Lab Equipment Visuals, Spellings, and Uses The Right tool for the job! Dr. Laya Rajendran  Beakers Beakers are used for holding various chemicals. Used for collecting liquids Not for measuring precisely. Sizes vary.  Graduated Cylinder Used to precisely measure the volume of liquids or run experiments. Read from the Loading… 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.  Volumetric Flask Used to prepare precise standard solutions. They are onlyLoading… good for 1 specific volume. Comes in many sizes  Test Tubes and Rack Used to hold chemicals/tubes while experimenting. Not for measuring precisely. Waft! Aim away from faces. Sizes vary. Label tubes.  Buret and Buret Clamp Used for precisely Buret measuring dispensed liquids Holds buret to ring stand. Double buret clamp Single buret clamp  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!! Loading…  Hot Plate Used to heat substances.  Bunsen Burner Used to heat substances quickly or if > 400oC is needed. Do not use with flammable substances.  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.  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.  Watch Glass Used to show chemical reactions.  Evaporating Dish Used to evaporate excess liquids.  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.  Digital Balance Used to accurately measure mass. Only up to 200g in our labs.  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.
