Lab Equipment Flashcards
Holds solids or liquids that will not release gasses when reacted or are unlikely to splatter if stirred or heated
Beaker
Hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated
Erlenmeyer Flask
Used to measure volumes of liquids
Graduated Cylinder
Mix, heat and/or hold small quantities of chemicals for assays and laboratory experiments
Test Tubes
Used to clean test tubes and graduated cylinders; Forcing a large one into a small test tube will often break the tube
Test Tube Brushes
For holding and organizing test tubes on the laboratory counter; plastic ones may melt in contact with very hot test tubes
Test Tube Racks
Used when we want to perform many small-scale reactions at one time
Spot Plates
Used to hold a small amount of solid, such as the product of a reaction
Watch Glass
Used to manually stir solutions; it can also be used to transfer a single drop of a solution
Glass Stir Rod
Used to aid in the transfer of liquid from one vessel to another
Funnel
Has a spout that delivers a wash solution to a specific area; distilled water is the only liquid that should be used in this
Wash Bottle
Used to weigh solids that will be transferred to another vessel
Weighing Boat
Used to dispense chemicals from their containers; chemicals should never be transferred with your bare hands
Scoopulas
Used to move beakers containing hot liquids
Beaker Tongs
Used for the heating of nonvolatile liquids and solids
Bunsen Burner
Used for the heating of stable solid compounds and elements
Evaporating Dish
Used as a support for porcelain crucibles when being heated over a Bunsen Burner
Clay Triangle
For handling crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers
Crucible Tongs
A safe and convenient way to perform reactions that require heating using a Bunsen burner
Ring stands
Connect to a ring stand and provide a stable, elevated platform for the reaction
Iron Rings
Used to secure test tubes, distillation columns, and burets to the ring stand
Utility Clamps
Used to burets - long graduated tubes used in titration
Double Buret Clamps
Sits on the iron ring to provide a place to stand a beaker; on older ones, the white material is asbestos
Wire Gauze
Used to light Bunsen burners; the flints on these are expensive, do not operate the striker repeatedly just to see the sparks
Strikers
