    Equipment
 Chemistry Lab Drawer




                Well Plate
 Used for “small scale” reactions, where
   you are only using drops of solutions.
  Chemistry Lab Drawer




     Micro Spatula and Scoopula
 Used for measuring small amounts of
              chemicals.
          Scoops and Spoons
 Never   stick these directly into a bottle
  of chemicals.
 You can contaminate the entire
  bottle.
 This means that I will either have to
  throw it away, or your lab results
  could be affected.
   Chemistry Lab Drawer




 Wash bottle. Use this for “rinsing”
 chemicals into your reaction vessel.
Chemistry Lab Drawer




 Test  Tube Rack and Test Tubes
 Test Tubes are another “primary”
           reaction vessel

    Graduated   Cylinder
         Graduated Cylinders
 Use these to accurately measure liquids in
  lab. Never use beakers to measure.
 The answer on the SOL to this question is
  always GRADUATED CYLINDER.
 Accurate to within ± 0.05 ml. (This is ½
  of the smallest division line on the
  cylinder.) Scientists call this the
  “uncertainty” of the measurement.
                 Volumes.
 We will work with liters (L) and milliliters
  (mL) in this class.
 You should know that 1000 mL = 1L.
 Also know that cubic centimeters (cm3)
  and milliliters (mL) are different names for
  the same amount. So, 1 mL = 1 cm3.
 1 drop from a dropper is approximately
  0.05 mL. So, 20 drops = 1 mL.

      Medicine droppers
 We will primarily use plastic,
     disposable droppers.

    Thermometers
Chemistry Lab Table




    Crucible   Tongs
Chemistry Lab Drawer




           Crucible and Lid
       Used for STRONG Heating
Chemistry Lab Drawer




      Watch   Glass
Chemistry Lab Drawer




        GlassFunnel
   Used with filter paper.
Chemistry Lab Drawer




      Beakers
Chemistry Lab Drawer




            Evaporating Dish
 Used for GENTLE heating or NO heating
 Chemistry Lab Drawer




   Wire Triangle with Porcelain
 Use this when heating crucibles.
  Chemistry Lab Drawer




    Ring Stand and Clamps
 Ring Clamps and Utility Clamps
      Chemistry Lab Drawer




   Wire  Gauze with Ceramic Center
 Use this for heating beakers or flasks.
 Chemistry Lab Drawer




         Erlenmeyer  Flask
 Used as a reaction “vessel” in lab.
               Swirl
Chemistry Lab Drawer




    Bunsen   Burner
        Bunsen Burner Safety
 1. Never walk away from a lit burner.
 2. Never leave the gas turned on while
  the burner is NOT lit.
 3. Never leave a test tube in the flame
  while heating.
 4. Never point a test tube at someone
  else while heating.
 Chemistry Lab Drawer




 Flint   Burner Lighter aka Striker
   Chemistry Lab Drawer




      Pipetsand Pipet bulb
 NEVER use your mouth to pipet.
                   Pipets
 Used for transferring solutions to a
  reaction vessel. Transfer pipets are used
  when accuracy isn’t absolutely necessary.
 Volumetric pipets are calibrated to deliver
  an exact amount. Used when that is an
  important factor in your experiment.
Chemistry Lab Drawer




    Volumetric   flasks
          Volumetric Flasks
 Used for making very accurate
  concentrations of solutions.
 Beakers/Flasks—accurate to about 5%
  (50,000 ppm)
 Graduated cylinder—accurate to about 1%
  (10,000 ppm)
 Volumetric Flasks—accurate about 0.04%
  (400 ppm)

   Buret on ring stand
    Used for titrations.

   Analytical   Balances
  Chemistry Lab Drawer




 Desiccator.   Used for cooling
crucibles in a “dry” environment.
Chemistry Lab Drawer




   Round   Bottom flask
    Chemistry Lab Drawer




 Mortarand Pestle. Used for grinding
       up solids or mixing solids.
  Chemistry Lab Drawer




 Triangular   file for glass cutting
