Laboratory Equipment

Question 0

Bunsen Burner

Answer 0

Bunsen burners are used for heating and exposing items to flame. They have many more uses than a hot plate, but do not replace a hot plate.

Question 1

Beaker

Answer 1

Used to hold and heat liquids.

Multipurpose and essential in the lab.

Question 2

Buret

Answer 2

The buret is used in titrations to measure precisely how much liquid is used. The buret used in ChemLab comes with a titration dialog box.

Question 3

Erlenmeyer Flask

Answer 3

The Erlenmeyer Flask is used to heat and store liquids. The advantage to the Erlenmeyer Flask is that the bottom is wider than the top so it will beat quicker because of the greater surface area exposed to the heat.

Question 4

Evaporating Dish

Answer 4

The Evaporating Dish is used to heat and evaporate liquids.

Question 5

Florence Flask

Answer 5

The Florence Flask is used for heating substances that need to be heated evenly. The burned bottom allows the heat to distribute through the liquid more evenly. The Florence Flask is mostly used in distillation experiments.

Question 6

Funnel

Answer 6

The Funnel is a piece of equipment that is used in the lab but is not confined to the lab. The funnel can be used to target liquids into any container so they will not be lost or spilled. A special funnel is a Büchner funnel, which is used to filter with vacuum suction.

Question 7

Graduated Cylinder

Answer 7

Used for measuring varying, usually medium sized, amounts of liquid. It is not as precise (accurate) as a volumetric pipette.

Question 8

Spatula

Answer 8

A spatula is used for moving small amounts of solid from place to place.

Question 9

Mortar and Pestle

Answer 9

The Mortar and Pestle are used to crush solids into powders for experiments, usually to better dissolve the solids.

Question 10

Pipet (disposable and volumetric)

Answer 10

This type of pipet is used for moving small amounts of liquid from place to place. They are usually made of plastic or glass and are disposable (in ChemLab they are called Eye Dropper). There are also graduated or volumetric pipets, which are used for precisely measuring small volumes of liquids.

Question 11

Ring Stand

Answer 11

Ring stands are used to hold items being heated. Clamps or rings can be used so that items may be placed above the lab table for heating by Bunsen burners or other items.

Question 12

Stir Rod

Answer 12

The stir rods are used to stir things. They are usually made of glass. Stir rods are very useful in the lab setting.

Question 13

Stopper

Answer 13

Stoppers come in many different sizes. The sizes are from 0 to 8. Stoppers can have holes for thermometers and for other proves that may be used.

Question 14

Test tube holder

Answer 14

The holder is used to hold test tubes when they are hot and untouchable.

Question 15

Thermometer

Answer 15

The thermometer is used to take temperature of solids, liquids, and gases. They are usually in Celsius units, but can also be in Fahrenheit units.

Question 16

Triangle

Answer 16

The triangle is used to hold crucibles when they are being heated. They usually sit on a ring stand.

Question 17

Volumetric Flask

Answer 17

The volumetric flask is used to measure ‘one’ specific volume. They are mostly used in mixing solutions. In comparison, graduated cylinders are used for various, differing volumes.

Question 18

Watch Glass

Answer 18

The watch glass is used to hold solids when being weighed or transported. They should never be heated.
