Science Equipment Flashcards
Beaker
Holds solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Beaker Tongs
To move beakers containing hot liquids.
Erlenmeyer Flask
Erlenmeyer flasks hod solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.
Florence Flask
Mixing of chemicals. Narrow neck prevents splash exposure.
Graduated Cylinder
Measure volumes of liquids.
Test Tube Brushes
Clean test tubes and graduated cylinders.
Test Tube Racks
Holding and organizing test tubes on the laboratory counter.
Rubber Stoppers
Close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place.
Spot Plates
Want to perform many small scale reactions at one time.
Glass Stir Rod
Manually stir solutions. It can also be used to transfer a single drop of a solution.
Forceps/ Tweezers
Used to pick up small objects.
Funnel
Aid in the transfer of liquid from one vessel to another.
Watch Glass
Hold a small amount of solid, such as the product of a reaction.
Wash Bottle
Ha 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.
Bunsen Burner
Used for the heating of nonvolatile liquids and solids.
Strikers
Used to light BUnsen burners.
Evaporating Dish
Used for the heating of stable solid compounds and elements.
Crucible
Used for heating certain solids, particularly metals, to very high temperatures.
Clay Triangle
Used as a support for porcelain crucibles when being heated over a Bunsen burner.
Crucible Tongs
For handling hot crucibles; also used to pick up other hot objects. (Not beakers)
Ringstands
A safe and convenient way to perform reactions that require heating using a Bunsen burner.
Iron Ring
Connect to a ringstand and provide a stable, elevated platform for the reaction.
Wire Gauze
Sits on the iron Ring to provide a place to stand a beaker.
Double Buret Clamp
Used to burets- long graduated tubes used in titration.
Triangular File
Used primarily to cut glass rod.
Litmus Paper
Red litmus paper is used to identify bases.
Blue litmus paper is used to identify acids.
Gas Collecting Bottle
Use when large volumes of gases are produced, and must be collected by the displacement of water.
Medicine/Eye Dropper
Used to transfer a small volume of liquid (less than one ml).
Mohr Pipet
Measures and delivers exact volumes of liquids.
Glass Plates
Provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases.
Spatulas
Used to dispense solid chemicals from their containers.
