What is Micro Technique? Micro-scale and small-scale laboratory experiments are simply experiments that use much smaller amount of chemicals and smaller equipments .

Micro-scale and small-scale laboratory experiments are simply experiments that use much smaller amount of chemicals and smaller equipments .

What is Macro Technique? It is the conventional system of experiment where we use large quantities of chemicals for experiments.

It is the conventional system of experiment where we use large quantities of chemicals for experiments.

From Macro to Micro laboratory Micro-scale experiments use much smaller amount of chemicals and smaller equipments. They have become very popular in chemistry , not only because they reduce the cost of chemicals and reduce the waste disposal problems, but also because they reduce the risks present in the traditional laboratories .

Draw backs of Macro Technique Breakable apparatus Pollution creating Costly equipments Unsafe for students Lack of individuality during experimentation

Breakable apparatus

Pollution creating

Costly equipments

Unsafe for students

Lack of individuality during experimentation

ADVANTAGES OF MICRO TECHNIQUE

IT IS COST SAVING apparatus size is small. cost of micro apparatus is lesser than cost of macro apparatus. small apparatus are safer than big ones.

apparatus size is small.

cost of micro apparatus is lesser than cost of macro apparatus.

small apparatus are safer than big ones.

MORE ECOLOGICALLY SOUND small amount of chemicals is used so there is less wastage and more safety for students as well as for the atmosphere.

SUITABLE FOR ORGANIC AND INORGANIC EXPERIMENTS Faster processes, therefore more suitable for organic experiments. Setups are easily built by the students therefore, more independence. Experimentation can be possible.

MICRO LAB IS VERY SIMPLE Even a fume cupboard is no longer required for most of the experiments. A wall plug is all that is necessary. No water hoses or cooling required and no use of natural gas.

Towards Micro technique

During summer vacations NCERT offered an orientation programme demonstrating usefulness of micro kit developed by it .With the keen interest shown by our principal Mrs. P. Datta and by the consent of NCERT, our chemistry department was able to buy the micro scale kit from NCERT and thus, establishing eco-friendly Micro lab.

IN A NUTSHELL… to make chemistry lab eco-friendly the use of chemicals should be minimized because a lot of pollution takes place which affects not only atmosphere but it also contaminates water .
