CHEMLAB 1 LAB EQUIP Flashcards
A glassware used for stirring, mixing, and heating liquids.
beaker
Glassware used to heat, mix, and
store liquids. The narrow neck
facilitates mixing without spilling
the contents.
Erlenmeyer Flask
Measures an exact volume of
liquid. It is used to prepare
solutions and to make precise
dilution
Volumetric Flask
Accurately measures the volume of liquids
Graduated Cylinder
Accurately delivers variable
volumes of liquid. A stopcock is
turned to control the amount of
liquid being released. Markings are
found on the length of the tube
that indicates the volume of the
liquid present.
Burette
Measure and transfer an exact
volume of liquid. It is ideal in performing serial dilutions
Serological Pipette
Produces an open flame for heating purposes
Alcohol
Lamp
Used as a heat source during
experiment. It has a knob to adjust
the amount of gas flow and a
rotating collar that controls airflow
Bunsen
Burner
Has a wingtop/fishtail that is
placed in its mouth to spread the
flame
Tirril Burner
Used for indirect heating of
substances in beakers and flasks
Hot Plate
and Water
Bath
Used for scraping or transferring a
small amount of solids
Spatula
Transfers liquids into containers
with small openings. It is also used during filtration
Glass Funnel
A small glass tube used for handling or heating small amounts of substances.
Test Tube
Used to observe multiple reactions at the same time.
Spot Plate
Used as a surface for evaporating
liquid or holding solids.
It is also used as a cover for
beakers.
Watch Glass
A vessel used to hear and consequently evaporate liquids.
Evaporating dish
Provides support for other equipment and a means of raising equipment above the working surface.
Iron ring
Attached to the iron stand to support the flask or funnel in an upright position.
Iron ring
Used to secure equipment to a supporting stand
Iron clamp
Secures an extension type utility
clamp equipment to a support
stand or ring stand
Clamp Holder
Placed on an iron ring attached to
an iron stand as a support for a
funnel, crucible, or an evaporating
dish
Clay triangle
Used for grasping and lifting
vessels
Tongs
Used to hold test tubes especially
during heating
Test Tube
Holder
Used to cool and condense hot
vapors from a heated solution
Condenser
Tube
Used with a pipette to aspirate
liquid
Aspirator
Bulb
Cylindrical filtering funnel during
pressurized filtering procedures
Buchner
Funnel
Measures the relative conductivity
of different chemicals and
solutions.
Conductivity
Apparatus
Used for heating chemicals at high
temperatures
Crucible and
Cover
Used to mix, spread, and lift
chemicals
Wooden
Spatula
Used to crush solid chemicals into
a fine powder
Mortar
(Bowl) and
Pestle
Used for liquid-liquid extractions to
separate the components of
mixtures of different densities
Separation
Funnel
Used to clean different glassware
in the lab
Test Tube
Brush
Used in collecting gas through the
water displacement method
Also known as Suction flask or
Side-arm flask
Büchner
Flask
Used as a container of the solution
to be distilled in the distillation
process
Distilling
Flask
Used to store chemicals in liquid or
powder form
Reagent
Bottles
Used to transfer small amounts of
reagents/liquid
Pasteur
Pipette
Used in titrations to measure
precisely how much liquid is used
Acid = Stopcock; Base = Pinch
cock
Burettes
Acid and
Base
Used as a container for dry
chemicals prior to weighing
Weighing
Boat
Used for supporting the clay
triangle and container to be
heated
tripod
Used as a passage of the gas that
condenses to liquid
Adapter
Used for stirring chemicals
Stirring Rod
Used in direct heating of small
amounts of chemicals
Deflagrating
Spoon
Used to hold burettes in place
during titration
Burette
Clamp
Used to add liquid to an existing
system of apparatus
Thistle Tube
Used for collecting gases, such as
hydrogen, oxygen and nitrogen
Water
Trough
Measures hydrogen-ion activity in
water-based solutions; expressed
in pH
pH Meter
Ventilation system in the
laboratory
Fume Hood
Used to measure the mass of an
object
Usual maximum capacity is 610g
Triple Beam
Balance
Measures mass at high degree of
precision
Readability: 0.00001g to 220g
Analytical
Balance
most common measuring equipment in the laboratory
chemicals = 220g
Top Loading balance
Used to isolate a target compound
A separatory funnel is anchored to an iron stand
with a beaker to collect the isolate
Extraction
Conversion between the solid and gaseous
phases, with no intermediate phase
Evaporating dish which is attached and sealed
with an inverted glass funnel
Sublimation
Uses Acid and Base burette
It is the slow addition of one solution of a known
concentration (titrant) to a known volume of
another solution of unknown concentration
until the reaction reaches Neutralization
To assess the concentration of an analyte that
has been detected
Titration
A liquid is converted to a vapor, which is then
condensed back into a liquid
Distillation
Heat directly; An evaporating dish is placed,
supported by a clay triangle, on a tripod on top
of an open flame
Evaporation (Direct)
Steam evaporation
Evaporation (Indirect)
Its purpose is to separate solid from liquid via filter medium
Filtration
The volume of water that the gas displaced can be used to calculate its volume
Gas collection
