CHEMISTRY FINAL TEST - Apparatus & Hazard Signs

Beaker

Beaker

• a simple container for stirring, mixing and heating liquids

Conical/Erlenmeyer Flask

• Allows contents to be swirled or stirred during and experiment - narrow neck keeps the contents from spilling out

• Reduces evaporated losses compared to a Beaker

Measuring Cylinder

• Used to accurately measure volume of an object

Where should you read the meniscus? Bottom or Top

Bottom

Volumetric Flask

• Used for making solutions of known volume.

Test Tube

• To contain and heat

Test Tube Rack

• Used to hold and support test tubes containing chemicals and waiting for further operations.

Test Tube Holder

• A gripping device used to carry a test tube after it has been subjected to heat and/or cold temperatures

Dropper

• A tool to transfer small amounts of liquids
(get rickrolled again)

Glass Stirring Rod

• A piece of lab equipment used to mix chemicals and liquids for laboratory purposes

Alcohol Lamp

• Used for heating, sterilization & combustion

Thermometer

• Device used to measure the temperature of a substance

Retort Stand

• A piece of scientific equipment, to which clamps can be attached to hold test tubes and other equipment (such as Burettes)

Evaporating Dish

• Used to evaporate excess water

Funnel

• Used to channel; or fine-grained substances into containers with a small opening

Pestle & Mortar

• A tool used to crush, grind & mix solid substances

Burette

• used to dispense known amount of a liquid in experiments for which precision is necessary (e.g titration experiment)

Flammable
