Berzelius and Erlenmeyer flasks, test tubes, crucibles, cups, etc.
These are of course chemical reactions, for example oxydation.
chemical reactions took place when labrotary experimentories.
an improvised apparatus is an apparatus that functions like the original but lesser in quality because of the alternative or substitute materials used in making it to function
a precipitate is a solid that forms during a chemical reactions
You would use an electron microscope to view a Golgi apparatus.
A microscope is an example of an apparatus used in laboratories to observe tiny objects or organisms at high magnifications.
These are of course chemical reactions, for example oxydation.
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
chemical reactions took place when labrotary experimentories.
You can observe burning, corrosion or precipitation.

vicats apparatus is used for initial setting time of cement.
a device use to prefer some object or apparatus use to observe things in their proper uses
observe it ,when there is a quick reaction...compare the reactions in the problem you've been solving..
A Barton apparatus is a laboratory equipment used for synthesizing organic molecules via radical chemistry. It typically consists of a tube filled with mercury(II) oxide and a UV light source to generate radicals from carboxylic acids. These radicals can be used in various organic reactions to create new compounds.
Infra-red waves are used in night vision apparatus.
