Pipette















Function:- To measure volume of any liquid.
There are two types of pipettes. One is calibrated pipette,other one is bulb pipette.

Burette



















Function:- To measure and get accurate volume of any liquid.

Flasks

Conical Flask














Function:- To Grow Microbial cultures,To make solutions etc.

Flat bottom flask


















Function:- For making solutions .To produce gasses etc.

Rounded bottom flask


















Function:- For production of gasses ,To make solutions etc.

Volumetric Flasks













Function:- To prepare solutions with definite concentration.

Instruments use to measure weights

Chemical Balance














Function:- To measure weights of chemicals.
How to use:- Keep the balance in a flat surface before taking measurements.

Spring balance
















Function :- To measure weights.
How to use:- Before taking measurements the balance should be in a vertical position.
