    Names and Uses
           Why Learn This?
 Lab  equipment should only be used for its
  intended purpose.
 In order to do labs safely, you need to know
  equipment names to get set up.
 So you can impress others with your vast
  chemistry knowledge.
                      Tongs
 Used   to handle hot
  items.
 Are specialized to
  reduce the chance of
  dropping something.
 Types include: beaker,
  test tube, and crucible.
          Hot Hand/Hot Mitts
 Used  to handle hot
  objects.
 Remember hot and
  cold glass an metal
  looks the same - treat
  everything as if it is
  HOT!!
                    Beakers
 Beakers   come in many
  sizes.
 Can be used for
  heating if they are
  PYREX.
 Measurements on
  beakers are only
  approximate.
            Erlenmeyer Flask
 Used  to hold liquids.
 Triangular shape with
  a small opening helps
  prevent splatters when
  heating.
 Only use PYREX
  flasks for heating.
              Florence Flask
 This kind of flask
  usually just holds
  liquids
 The small opening
  makes it easy to pour.
 Volumetric flasks
  have an etched line so
  you can measure
  accurately.
              Test Tubes
 Once   again there
  are many different
  sizes.
 Used to contain or
  react small amounts
  of chemicals.
 Cleaned with a test
  tube brush.
         Graduated Cylinders
 Come   in various
  sizes.
 Used to accurately
  measure liquids.
 Make sure the collar
  is pushed up towards
  the top so it won’t
  break if it gets
  knocked over.
           Heating Things Up
 You  use several pieces
  of equipment to safely
  heat things.
 These include: bunsen
  burners, iron rings,
  wire gauze, clay or
  wire triangles, and
  clamps.

                 Hot Plates
 Hot  plates are less
  dangerous than an
  open flame.
 Some have automatic
  stirrers.
         Strikers and Matches
A   striker is a device
  used to light a
  burner.
 We will use
  strikers, NOT
  matches to light
  fires.
     Crucibles and Evaporating
               Dishes
 Used  to dry things out
  either over a flame, on
  a hot plate, or in an
  oven.
 Crucibles have lids to
  prevent splatter.
                   Balance
 The  balances we use
  are electronic.
 Accuracy is very
  important when you
  measure out
  chemicals.
 The tare button sets
  the balance to zero.
         Spatulas and Spoons
 Used  to transfer
  chemicals from the
  bulk container to the
  balance for measuring.
 Always use a separate
  spatula for each
  chemical.
            Thermometers
 Use  alcohol
  thermometers if
  possible.
 Check to make sure
  the column doesn’t
  have gaps
 NEVER rest a
  thermometer in
  heating glassware.
                    Burets
 Burets  are very
  accurate devices
  used to measure
  liquids.
 They have a device
  called a stopcock at
  the bottom.
    Miscellaneous Equipment
 Othersmall pieces
 you might use
 during a lab
 include: forceps,
 microplates, test
 tube racks,
 droppers and
 stoppers.
Now you know
your chemistry lab
equipment.
