									Common Chemistry Lab
    Equipment
 Chemistry Lab Drawer




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




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




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




l Test  Tube Rack and Test Tubes
l Test Tubes are another “primary”
           reaction vessel
Chemistry Lab Drawer




   l Graduated   Cylinder
         Graduated Cylinders
l Use  these to accurately measure liquids in
  lab. Never use beakers to measure.
l The answer on the SOL to this question is
  always GRADUATED CYLINDER.
l 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.
l We  will work with liters (L) and milliliters
  (mL) in this class.
l You should know that 1000 mL = 1L.
l Also know that cubic centimeters (cm3)
  and milliliters (mL) are different names for
  the same amount. So, 1 mL = 1 cm3.
l 1 drop from a dropper is approximately
  0.05 mL. So, 20 drops = 1 mL.

     l Medicine droppers
l We will primarily use plastic,
     disposable droppers.
Chemistry Lab Drawer




   l Test   Tube Holder
Chemistry Lab Drawer




   l Thermometers
Chemistry Lab Table




   l Crucible   Tongs
Chemistry Lab Drawer




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




     l Watch   Glass
Chemistry Lab Drawer




       l GlassFunnel
  l Used with filter paper.
Chemistry Lab Drawer




      lBeakers
Chemistry Lab Drawer




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




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




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




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




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




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




l Flint   Burner Lighter aka Striker
   Chemistry Lab Drawer




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




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




     l Stirring   Rods
Chemistry Lab Drawer




  l Buret on ring stand
   l Used for titrations.
Chemistry Lab Drawer




  lTest   tube brushes
Chemistry Lab Drawer




l Red   and Blue Litmus Paper
Chemistry Lab Drawer




   l Lab   Apron (Folded)
Chemistry Lab Drawer




  l Analytical   Balances
  Chemistry Lab Drawer




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




  l Round   Bottom flask
    Chemistry Lab Drawer




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




l Triangular   file for glass cutting
