65 Top Scientific instruments and Their Uses {2022}

Scientific instruments and their uses

Here in this article, we have mentioned 65 important scientific instruments and their uses. The name of these scientific instruments and their functions are important from any exam’s point of view. 

Before we know their names, we should know the meaning of the scientific instruments. A scientific instrument is a device used to scientifically measure/record/indicate the values of any physical or natural phenomenon/events/research. 

The uses of scientific instruments may be as simple as scales, and rulers, and as complex as the uses of particle colliders, radio telescopes, etc. The uses of these instruments depend on many factors and may vary in size, shape, purpose, and complexity.

These scientific devices must be useful for improving your general knowledge and reading about them would be a plus point if you prepare for any competitive examination.
