lab equipment Flashcards
beaker
beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated
Erlenmeyer Flask
hold liquids that may release gases during a reaction or that are likely to splatter if they are stirred or heated
florence Flask
used for mixing chemicals, neck pervents splash
graduated cylinder
used to measure volumes of liquids
test tudes
small glasses used to store or heat a small amount of chdmical substances
gas collecting bottle
used when large volumes of gases are produced, must be collected by the displacemnt of water
test tube holder
useful when holding a hot test tube
test tube brushes
used to clean test tubes
test tube racks
test tube racks are used for holding and organizing test tubes
rubber stoppers
used to close containers to adviod spillage or contamination
spot plates
used when we want to perform small scale reactions at 1 time
watch glass
used to hold a small amount of solid
medicine dropper
used to transfer a small volume of liquid
litmus paper
red: litmus paper is used to identify bases
blue: used to identify acids
glass stir rod
used to stir solutions, used to transfer a drop of a solution
forceps
used to pick up small objects
funnel
used to help aid the transfer of one liquid from a vessel to another
mohr pipet
measures and delivers exact volumes of liquids
wash bottle
has a spout that delivers a wash solution to a certain area
weighing boat
used to weigh solids that will be transferred to another vessel
spatulas
Used to dispense solid chemicals from their containers
beaker tongs
used to move beakers with hot liquids
bunsen burner
used for the heating of nonvolatile liquids and solids
evaporating dish
used for the heating of stable solid compounds and elements.
crucible
used for heating certain solids, mostly metals to high ttemperatures
clay triangle
used as a support for porcelain crucibles when being heated over a Bunsen burner
crucible tongs
used for hot crucibles, not for picking up beakers
glass plates
provide a surface for semi-micro scale experiments, such as drop reactions and testing acids and bases
triangle file
used to cut glass rod
ringstands and their componets
way to perform reactions that require heating from a bunsen burner
iron rings
connect to a singstand, create a platform
utility clamps
used to secure test tubes
double bruet clamps
used to burets, long graduated tubes used in titration
wire gauze
provides a place to stand a beaker
