Lab Equipment 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 clamp Single 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 > 400 o C 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 dH 2 O 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.
Lab Equipment. Balance Digital Digital Triple beam Triple beam Measures mass Measures mass Unit is a gram Unit is a gram.
Lab Equipment. Familiarize yourself with the following: 1. Know the names of the individual pieces of lab equipment. 2. Know the use of each piece. Note:
Lab Equipment. Beaker Beakers hold solids or liquids that are unlikely to splatter if heated or stirred. Measures Volume.
