Laboratory Equipment

Flashcards reviewing common laboratory equipment and their uses.

Pipette Used to transfer fixed quantities of liquid accurately; bulbs, teats, and suction pumps are attached when poisonous liquids are used.

Burette Used to measure, transfer, and dispense variable quantities of liquid accurately.

Graduated measuring cylinder. Used to measure variable quantities of liquid, though less accurate than a pipette or burette.

Erlenmeyer flasks. Used to hold liquids, and chemical reactions are often carried out in them.

Beaker. Used to hold and dispense liquids, as well as to hold solid substances.

Test Tubes. Used to hold small quantities of substances for chemical reactions and when heating substances.

Test tube tong. Used to hold test tubes above an open flame during chemical reactions, preventing burns.

Funnel. Used to transfer liquids from large necked containers into narrow necked containers; some are adapted for separating liquids.

Bunsen burner. Used to provide direct heat of different intensities for chemical reactions and physical changes.

Retort stands, clamps and tripods. Retort stands hold apparatus in place, clamps attach parts to the retort stand, and tripods support glassware above a flame.

Thermometer. Used to measure temperature changes; contain mercury or alcohol and measure temperature using Celsius.

Scales and spring balance. Scales/electronic balances measure the quantity of a substance; Newton/spring balances measure force by the stretch of a spring.

Gas jar. Used for the collection of gases and for reaction of substances with gas already present.
