Lower Miniscus
What is ebullition
Sudden outburst of the liquid (when heating)
- Decantation
- What do you call the liquid that is being transferred
- separation of liquid from solid
- Supernatant
Test tube
Hold and mix liquids
Wire gauze
Supports a container, such as beaker, on a ring stand during heating
Filter funnel
for filtration
To transfer liquids or fine-grained materials into containers with small openings
Clay triangle
Supports crucible during heating
Crucible
Holds chemicals during heating to very high temperatures
Graduated cylinder
to measure a precise volume of liquid
Beaker
to hold, mix, and heat liquids
Bunsen Burner
Heat source in the absence of flammable materials
For grasping and lifting laboratory items including, hot evaporating dishes, beakers, crucibles, and other laboratory apparatuses
tongs
To transfer solids
Spatula/Scoopula
To prepare solutions of accurate volume

to crush and grind materials
To rinse part of glasswares and add small quantities of water
Wash bottle
for measuring mass
balance
To support laboratory glassware,water bath, etc.
Iron stand
Stirring rod
for stirring and mixing
to hold solids while they are being weighed or to cover a beaker
Watch glass
