You are probably already familiar with much of the labware that is used in biology. Let's quickly review the basic labware.

Directions: Click on the blanks to see what the best use is for the pictured lab equipment and when not to use this equipment.

Equipment	Picture	Best Use	When Not to Use
Beaker			Heating, mixing, pouring liquids		Precise measurement of liquid volume
Graduated cylinder			Precise measurement of liquids. The smaller the increment of measurement (ex: .5ml vs 1 ml), the greater precision. Also used to determine density of small, and/or irregular objects.		Heating, mixing liquids
Erlenmeyer flask			Mixing, heating, temporary storage of liquids		Precise measurement of volume
Test tubes in rack			Mixing, heating, temporary storage of small amounts of chemicals		Precise measurement of volume, testing large amounts of material
Dropper bottle			With pipette, used to transfer small amounts of liquid to avoid contamination of original liquid source		Very large or very precise transfers of liquid
Electronic balance			Precise measurement of mass. Used with massing paper or boat to protect balance pan surface.		Masses beyond given range of balance. Note: Tare (return to zero) with massing paper/boat before adding chemical.
Incubator			Gently warming bacterial cultures		Sterilizing equipment

In your notes, draw or explain the differences between a beaker, flask, and graduated cylinder uses. List how they are alike.
