Uses Of Common Laboratory Apparatus Flashcards
The ______ doesn’t measure the volume of liquids very accurately. It is usually used as a container for mixing or holding chemicals.
BEAKER
used to measure accurate volume of standard solutions; used in the titration process
BURET
a container which gives only approximate measurements of volume. It is usually used as a
mixing vessel or a container for heating.
ERLENMEYER FLASK
used as a wash bottle and as a container for boiling
liquid solutions
FLORENCE FLASK
is used the measure one specific volume of liquid
(kind of like a volumetric pipet)
VOLUMETRIC FLASK
A ____ is used with filter paper to remove undissolved solids from a liquid mixture. It also can be used to help pour a liquid into a container that has a small opening (for example, a volumetric flask).
GLASS FUNNEL
is a glass container. A mixture of liquids can be
poured into it and allowed to separate.
SEPARATORY FUNNEL
used to measure volumes of liquids
GRADUATED CYLINDER
used to measure volumes of liquids
GRADUATED CYLINDER
are used to measure one amount
only. For example, a 25 mL volumetric pipet is used to measure 25 mL only, and no other amount.
Volumetric pipets
have a lot of lines drawn on it so that you can measure many different amounts.
Graduated pipets
used to guide liquids while pouring into a
container; for stirring purposes
STIRRING ROD
used to guide liquids while pouring into a
container; for stirring purposes
STIRRING ROD
used as a reaction vessel; for heating small volumes of solutions
Test tube
it is used to measure temperature. We use
celsius in the chemistry lab.
THERMOMETER
can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical).
WATCHGLASS
can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical).
WATCHGLASS
A ____ is used to rinse glassware in the chemistry lab. It is NOT used to rinse your eyes!
WASH BOTTLE
The _____ are used to hold small amounts of chemicals during heating at high temperatures, especially if you want to keep oxygen out of the reaction
CRUCIBLE and its COVER
is used as a container for heating, usually when you want to evaporate a liquid from some chemicals
EVAPORATING DISH
is used as a container for heating, usually when you want to evaporate a liquid from some chemicals
EVAPORATING DISH
A ____ has a number of small “wells”. Chemicals are placed into the small wells, and the reaction can be observed as it takes place in the “well”.
SPOT PLATE
used to supply heat
BUNSEN BURNER
BURET CLAMP
used to hold buret in titration setups.
used to support crucibles while heating
CLAY TRIANGLE
used to hold hot crucibles and other
objects
CRUCIBLE TONGS
can be used to hold or pick up many items, but work best as tongs for picking up a hot evaporating dish.
LAB TONGS
are best used to hold a hot beaker.
BEAKER TONGS
are a chemist’s “hot pot holder”. They are used to pick up hot glassware.
HOT HANDS
are a chemist’s “hot pot holder”. They are used to pick up hot glassware.
HOT HANDS
DEFLAGRATING SPOON
used to support heated apparatus
and support funnel in filtration
IRON RING
used to support setup in distillation,
extraction or titration process
IRON STAND
used to weigh substances or objects
PLATFORM BALANCE
used to weigh substances or objects
Analytical balance
used to weigh substances or objects
Analytical balance
used to spoon out solid reagents from reagent bottles
Spatula
used for cleaning test tubes
TEST TUBE BRUSH
used to support heated apparatus
TRIPOD
This all-purpose______ can be used to hold many lab equipment items when it is attached to a ring stand. For example: test tubes, hoses, erlenmeyer flasks, burets.
UTILITY CLAMP
TEST TUBE HOLDER
used to hold test tubes while heating
used for heating and evaporating volatile and flammable substances
WATER BATH
used to sip liquid reagents from reagent bottles with the use of the pipette
ASPIRATOR
used to hold test tubes in place
TEST TUBE RACK
The ____ is the dish, and the____ is the grinder. They are used to crush or
grind up chemicals.
MORTAR; PESTLE
