Lab Equipment Flashcards
Beaker
Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Erlenmeyer Flask
Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.
Graduated Cylinder
A graduated cylinder is used to measure volumes of liquids.
Test Tube Brushes
Test tube brushes are used to clean test tubes and graduated cylinders.
Forcing a large brush into a small test tube will often break the tube.
Test Tube Racks
Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes.
Spot Plates
Spot plates are used when we want to perform many small scale reactions at one time.
Watch Glass
A watch glass is used to hold a small amount of solid, such as the product of a reaction.
Glass Stir Rod
A Glass Stir rod is used to manually stir solutions. It can also be used to transfer a single drop of solution.
Funnel
A funnel is used to aid in the transfer of liquid from one vessel to another.
Wash Bottle
A wash bottle has a spout that delivers a wash solution to a specific area. Distilled water is the only liquid that should be used in a wash bottle.
scoopula
used to dispense solid chemicals from their containers.
Beaker tongs
Used to move beakers containing hot liquids
Bunsen Burner
used for the heating of nonvolatile liquids or solids
Evaporating Dish
Used for the heating of stable solid compounds and elements
Clay triangle
Used as a support for porcelain crucibles when being heated over Bunsen burner.
