Laboratory Apparatus Flashcards
used for holding various chemicals not for measuring precisely
beakers
-used to precisely measure the volume of liquids or run experiments.
-Read/look from the meniscus at eye level.
-Plastic ring always on top if applicable.
graduated cylinder
-Used to
approximately measure the volume various liquids.
-Useful for mixing by swirling
Erlenmeyer flask
-Used to boil liquids.
-Also used to collect gases, if applicable.
Florence Flask
-Used to prepare precise standard solutions.
-They are only good for 1 specific volume.
Volumetric flask
Used to store, transport, or view reagents such as acids or bases.
Reagent bottle
-Used to close flasks and test tubes.
-The holes allow the insertion of glass tubing, probes, or thermometers as needed by the experiment.
Rubber stoppers
-Used to hold
chemicals while experimenting.
-Not for measuring precisely.
test tubes
Used to hold tubes while experimenting
test tube rack
used to separate liquid based on boiling point
Distillation flask
Used for precisely measuring dispensed liquids
Buret
Holds buret to ring stand.
buret clamp
Base/Pole of set-up for
experimenting.
Ring stand
holds glassware in place for heating or evaporating.
Ring Clamps
-used for cleaning
-must clean before and after use
Test tube brushes
used for carrying or holding hot test tubes
test tube holder
-used for measuring temperature
-use metric
thermometer
used to heat substance
hotplate
-Used to heat substances quickly or if > 400°C is needed.
-Do not use with flammable substances.
Bunsen burner
Used for a variety of things.
Example:
- Connecting Bunsen burner to gas valve stem.
- Connecting glass tubing together.Rubber tubing
Rubber tubing
-Used to absorb and spread the heat of flame.
-Keeps glassware from cracking and breaking.
-Part of ring stand set-up.
Wire Gauze
-Used to hold a crucible in place on a ring stand.
-Also helps absorb and spread heat of flame.
-Part of ring stand set-up.
Clay Triangle
-Used for heating substances
-Can withstand high direct heat
crucible and cover
used to carry crucible
crucible tongs
used to carry beakers
beaker tongs
grind substances into powder or slurry
Mortar and pestle
-Used to scoop chemical powders.
-Not a measuring instrument.
scoopula
used to stir
stirring rods
used to show chemical reaction
watch glass
used to evaporate excessive liquid
evaporating dish
used to separate suspensions (solids from liquids)
centrifuge
Used to precisely measure length
meter stick
used to safely transfer substances to one container to another
funnel
Used to measure out small amounts of liquids for experiments.
dropper and bottle
-Usually contains deionized water
-Handy for rinsing glassware and for dispensing small amounts of dH, for chemical reactions.
wash bottle
Used to protect your eyes from damage
goggles
Used to protect your clothing from damage
apron
Used to accurately measure mass.
digital balance
used to compare the masses of two substances
double pan balance
Used to precisely measure the volume of liquids in small amounts.
pipet pump and bulb
used to collect liquid through the process of capillary action
capillary tubes
-Used to ignite gas from a bunsen burner
-Do not use flint
Striker
-Used to collect samples from colonies (bacteria)
-Also used to test the spectra of chemicals
Inoculating or flame loop
measures the mass of an object
-make certain the balance is calibrated correctly before use
triple beam balance
More precise than the triple beam balance
Centrigram Balance
Disposable pipets used to transfer small amounts of chemicals
-graduated pipets can precisely measure small amounts of chemicals
Berol Pipet
