Lab Equipment Flashcards
hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Beaker
are used to move beakers containing hot liquids
Beaker tongs
hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.
Erlenmeyer flasks
Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.
Florence Flask
used to measure volumes of liquids.
Graduated Cylinder
useful for holding a test tube which is too hot to handle.
Test Tube Holder
used to clean test tubes and graduated cylinders
Test tube brushes
are for holding and organizing test tubes on the laboratory counter.
After washing flip test tube over on wooden peg to dry.
Test tube racks
are used to close containers to avoid spillage or contamination.
Containers should never be heated when there is a stopper in place.
Rubber Stoppers
are used when we want to perform many small scale reactions at one time.
Spot Plates
is used to manually stir solutions. It can also be used to transfer a single drop of a solution.
Glass Stir Rod
are used to pick up small objects.
Forceps (or tweezers)
is used to aid in the transfer of liquid from one vessel to another.
funnel
used to hold a small amount of solid, such as the product of a reaction.
Watch Glass
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.
Wash Bottle
are used to weigh solids that will be transferred to another vessel.
Weighing Boat
are used for the heating of nonvolatile liquids and solids.
Bunsen burners
are used to light Bunsen burners.
Strikers
is used for the heating of stable solid compounds and elements.
Evaporating Dish
are used for heating certain solids, particularly metals, to very high temperatures.
Crucible
used as a support for porcelein crucibles when being heated over a Bunsen burner.
Clay Triangle
For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers!
Crucible Tongs
Ringstands and their Components
- Ringstand
- Utility Clamps
- Iron Ring
- Wire Gauze
- ## Double Buret Clamps
are a safe and convenient way to perform reactions that require heating using a Bunsen burner
Ringstands
Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand.
Utility clamps
connect to a ringstand and provide a stable, elevated platform for the reaction.
Iron rings
sits on the iron ring to provide a place to stand a beaker.
Wire gauze
used to burets – long graduated tubes used in titration.
Double Buret clamps
are used primarily to cut glass rod, a skill that your instructor will share with you when it becomes useful.
Triangular files
Litmus Paper
Red
Blue
is used to identify bases.
Red litmus paper
is used to identify acids.
Blue litmus paper
We use __________________ when large volumes of gases are produced, and must be collected by the displacement of water.
gas collecting bottles
is used to transfer a small volume of liquid (less than one mL).
On top of each _____________ is a “rubber bulb”
Medicine Dropper
measures and delivers exact volumes of liquids.
Mohr Pipet
provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases.
Glass Plates
are used to dispense solid chemicals from their containers.
Chemicals should never be transferred with your bare hands.
Spatulas
NEVER BACK DOWN NEVWER WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!
NEVER GIVE UP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
