Clinical Laboratory Apparatus Flashcards
(33 cards)
Graduated glass tube with a narrow
outlet, used for delivering a
measured volume of liquid or
measuring the quantity of a gas or
liquid collected or discharged.
BURETTE
A scientific equipment which is used
specifically to hold and secure a
burette on a stand, so that a burette
is fixed and more convenient. Used
to hold the burettes in titration
BURETTE
CLAMP
A laboratory instrument used to
measure out or transfer small
quantities of liquid, in volumes of
milliliters (mL), microliters (μL) from
a reagent bottle.
MEASURING
PIPETTE
A tube designed for measuring or
administering by drops
DROPPING
PIPETTE
An instrument used for measuring
liquid flow when subjected to an
applied force.
VISCOSITY
PIPETTE
A laboratory equipment used in the
distillation process as the tube
collecting the gas distillate so as to
change it into liquid formy
CONDENSER
Is a device that measures
temperature or a temperature
gradient. They are made of metal or
glass.
THERMOMETER
Slender glass used for stirring and
as a guide in directing the flow of
liquids for pouring. It is also used in
decantation.
STIRRING
RODS
Used for holding, mixing, or stirring
hot liquid while in the process of
deflagration.
DEFLAGRATING SPOON
Scissor-like tools, but instead of
having two blades, these tools are
replaced with two pincers or pieces
of metals that concave together.
They are used in holding hot
materials or apparatus
CRUCIBLE TONG
Scissor-like tools, but instead of
having two blades, these tools are
replaced with two pincers or pieces
of metals that concave together.
They are used in holding hot
materials or apparatus
CRUCIBLE TONG
Also known as Clamp fastener- it is
a piece of laboratory apparatus that
is used to secure laboratory clamps,
such as extension-type utility
clamps.
CLAMP
HOLDER
A metal wire device used to hold
and secure the test tubes.
TEST TUBE
HOLDER
A cleaning device used for cleaning
test tubes after usage.
TEST TUBE
BRUSHES
are typically used to
add liquid to an existing system or
instrument. This is typically
necessary for experiments involving
semi-permeable membranes, such
as osmosis and diffusion, where it
can be shown effectively with this
glassware. It is also essential in
separation experiments and
chemical applications.
THISTLE TUBE
a circular concave
piece of glass used in chemistry as
a surface to evaporate a liquid, to
hold solids while being weighed, for heating a small amount of substance and as a cover for a
beaker
WATCH GLASS
are used to contain
liquids during centrifugation, which
separates the sample into its
components by rapidly rotating it
around a fixed axis.
CENTRIFUGE
TUBES
are glassware
containers used for laboratory
testing. They are used for the
evaporation of liquids and solutions
to produce a solid substance or
concentrated solutions. Dishes have
a shallow flat round surface to
promote evaporation.
EVAPORATING
DISH
often used in a
chemistry or biology laboratory, is a
metal tool for cutting a hole in a cork
or rubber stopper to insert glass
tubing.
CORK BORERS
is also known as an
eductor-jet pump ,or a filter pump.
This is a device that is able to
produce a vacuum by using the
venturi effect. In an ______ there
is a fluid (either liquid or gaseous)
that flows through a narrowing tube.
Once the tube starts narrowing, the
fluid’s speed is able to increase.
ASPIRATOR
used to separate immiscible liquids.
When two immiscible liquids are
placed in a ______, two
layers are seen. The denser solvent
will be the bottom layer. Most
halogenated solvents are denser
than water, most non-halogenated
solvents are less dense than water.
SEPARATORY
FUNNEL
are used in a science
lab for heating, combustion, and
sterilization.
ALCOHOL
LAMP
a mesh screen
made of metal wires that are
intertwined to form a grid-like
pattern, and is commonly used in
scientific laboratories to support
glassware during heating, and to
spread the heat evenly through a
flame. It is typically placed on a
support ring or tripod stand and
heated using a Bunsen burner or
other heat source. The grid-like
pattern of the _______ helps to
evenly distribute heat across the
surface of the glassware, which
helps prevent thermal shock and
reduces the risk of cracking or
breaking.
WIRE GAUZE
Laboratory equipment which
comprises a conjoined metal ring
and radially-extending rod. In some
cases, the rod terminates in a screw
clamp for attachment to a retort
stand or other support; in others, the
rod may be attached to a stand by
means of a laboratory clamp holder.
IRON RING
