Visuals, Spellings, and Uses
The Right tool for the job!
Beakers
• Beakers are used for holding various chemicals.
• Not for measuring precisely.
• Sizes vary.
Graduated Cylinder
• Used to precisely measure the volume of liquids or run experiments.
• Read from the meniscus at eye level.
• Plastic ring always on top if applicable.
• Sizes vary.
Erlenmeyer Flask
• Used to approximately measure the volume various liquids.
• Useful for mixing by swirling
• Sizes vary.
Florence Flask
• Used to boil liquids.
• Also used to collect gases, if applicable.
• Sizes vary.
Volumetric Flask
• Used to prepare precise standard solutions.
• They are only good for 1 specific volume.
• Comes in many sizes
Reagent Bottle
• Used to store, transport, or view reagents such as acids or bases.
Rubber Stoppers
• Used to close flasks and test tubes.
• The holes allow the insertion of glass tubing, probes, or thermometers as needed by the experiment.
Test Tubes and Rack
• Used to hold chemicals/tubes while experimenting.
• Not for measuring precisely.
• Waft!• Aim away from faces.• Sizes vary.• Label tubes.
Distillation Flask
• Used to separate liquids based on boiling point.
Buret and Buret Clamp• Used for precisely
measuring dispensed liquids
• Holds buret to ring stand.
Double buret clampSingle buret clamp
Buret
Ring Stand and Ring Clamps
• Base/Pole of set-up for experimenting.
• Holds glassware in place for heating or evaporating.
Test Tube Brushes
• Cleaning.
• You must clean tubes before and after you use.
Test Tube Holder
• Used for carrying or holding hot test tubes.
Thermometer
• Measuring temperature.
• Use metric!!
Hot Plate
• Used to heat substances.
Bunsen Burner
• Used to heat substances quickly or if > 400oC is needed.
• Do not use with flammable substances.
Rubber Tubing
• Used for a variety of things.
• Example:– Connecting Bunsen
burner to gas valve stem.
– Connecting glass tubing together.
Wire Mesh or Gauze
• Used to absorb and spread the heat of flame.
• Keeps glassware from cracking and breaking.
• Part of ring stand set-up.
Clay Triangle
• Used to hold a crucible in place on a ring stand.
• Also helps absorb and spread heat of flame.
• Part of ring stand set-up.
Crucible and Cover
• Used for heating substances.
• Can withstand high direct heat.
Crucible Tongs
• Used to carry crucible.
Beaker Tongs
• Used to carry beakers.
Mortar and Pestle
• Used to grind substances into powder or slurry.
Scoopula
• Used to scoop chemical powders.
• Not a measuring instrument.
• Ours do not have handles.
Stirring Rods
• Used to stir substances.
• Clean in between uses.
Striker
• Used to ignite gas from a Bunsen burner.
• Do not waste flint.
Watch Glass
• Used to show chemical reactions.
Evaporating Dish
• Used to evaporate excess liquids.
Centrifuge
• Used to separate suspensions (solids from liquids).
Meter Stick
• Used to precisely measure length.
• 1m = 10dm
• 1m = 100cm
• 1m = 1000mm
Funnel
• Used to safely transfer substances from one container to another.
Dropper and Bottle
• Used to measure out small amounts of liquids for experiments.
Wash Bottle
• Usually contains deionized water.
• Handy for rinsing glassware and for dispensing small amounts of dH2O for chemical reactions.
Goggles and Apron
• Used to protect your eyes and clothing from damage.
• These are a must in lab!!
Inoculating or Flame Loop
• Used to collect samples from colonies (ex. Bacteria)
• Also used to test the spectra of chemicals.
Digital Balance
• Used to accurately measure mass.
• Only up to 200g in our labs.
Triple Beam Balance
• Measures the mass of an object.
• Make certain the balance is calibrated correctly before use.
Double Pan Balance
• Used to compare the masses of two substances.
Centigram Balance
• Used to precisely measure the mass of a substance.
• More precise than the triple beam balance.
Pipet, Pump, and Bulb
• Used to precisely measure the volume of liquids in small amounts.
Berol Pipet
• Disposable pipets used to transfer small amounts of chemicals.
• Graduated pipets can precisely measure small amounts of chemicals.
Capillary Tubes
• Used to collect liquid through the process of capillary action.
