    #Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.
    #Bunsen burners are sources of heat.
    #Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice.
    #Clay triangles are placed on a ring attached to a ring stand as a support for a funnel, crucible, or evaporating dish.
    #Droppers are for addition of liquids drop by drop
    #Erlenmeyer flasks are useful to contain reactions or to hold liquid samples. They are also useful to catch filtrates.
    #Glass funnels are for funneling liquids from one container to another or for filtering when equipped with filter paper.
    #Graduated cylinders are for measurement of an amount of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice.
    #Pipets are used to dispense small quantities of liquids.
    Ring stand with rings or clamps are for holding pieces of glassware in place.
    #Test tubes are for holding small samples or for containing small-scale reactions.
    #Test tube holders are for holding test tubes when tubes should not be touched
    #Tongs are similar in function to forceps but are useful for larger items.
    #Volumetric flasks are used to measure precise volumes of liquid or to make precise dilutions.
    #Wash bottles are used for dispensing small quantities of distilled water.
    #Watch glasses are for holding small samples or for covering beakers or evaporating dishes.
    #Wire gauze on a ring supports beakers to be heated by Bunsen burners

    bunsen burner – used in heating liqiud chemicals.
    thermometer – used in measuring temperatures.
    funnel – used in transpering liquid chemicals in other container.
