Laboratory Apparatus And Their Uses 3v2j1f

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.
