so we don’t burn ourselves.

17. crucible tongs

18. test tube holder

A test tube holder holds a test tube that we may have in a flame or warming in a hot water bath. A striker lights a Bunsen burner. At this time we don’ t have any that work. Mortar and pestles are used to grind up materials. One should never bang a pestle in the mortar because it can crack the mortar. A scale/balance is used to weigh things.

19. striker

20. mortar and pestle

21. scale/ balance

22. pipette filler

23. volumetric flask

A pipette filler lets us draw liquid into a pipette. You rotate the little wheel which creates an area of low pressure so that the liquid will want to enter the pipette. A volumetric flask is used to measure precise liquids when you make a Molar solution. A buret is used to add precise amounts of liquid in a controllable manner.

24. buret

25. eye wash


26. fire blanket


An eye wash is used to wash out your eyes if something gets in them. We should never need to use the eye wash because you will always be wearing your goggles. A fire blanket is wrapped around a person who is on fire so that the fire can be put out. Stop, drop, roll. An emergency shower is used to wash off a person who is seriously contaminated with a chemical. I hope we never have to use it. Goggles are used to cover your eyes so that you do not get any chemicals in them. The inconvenience of goggles is temporary, the inconvenience of blindness is permanent. The fire extinguisher is to be used on surfaces that are on fire.

27. emergency shower


28. goggles


29. fire extinguisher


30. fume hood


A fume hood sucks out bad odors. We do not have one in S-5.

31. first aid kit


The first aid kit is used to clean cuts and to protect them from future contamination. At this time it consists of band aids. Forceps and tweezers are used to hold small objects that our fingers should not touch.

32.forceps or tweezers

33. thermometer

34. watch glass

A thermometer is used to measure the temperature of solids, liquids, or gases. You read a thermometer and guess the next digit based on the scale. Our thermometers will be using Celsius degrees A watch glass is used to cover an evaporating dish so that the liquid does not spatter all over the counter. Small volumes of liquid can be evaporated in a watch glass.
