spatula
3 types of spatula
elongated
stainless
porcelain
simple container for liquids, very commonly used in laboratories
beaker
used to accurately measure volumes of chemicals for use in reactions
graduated cylinder
used to target liquids into any container so they will not be lost or spilled.
glass funnel
used in suction filtration.
Buchner funnel
used mainly for cleaning test tubes
test tube brush
A clear, cylindrical glass tube usually open at one end and rounded at the other, used in laboratory experimentation
test tube
Used to hold test tubes while reactions happen in them or while they are not needed.
test tube holder
Used to hold items being heated.
iron ring
can be used so that items may be placed above the lab table for heating by bunsen burners or other items.
clamps or ring
used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker.
watch glass
used to hold solids when being weighed or transported.
watch glass
used to heat and evaporate liquids.
evaporating dish
Used to hold glasswares when they are hot and untouchable
tongs or holder
three- legged platform used to support flasks and beakers.
tripod
used to hold crucibles when they are being heated.
clay triangle
placed on top of the tripod to provide a flat base for glassware.
wire gauge
piece of laboratory equipment used to hold things and is placed in an iron stand to elevate other equipment
iron clamp
used by chemists to add liquid to an existing system of apparatus.
thistle tube
used to incubate samples in water at a constant temperature over a long period of time
water bath
laboratory equipment made from a container filled with heated water
water bath
generally used to heat glassware or its contents.
hot plates
Some hot plates also contain a__, allowing the heated liquid to be stirred automatically.
magnetic stirrer
Used to produce an open flame
alcohol lamp
are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available.
alcohol lamp
a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.
bunsen burner
spreads out the heat in the Bunsen burner over a large area
wingtop or fishtail
Used to bend glass in glass manipulation process.
fishtail
is an air and gas device much like the Bunsen, but with extra adjustments that provide for better temperature control and flame size
tirril burner
Has a gas regulator
tirril burner
A laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion.
meker-fisher burner
It is used when laboratory work requires a hotter flame than produced by a Bunsen burner.
meker fisher burner
Used for mixing liquids or solids and liquids
stirring rod
is used to connect other pieces of lab equipment.
glass tubing
It can be cut, bent and stretched for a variety of uses.
glass tubing
often connected to a condenser, which is a laboratory tool used in the process of distillation.
rubber tubing
helps cool water to flow in and out of the condenser and helps the heated water vapor in the condenser return to its liquid state.
rubber tubing
Used in a distillation set-up
adapter
It connects to the lower end of the condenser and serves to direct the distilled liquid into the receiving flask.
adapter
Used to take temperature of solids, liquids, and gases.
thermometer
also known as droppers or eye droppers, are used to transfer small quantities of liquids.
pasteur pipettes
They are usually glass tubes tapered to a narrow point, and fitted with a rubber bulb at the top.
pasteur pipette
instrument used to measure mass very precisely
triple beam balance
container that can withstand very high temperatures and is used for metal
crucible
The process of separating components of a
mixture based on different boiling points.
distillation set up
process whereby atoms or molecules in a liquid state (or solid-state if the substance sublimes) gain sufficient energy to enter the gaseous state.
evaporation set up
process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter.
filtratio set up
gas produced in a chemical reaction can be collected by __
water displacement
is a separation process consisting of the separation of a substance from a matrix.
extraction set up
a substance changes from a solid to a gas without ever passing through a liquid phase.
sublimation set up
Dry ice, solid CO2 is an example of
sublimation
The process of collecting a gas produced by a chemical reaction
gas set up collection
Gas may be liquefied and separate.
