CHE 011: AnaChem

• Test tube


  To hold, heat, or mix substances used in experimentation
• Burette


  Used in quantitative chemical analysis to measure the volume of a liquid or gas, used exclusively for the titration process
• Clay triangle


  A wire and ceramic triangle used to support a crucible while it is heated over a Bunsen burner, other name is pipe stem triangle
• Beaker


  A cylindrical glass or plastic vessel used for holding liquids
• Medicine dropper


  Used to pour liquids into solutions or onto surfaces as well as to move liquids from one location to another
• Cork


  A useful material to stop test tubes and flasks, also known as a stopper or bung, partially inserted inside a container to form a seal
• Evaporating dish


  Used to heat liquids over a flame so that they evaporate, leaving a solid residue
• Wire gauze


  Placed on the support ring that is attached to the retort stand between a burner and glassware, or placed on a tripod to support beakers, flasks, or other glassware to protect it during heating, other name: wire mesh
• Reagent bottle


  Used in labs to store chemicals in liquid or powder form in cabinets or on shelves, other names: Media bottles or Graduated bottles
• Alcohol lamp


  Used for heating, sterilization, and combustion in a laboratory
• Iron stand with iron ring

  A ring stand or iron stand is used to provide support for other equipment and a means of raising equipment above the work surface, an iron ring is used to support flasks or funnels upright in a stand
• Funnel


  Used to channel liquid or fine-grained substances into containers with a small opening
• Bunsen burner


  Used to heat substances, to combust substances, and to sterilize objects on high heat
• Triple beam balance


  Used to measure the mass (how much stuff is inside something) of an object that is placed on the pan (flat stainless steel surface)
• Crucible and cover


  A crucible is a cup-shaped piece of laboratory equipment used to contain chemical compounds when heating them to very high temperatures, crucible covers are designed to fit snugly on top of the crucible, helping to contain the substance and reduce the risk of spillage or evaporation
• Water bath


  Used to incubate samples in water at a constant temperature over a long period of time, utilizations include warming of reagents, melting of substrates or incubation of cell cultures, also used to enable certain chemical reactions to occur at high temperatures, preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition
• Test tube holder


  Used for holding a test tube in place
• Stirring rod


  Used for mixing liquids, or solids and liquids
• Watch glass


  A circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker
• Erlenmeyer flask


  Used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes
• Florence flask


  Used as a container to hold solutions of chemicals, other name: Boiling flask
• Thermometer


  An instrument that measures temperature
• Volumetric flask


  Used for measuring accurate volumes of liquid materials for laboratory experiments
• The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin
• Crucible tong


  Used to lift a hot crucible from a furnace or for other items which cannot be handled with bare hands
