laboratory equipments

• Beaker


  Hold solids or liquids. Very poor accuracy – should only be used to estimate volume
• Beaker Tongs


  Used to move beakers containing hot liquids
• Bunsen Burner


  Used for heating nonvolatile liquids and solids
• Analytical Balance


  Make sure balance is zeroed (reads zero) before beginning. You can do this with the "zero" function
• Crucible and cover


  Used for heating certain solids, particularly metals, to very high temperatures. The cover can be used to contain any smoke particles
• Crucible Tongs


  For handling hot crucibles; also used to pick up other hot objects - NOT to be used for picking up beakers
• Erlenmeyer Flask


  Hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated
• Evaporating Dish


  Used for heating stable solid compounds and elements, as well as for evaporating nonvolatile solutions
• Florence Flask


  Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure
• Forceps


  Used to hold or pick up small objects
• Funnel


  Used to aid in the transfer of liquids from one vessel to another, and will hold filter paper while filtering. It may be glass or plastic
• Graduated Cylinder


  Used to more accurately measure volumes of liquids (probably your best everyday measuring tool) there are three sizes in your desk: 10 mL, 50 mL and 100 mL
• Buret


  Used to very accurately measure volumes of liquids and dispense small measurable amounts of liquids
• Pipet


  Used to very accurately dispense volumes of liquids. We use a pipet bulb or a delivery tube to dispense the liquid. Never use your mouth to draw liquid into the pipet
• Glass Dropper Pipet


  Used to transfer a small volume of liquid, usually one drop at a time
• Disposable Pipet


  Used to transfer a small volume of liquid, usually one drop at a time
• Pipe Stem (Clay) Triangle


  Used as a support for crucibles when being heated over a lab burner. It can also be used to support a funnel when filtering
• Reaction Plates


  (or multi-well plates) are used when we want to perform many small scale reactions at one time. It is like having lots of test tubes available at one time
• Ringstands


  A safe and convenient way to perform reactions that require heating using a lab burner. Never put them in the cabinet if they are too hot to hold as it can cause a fire
• Metal Ring


  Connect to a ringstand, and provide a stable, elevated platform for a beaker to be heated. Will also hold a pipe stem triangle and funnel during filtering
• Test tube/Utility Clamps


  Used to secure test tubes, distillation columns, and burets to the ringstand
• Wire Gauze


  Sits on the iron ring to provide a place to stand a beaker
• Scoopula/Spatula


  Used to transfer solid chemicals. Never insert a spatula directly into a reagent bottle
• Stirring Rod


  Used to: manually stir solutions; assist in pouring liquids; and to transfer a single drop of a solution
• Flint Lighter / Striker


  Used to light lab burners
• Test Tubes


  Used to mix chemicals, and also to heat chemicals. Only heat test tubes that are Pyrex or Kimax
• Rubber Stoppers


  Used to seal a reaction vessel, which could be a flask or a test tube
• Test Tube Brushes


  Used to clean test tubes and graduated cylinders
• Test Tube Racks


  For holding and organizing test tubes on the laboratory counter
• Wash Bottle


  Used to rinse solids from other equipment when trying to conserve (keep all of) the solid—for instance, from the inside of a test tube
• LabQuest and Probes


  Keep probe wires clear of flame and burners
• Mortar & Pestle


  Used to grind solids into fine powders to speed the mixing or reaction process. It is a thicker porcelain that is more heavy duty than the evaporating dish
• Watch Glass


  Used to hold a small amount of solid, such as the product of a reaction. Can also be used as a cover for an evaporating dish or beaker
• Weigh Boat


  Used to weigh solids that will be transferred to another vessel
• Clamp stand


  Used to hold test tubes and other equipment in place. Also known as a ringstand
• Litmus Paper


  Red used to identify bases. Blue is used to identify acids
• thristle tube - to add liquid to an existing system or apparatus.
• burette clamp - which used specifically to hold and secure a burette on a stand,
• aspirator - an apparatus for producing suction or moving or collecting materials by suction.
• CuSO4 - copper sulfate
