Laboratory Equipment

Question 1

Used for storing, heating, or mixing small amounts of chemicals.

Answer 1

Test Tube

Question 2

A round bottomed vessel with a long neck. It is used to hold liquids and can be easily swirled and heated. It can also easily be capped by rubber or glass stoppers.

Answer 2

Florence Flask

Question 3

Used for more carefully measuring the volume of a liquid. The smaller the diameter of the tube, the more specific the measurement will be. \

Answer 3

Graduated Cylinder

Question 4

Used to very accurately measure one specific volume of liquid. A line on the neck indicates how far to fill for the indicated volume.

Answer 4

Volumetric Flask

Question 5

A round piece of glass that is slightly concave. It can hold a small amount of liquid or solid. They can be used for evaporation purposes and also can function as a lid for a beaker.

Answer 5

Watch Glass

Question 6

A triangle formed with ceramic cylinders wrapped around a metal frame, with an open center used to suspend crucibles.

Answer 6

Clay Triangle

Question 7

Used to produce a flame in the lab. Connected to a flammable gas source via a tube. A knob at the bottom controls gas flow, and a rotating collar controls air flow.

Answer 7

Bunsen Burner

Question 8

Used to scoop chemicals, often from the chemical’s container onto a weigh boat for massing.

Answer 8

Weigh Boat

Question 9

Walk into class and say this phrase to Mr. Wade to receive a bonus point on the quiz.

Answer 9

Take me to your leader

Question 10

Attached to ring stand and with wire gauze used to hold beakers or flasks over a heat source, or to allow a funnel to drain into another container.

Answer 10

Ring Clamp

Question 11

Used for mixing, heating, and stirring chemicals. Includes a lip for pouring and marks for estimating volume. Due to the lip around the rim, there are no lids, although a watch glass may be used to cover it to prevent splashing or contamination

Answer 11

Beaker

Question 12

A small clay cup made of a material that can withstand extreme temperatures. They are used for heating substances and come with a lid.

Answer 12

Crucible and Cover

Question 13

Used for the extremely accurate measurement of a volume of liquid. A mark above the bulb indicates the level to which the liquid should be drawn into the tube for the indicated volume.

Answer 13

Volumetric Pipette

Question 14

Used to close flasks or test tubes, and come in many different sizes. The sizes are from 0 to 8 (the bigger the number, the larger). May have holes for thermometers and for other probes that may be used.

Answer 14

Rubber Stoppers

Question 15

A ceramic bowl in which a solid is crushed or gound using a ceramic tool.

Answer 15

Mortal and Pestle

Question 16

These are small glass tubes with narrow tips on one end and a rubber bulb on the other. They suck up liquid that can then be squeezed out in small drops.

Answer 16

Dropper Pipette

Question 17

Made of stainless steel and used to handle small pieces of solid material. Commonly referred to as tweezers.

Answer 17

Forceps

Question 18

Used to suspend burettes, beakers, flasks, crucibles, etc. above other containers or, in some cases, a heat source

Answer 18

Ring Stand

Question 19

Used to hold a test tube while heating it.

Answer 19

Test Tube Holder

Question 20

An adjustable device used to connect a buret (or test tube) to a ring stand.

Answer 20

Burette/Test Tube Clamp

Question 21

Used to stir chemicals. The flexible attachment is used to transfer solid residues from the walls of a glass container.

Answer 21

Stirring Rod and Rubber Policeman

Question 22

A ceramic bowl used to evaporate the liquid away from a small volume of solution

Answer 22

Evaporating Dish

Question 23

Used for transferring liquids (sometimes solids) to containers with small openings, in order to prevent spills. They can also be used with filter paper in the process of filtration. May be made of glass or plastic, although glass better resists chemical reactions.

Answer 23

Funnel

Question 24

Used for measuring an exact volume of a liquid and transferring it to another container. Graduation marks are used to indicate volumes.

Answer 24

Graduated Pipette

Question 25

A glass tube that is open at the top and comes to a narrow pointed opening at the bottom. Above the bottom opening is a stopcock that can be turned to control the amount of liquid being released. There are markings along the length of the tube that indicate the volume of liquid present. It is used for extremely accurate addition of liquid. By adjusting the stopcock, the amount of liquid that is released can be slowed to a drop every few seconds. These are one of the most accurate tools in the lab.

Answer 25

Burette

Question 26

Used for handling crucibles, evaporating dishes, and other hot objects.

Answer 26

Crucible Tongs

Question 27

Used to pick up a hot beaker.

Answer 27

Beaker Tongs

Question 28

Filled with distilled water and used to rinse or wash other containers.

Answer 28

Wash Bottle

Question 29

A glass vessel with a narrow neck that expands towards its base. This allows easy mixing and swirling without too much risk of spilling. The narrow opening also allows for the use of a rubber or glass stopper.

Answer 29
