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
Florence flask
Rarely used in first year of chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.
Graduated Cylinder
A graduated cylinder is used to measure volumes of liquids
Gas Collection Bottle
We use gas collection bottles when large volumes of gases are produced, and must be collected by the displacement of water.
Test Tube Holder
A test tube holder is useful for holding a test tube which is too hot to handle
Test Tube Brushes
Test tube brushes are used to clean test tubes and graduated cylinders.
Test Tube Racks
Test tube racks are for holding and organizing test tubes on the laboratory counter.
Rubber Stoppers
Rubber stoppers are used to close containers to avoid spillage or contamination.
Spot Plates
Spot plates are used when we want to perform many small 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.
Medicine Dropper
A medicine dropper is used to transfer a small volume of a liquid
Forceps
Forceps are used to pick up small objects
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.
Weighing Boat
Weighing boats are used to weigh solids that will be transferred to another vessel.
Spatulas
Spatulas are used to dispense solid chemicals from their containers.
Beaker Tongs
Beaker tongs are used to move beakers that have hot liquids.
Bunsen Burner
Bunsen burners are used for the heating of nonvolatile liquids and solids.
Evaporating Dish
The evaporating dish is used for the heating of stabile solid compounds and elements.
Crucible
Crucibles are used for heating certain solids.
Clay Triangle
Clay triangle is used as a support for porcelain crucibles when being heated over a Bunsen burner.
Crucible Tongs
Crucible tongs are used for handling hot crucibles.
Glass Plates
Glass plates provide a surface for semi-micro scale experiments.
Ringstands
Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.
Iron Rings
Iron rings connect to a ring stand and provide a stable, elevated platform for the reaction.
Utility Clamps
Utility clamps are used to secure test tubes.
Wire Gauze
Wire gauze sits on the iron ring to provide a place to stand a beaker.
