Question | Answer |
produces a hot flame used to heat,dehydrate,or sterilize substances in the lab. ours run on natural gas. | bunsen burner |
this dish is used to recover dissolved solids by evaporation. while it can be heated,it should not be used for "strong" heating. | evaporating dish |
used to light a lab burner. not a toy noisemaker during lab. | striker |
will hold small amounts of a substance to be heated and dehydrated. made of porcelain or ceramic,they can withstand high temperatures. | crucible and cover |
used to temporarily hold test tubes for short periods of "gentle" heating. | test tube holder |
wire frame with porcelain supports used for supporting a crucible during heating a substance | clay triangle |
the rounded bottom of the florence flask makes it ideal for boiling liquids. it also makes this flask easy to tip over when sitting on the lab table. | florence flask |
these are used for picking up crucible and crucible covers ONLY. | crucible tongs |
when attached to the ring stand, this is used to support glassware above the lab table. | watch glass |
provides structural support for various attachments that are usually used to hold glassware. | ring stand |
when attached to the ring stand, this is used to support glassware above the lab table. | support ring |
used as a support for beakers when placed across a support ring. | wire gauze |
used to contain reaction solutions. although they usually have a measurement scale on the side, they are not used to make exact measurements. volumes are approximate. | erlenmeyer flask |
used to carry out chemical reactions. to mix solutions in the test tube, swirl it gently. when not in a test tube holder or clamp, put test tubes in a test tube rack. | test tube |
use to make accurate measurements of liquid volumes. the bumper ring on larger cylinders is to prevent breakage if tipped over. | graduated cylinder |
for measuring exact volume measurements of liquids. it has only one graduation line. | volumetric pipette |
used to measure a single, exact volume. to use: fill the flask to the line on the neck to get the volume indicated on the flask. pay attention to the meniscus. | volumetric flask |
dispense exact volumes of liquid. they are used during a process called titration, in which the exact concentration of a substance is determined. | burettes |
used to measure and transfer small, exact volumes by reading the graduations on the side of the pipette. | graduated pipette |
when attached to the ring stand, this is used to hold a large test tube or florence flask above the lab table. | utility clamp |
used to hold and transfer liquids. although they usually have a measurement scale on the side, they are not used to make exact measurements. volumes are approximate. | beaker |
used to transfer solids from their original container to a scale for weighing. | chemical spoon |
used to grind solids into powders. | mortar and pestle |
used in conjunction with a vacuum connection to a water faucet to speed up filtration. | filter flask |
pull liquid into the pipette by turning the dial on the filler. never draw a liquid into a pipette with your mouth. | pipette filler |
used for rinsing solids out of a container when filtering. | wash bottle |
used to close hoses by pinching them together. | hose clamps |
when lined with filter paper, used to filter suspended solids from a liquid. | filter funnel |
