Ever wonder if there will be no standardization in measurements, it will create chaos in the surrounding and will vary from person to person. So measuring becomes a crucial subject and needs standardization in 1960, the 11th General Conference on Weights and Measures establish The International System of Unit, also known as SI units. In laboratories, measurements are an essential subject and its instruments are the basics of the labs.

The Science Lab manufactures and supplies the measuring instruments which are known for their accuracy. We have a wide variety of spring scales & balances, measuring beakers & flasks, scales, thermometers, calipers, weights & masses, measuring tapes, and many more.
