									Common Chemistry Lab
    Equipment
 Chemistry Lab Drawer




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




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




   lTest Tube Holder
 Chemistry Lab Drawer




       lErlenmeyer Flask
lUsed as a reaction “vessel” in lab.
             lSwirl
Chemistry Lab Drawer




      lBeakers
Chemistry Lab Drawer
       lMicro Spatula and Scoopula
       lUsed for measuring small
        amounts of chemicals.
       lNever stick these directly
        into a bottle of chemicals.
       lYou can contaminate the
        entire bottle.
   Chemistry Lab Drawer




lWash bottle. Use this for “rinsing”
 chemicals into your reaction vessel.

       lGraduated Cylinder
     lUse these to accurately
      measure liquids in lab.
      Never use beakers to
      measure.
     lThe answer on the SOL is
      always GRADUATED
      CYLINDER.
                 Volumes.
lWe will work with liters (L) and milliliters
 (mL) in this class.
l1000 mL = 1L.
lCubic centimeters (cm3) and milliliters
 (mL) are different names for the same
 amount. 1 mL = 1 cm3.
l1 drop from a dropper is approximately
 0.05 mL. So, 20 drops = 1 mL.

          lCrucible and Lid

             lUsed for
              STRONG
              Heating
Chemistry Lab Table




      lTongs

 lWire Triangle with Porcelain
lUse this when heating crucibles.
Chemistry Lab Drawer
           lEvaporating
               Dish

             lUsed for
           GENTLE heating
            or NO heating
Chemistry Lab Drawer




     lWatch Glass
Chemistry Lab Drawer




     lGlass Funnel
  lUsed with filter paper.
  Chemistry Lab Drawer




   lRing Stand and Clamps
lRing Clamps and Utility Clamps
Chemistry Lab Drawer




   lBunsen Burner
       Bunsen Burner Safety
l1. Never walk away from a lit burner.
l2. Never leave the gas turned on while
 the burner is NOT lit.
l3. Never leave a test tube in the flame
 while heating.
l4. Never point a test tube at someone
 else while heating.
      Chemistry Lab Drawer




  lWire Gauze with Ceramic Center
lUse this for heating beakers or flasks.
   Chemistry Lab Drawer




    lPipets and Pipet bulb
lNEVER use your mouth to pipet.
Chemistry Lab Drawer




   lVolumetric flasks
         Volumetric Flasks
lUsed for making very accurate
 concentrations of solutions.
lBeakers/Flasks—accurate to about 5%
 (50,000 ppm)
lGraduated cylinder—accurate to about 1%
 (10,000 ppm)
lVolumetric Flasks—accurate about 0.04%
 (400 ppm)
Chemistry Lab Drawer




  lBuret on ring stand
  lUsed for titrations.
Chemistry Lab Drawer




     lStirring Rods
Chemistry Lab Drawer




  lLab Apron (Folded)
    Chemistry Lab Drawer




lMortar and Pestle. Used for grinding
      up solids or mixing solids.
