Lab Equiptment Flashcards
Beaker
Holds solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Erlenmeyer Flask
Holds solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.
Florence Flask
Used for mixing chemicals. Narrow neck prevents splash exposure. (Rarely used in first year of chemistry).
Graduated Cylinder
Used to measure volumes of liquids.
Test Tubes
A thin glass tube closed at one end, used to hold small amounts of material for laboratory testing or experiments.
Test Tube Holders
A tool useful for holding a test tube that is too hot to handle.
Test Tube Brushes
Brushes used to clean test tubes and graduated cylinders. Using a brush too large for the container will cause it to break.
Test Tube Racks
Used for holding and organizing test tubes on the laboratory counter. Do not use plastic racks with hot test tubes.
Watch Glass
Used to hold a small amount of solid, such as the product of a reaction.
Spot Plates
Used to perform many small scale reactions at once. (Used often in Honors Chemistry)
Glass Stir Rod
Used to manually stir solutions. Can also be used to transfer a single drop of a solution.
Forceps
Used to pick up small objects.
Funnel
Used to aid in the transfer of liquid from one vessel to another.
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.
Weighing Boat
Used to weigh solids that will be transferred to another vessel.
