consists of a gas inlet, burner tube, air control vent and gas control
provides a safe and convenient way to perform reactions that require heating
using a Bunsen burner
connects to a ring stand and provides a stable, elevated platrom for the
reaction vessels
sits on the iron ring to provide a place to stand a beaker or an Erlenm eyer flask
and spread the heat uniformly on the bottom of the glassware
used for holding and organizing test tubes on the lab counter (be careful as the
plastic ones may melt if they come in contact with very hot test tubes)
used for reacting and heating small amounts of chemicals
used to accurately measure volumes of liquids

has a spout that delivers a wash solution to a specific area (should contain
water ONLY)
used to transfer a small volume of liquid (has a rubber bulb at one end)
used to aid in the transfer of a liquid from one container to another, or the

used to secure test tubes, and Erlenmeyer flasks to the ring stand
used to heat certain solids to very high temperatures
used to support a crucible when it is being heated wtih a Bunsen burner
used to perform many small scale reactions at one time
used to pick up small objects
used to ground up solids into fine powders
used primarily to cut glass tubing
used to protect your eyes during an experiment
used to handle beakers containing hot liquids (they are NOT to be used to
move crucibles)
used to handle hot crucibles or other hot objects (they are NOT to be used to
move beakers)
used to hold a test tube which is too hot to handle
used to dispense solid chemicals from their containers (NEVER use your bare
hands)
used to heat solid compounds and elements
used to hold a small amount of solid or to cover a container in which a reaction
is occurring
used to weigh solids that will be transferred to another container
