   HI this are the laboratory apparatuses you asked:
   
   Beaker - a liquid-measuring container
   clay triangle - a wire frame with porcelain used to support a crucible
   wire gauze - used to spread heat of a burner flame
   test tube - used as holder of small amount of solution
   forceps - holds or pick up small objects
   graduated cylinder - measures approximate volume of liquids
   graduated pipette - measures solution volumes
   condenser - used in distillation
   crucible - used to heat a small amount of a solid substance at a very high temperature
   funnel - used to transfer solids and liquids without spilling
   thermometer - measures temperature
   balance - measures mass of material
   pH meter - measures acidity of solutions
   centrifuge - separates materials of varying density
   pipette - used to transfer measured substances into another vessel
   droppers - for addition of liquids, drop by drop
   glass funnels - for funneling liquids from one container to another, or for filtering when equipped with filter paper.
   Graduated cylinders - for measurement of an amount of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice.
   Ring stand (with rings or clamps) - for holding pieces of glassware in place.
   Test tubes - for holding small samples or for containing small-scale reactions
   test-tube holders - for holding test tubes when tubes should not be touched
   tongs - similar function to forceps, but are useful for larger items
   volumetric flasks - to measure precise volumes of liquid or to make precise dilutions.
   Wash bottles - for dispensing small quantities of distilled water.
   Watch glasses - for holding small samples or for covering beakers or evaporating dishes.
   Wire gauze on a ring - supports beakers to be heated by Bunsen burners

    The Laboratory Apparatus includes beakers, microscopes, tweezers, hot plates, lasers, volt meters, test tubes, Erlenmeyer flasks, thermometers, test tube racks, Bunsen burners, crucibles, tripods and more.
    
    They are used to measure, observe and gather data for experiments, as well as to safely perform reactions and to heat things. More advanced laboratory equipment includes items such as spectrometers, centrifuges and chromatographs.
    
    The description and some of their uses are follows:
    1. beaker - a liquid-measuring container
    2. burette - measures volume of solution
    3. clay triangle - a wire frame with porcelain used to support a crucible
    4. wire gauze - used to spread heat of a burner flame
    5. test tube - used as holder of small amount of solution
    6. forceps - holds or pick up small objects
    7. graduated cylinder - measures approximate volume of liquids
    8. graduated pipette - measures solution volumes
    9. condenser - used in distillation
    10. crucible - used to heat a small amount of a solid substance at a very high temperature
    11. funnel - used to transfer solids and liquids without spilling
    12. thermometer - measures temperature
    13. balance - measures mass of material
    14. pH meter - measures acidity of solutions
    15. centrifuge - separates materials of varying density
