APPARATUS AND USES

• Balance – is used to weigh materials in the laboratory
• Beaker – is used to dissolve, mix, and heat liquids in large

  amounts.
• Test tube – is used as a reaction vessel for experiments involving

  small amounts of reactants.
• Adapter – it is a device that connects the condenser and the

  receiving flask in a distillation process.
• Condenser – a device or unit used to condense vapors into liquid.
• Distilling flask – a round bottomed glass flask that is capable of

  holding a liquid to be distilled.
• Burner – is used as a source of heat In the laboratory
• Buret – is a graduated glass tube used in volumetric analysis for

  measuring accurately definite amounts of liquid
• Buret clamp – is used to fasten glassware into place on a ring

  stand.
• Iron stand or ring stand – is used to mount apparatus.
• Tripod – is used to support apparatus which does not have to be

  attached.
• Wire gauze w/ asbestos pad – is used to separate a beaker or

  flask from direct heat of the burner.
• Clay triangle or pipe steam – is used to support the crucible

  while heating.
• Cork borer – used to make a hole in a cork.
• Crucible & cover – is used for high temperature ignition
• Crucible tong – welded steel tools used to lift a hot crucible from

  a furnace or for other items you may not want to handle with your

  hands.
• Test tube holder – it is used to support the test tube.
• Dropper – is used to transfer small amounts of liquid. It is also

  used for addition of liquids drop by drop.
• Pasteur pipette, or dropper- is a device used to transfer small

  quantities of liquids. They are used in the laboratory and also to

  dispense small amounts of liquid medicines.
• Erlenmeyer flask – container used as a reaction vessel and

  used for titration. It is also useful to catch filtrates.
• Round bottom flask or erlenmeyer bulbs – It is a type of flasks

  having spherical bottoms used as laboratory glassware mostly for

  chemical or biochemical work. It allows more uniform heating and

  / or boiling of liquid.
• Evaporating dish – is used to evaporate a liquid from a solution

  leaving a residue.
• Watch glass – is used for spontaneous evaporation of liquids

  and as a container for weighing
• Funnel – lined with filter paper, is used to facilitate the

  introduction of liquid into narrow-mouthed containers and prevent

  spilling.
• Glass rod or stirring rod – it is used for stirring or mixing

  chemicals.
• Graduated cylinder – glassware calibrated in the Metric System

  and is used to measure volume of liquid samples. It should not be

  used as a reaction vessel.
• Pipet – is used to transfer accurately varying volumes of liquid

  samples.
• Aspirator – a device for removing liquids or gases by suction,

  especially an instrument that uses suction to remove substances.
• Ignition tube – a laboratory tube used much in the same way as

  a boiling tube except not being as large and thick walled. It is

  primarily used to hold small quantities of substance for direct

  heating by a Bunsen burner or other heat source.
• Iron clamp – a piece of laboratory equipment used to hold

  things and is placed in an iron stand to elevate other equipment.
• Iron ring – is mounted on an iron stand to support beakers and

  flasks.
• Mortar and pestle – is used to grind solids into powder form.
• Spot plate, test plate or test tablet – a ceramic plate with

  small dwells or depression bulb into it, often used for

  quantitative analysis.
• Spatula – is used to remove or scoop out solids from the

  container.
• Thermometer – is used to measure temperature.
• Test tube brush – it is a brush that is long and narrow to

  clean the inside of glassware, in particular test tubes.
• Test tube holder – it is used to support the test tube.
• Test tube rack – to hold test tubes upright to keep them from

  spilling.
• Volumetric flask – is used to dilute and prepare exact volumes

  of solution.
• Wash bottle – is a squeeze bottle with a nozzle, used to rinse

  various pieces of laboratory glassware, such as test tubes and

  round bottom flasks.
