Instrument for Lab

Beaker

Beaker

is used for dissolving, mixing, and heating liquids.

Erlenmeyer flask

is used as a reaction vessel and sometimes as a gas generator. It is used to hold liquid or solution to be heated.

volumetric flask

used for diluting and preparing accurate volume of solution.

distilling flask

used for distilling liquids

Florence Flask

is used as a reaction vessel and sometimes as a gas generator. It is used to hold liquid or solution to be heated.

test tube

used as a reaction vessel for experiments involving small amounts of reactants.

porcelain crucible

with cover is used for high temperature ignition.

evaporating dish

used for heating and evaporating solutions.

mortar and pestle

used for mixing and grinding solids.

watch glass

-used for evaporation of volatile liquids, for observing reactions.

- as a container in weighing and as a cover for beakers to avoid evaporation or contamination of the liquid in the beaker

reagent bottle

is used as a container for reagents.
