lab equipment Flashcards
holds solids/liquids that release gas that are unlikely to be splattered if heated/stirred
beaker
holds solids/liquids that release gas that are likely to be splattered if heated/stirred
erlenmeyer flask
used to mix chemicals + it’s thin neck prevents splashing
florence flask
used to measure volume of liquid
graduated cylinder
used when large volumes of gases are produced and must be collected by the displacement of water
gas collecting bottle
thin glass tube that is used to hold small amounts of chemicals/liquid
test tube
used for holding a test tube that’s too hot to handle
test tube holder
used to clean test tubes and graduated cylinder
test tube brush
holds and organizes test tubes in the lab
test tube rack
to close containers to avoid spillage/contamination
rubber stoppers
used to manually stir solutions and can be used to transfer a single drop of solution
glass stir rod
used to transfer a small volume of liquid
medicine dropper
paper. red is used to identify bases, blue is to identify acids
litmus paper
used to pick up small objects
forceps/tweezers
used to transfer one vessel to another
funnel
measures and delivers exact volume of liquid
mohr pupet
has a spout that is used to deliver a wash solution to a specific area. distilled water is the only liquid that should be used.
wash bottle
used to weigh solids that will be transferred to another vessel
weighing boat
used to dispense solid chemicals from their containers
spatula
used to move beakers containing hot liquid
beaker tongs
used to heat non volatile solids and liquids
bunsen burner
used for the heating of stable solid compounds and elements
evaporating dish
used to heat certain solids, particularly metal, to a very high temperature
crucible
used as support for porcelain crucibles when being heated over bunsen burners
clay triangle
used to handle hot crucibles and other objects
crucible tong
provides a surface for semi-micro scale experiments
glass plates
used primarily cut a glass rod
triangular file
safe and convenient way to perform reactions that require a bunsen burner
ringstands
connected to a ring-stand to provide a stable and elevated platform
iron rings
secures test tubes, distillation columns, and burets to the ringstand
utility clamp
sits on the iron ring to provide a place for the beaker to stand
wire gauze
provides a surface for hot beakers so that the beaker does not shatter when it comes in contact with a cold surface
pressed fiber pad
used to light bunsen burners
striker
