Lab Apparatus and Equipment Flashcards
B_ a _ _ r holds solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated
Beaker
B _ a k _ _ t _ n _ s are used to move beakers containing hot liquids
Beaker tongs
E _ l _ n _ _ y _ _ _ _ a s _ holds solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated
Erlenmeyer flask
F l _ _ r _ _ c _ f _ a _ _
are rarely used in first year chemistry - used for the mixing chemicals. Narrow neck prevents splash exposure
Florence flask
V _ _ u _ e t _ _ c _ l a _ k is used to know both precisely and accurately the volume of the solution that is being prepared
Volumetric flasks
G r _ _ _ a _ _ d _ _ _ i _ d _ r is used to measure volumes of liquids
Graduated cylinder
S _ p a _ _ t _ _ y f _ n _ e _
is for liquid-liquid extractions, separating a mixture’s components into two solvent phases of different densities.
Separatory funnel
T _ _ t _ _ b _ s is used to hold, mix, or heat small quantities of solid or liquid chemicals
Test tubes
_ e s _ t _ _ e _ o l _ _ r is used for holding a test tube which is too hot to handle
Test tube holder
_e _ t _ u _ e r _ c _s for holding and organizing test tubes. After washing, flip test tube over on rack to dry
Test tube racks
R _ b _ e _ _ t o _ _ e _ s
are close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place
Rubber stoppers

Crucible and cover
_ l a _ t _ _ a n _ _ e is used as a support for porcelain crucibles when being heated over a Bunsen burner
Clay triangle
C _ u _ _ b _ e _ o n _ s is for handling hot crucibles and to pick up other hot objects NOT to be used for picking up beakers
Crucible tongs
_ _ o _ _ _ a n _ supports the iron ring when heating substances or mixtures
Iron stand
_ t i _ _ _ y c _ a m _ _ is used to secure test tubes, distillation columns, and burettes to the ring stand
Utility clamps
I _ o _ _ i n _ _ is used to connect to a ring stand and provide a stable, elevated platform for the reaction
Iron rings
W _ r _ _ a _ _ e sits on the iron ring to provide a place to stand a beaker
Wire gauze
T _ i a _ _ u _ a _ f _ l _ is used to primarily cut glass rod
Triangular file
M _ _ i c _ _ _ _ r _ p _ _ r
is used to transfer a small volume of liquid (less than one mL)
Medicine dropper
M _ _ r _ i p _ _ is used to measure and deliver exact volumes of liquids
Mohr pipet
B _ r e _ _ _ is used in quantitative chemical analysis to measure the volume of a liquid or a gas; used to dispense small volumes of liquid called aliquots, or something gas, with high accuracy
Burette
T _ e _ _ o m _ _ e r measures temperature
Thermometer
D _ s t _ _ l _ _ _ f _ _ s _ is used for the separation and/or purification of liquids or liquid mixtures where the components have different boiling points
Distilling flask
