Laboratory apparatus and their uses Dropper -
a small tube having a rubber bulb at one end for drawing up and dispensing drops
of liquid.
beaker - is a simple container for stirring, mixing and heating liquids commonly used in many laboratories.
Trough -
is a piece of laboratory apparatus used for collecting gases, such as hydrogen,
oxygen, and nitrogen.
Gas jar -
is a container used for collecting gas from experiments. It looks like a tube with a
broad base and a broad opening.
Flask -
are all containers or vessels, usually designed to carry a liquid and often made of
glass. The software includes flat bottomed flask, circle bottomed flask, conical flask, pearshaped flask and suction flask.
Flat bottomed - means they can be placed on flat surfaces such as the laboratory bench, or in a fridge or incubator/oven and also can be stirred more easily on a hotplate.
Conical flask - are laboratory vessels that have a wide, flat base and a narrow neck. Test tube -
is usually used to hold the substance in place and that u can observe reactions
taking place.
U tube -
is a glass tube shaped in the form of letter "U" which can be used as a manometer,
and is used in measuring the pressure of liquids.
Pear shape flask -
are made by using very superior and quality raw material
which ensures high durability at its end.
Liebig condenser - are a simple condenser design used to cool and condense hot vapor as part of a distilling apparatus.
Cannula -
is a narrow, flexible plastic tubing used to deliver oxygen through the nostrils of
patients using nasal breathing.
Measuring cylinder - is used to measure the volume solutions, liquids or water. Evaporation dish - is a piece of laboratory glassware used for the evaporation of solids and supernatant fluids, and sometimes to their melting point.
Watch glass -
is a circular, slightly concave piece of glass used in chemistry as a surface to
evaporate a liquid, or as a cover for a beaker.
Acid burette -
is a uniform-bore glass tube with fine gradations and a stopcock at the
bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement.
Alkaline burette -
are simultaneously occupied by the presence of a liquid measuring and
transferring this derailment.
