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.
Spatula/Scoopula
Used to dispense solid chemicals from their containers. Chemicals should never be transferred with bare hands.
Bunsen Burner
Used for the heating on nonvolatile liquids and solids.
Evaporating Dish
Used for the heating of stable solid compounds and elements.
Beaker Tongs
Used to move beakers containing hot liquids.
Crucible
Used for heating certain solids, particularly metals, to very high temps.
Clay Triangle
Used as a support for porcelain crucibles when being heated over a Bunsen burner.
Crucible Tongs
For handling hot crucibles, or other hot objects. Not for pickin up beakers.
Glass Plates
Provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases.
Ringstand
Safe and convenient way to perform reactions that require heating using Bunsen burner.
Iron Rings
Connect to ringstand and provide a stable, elevated platform for the reaction.
Utility Clamps
Used to secure test tubes, distillation columns, and burets to the ringstand.
Double Buret Clamps
Used to burets-long graduated tubes used in titration.
Wire Gauze
Sits on iron ring to provide a place to stand a beaker. On old gauze, white material is asbestos.
Strikers
Used to light Bunsen burners. Do not operate unless necessary.
