Ostwald Viscometer

The Samtech Ostwald Viscometer is a glass U-tube viscometer connected by a capillary tube, with an overall height of 237 mm. It is a classic, time-tested instrument for measuring the viscosity of liquids: a fixed volume of liquid is timed as it flows through the capillary, and the flow time is used to compare viscosity against a reference liquid.

In polymer chemistry, the Ostwald viscometer is widely used to determine the relative molecular mass of a polymer solution from its intrinsic viscosity — a standard method in physical chemistry and polymer science practicals. Its simple, robust design makes it a staple of college and university chemistry labs. As a laboratory glassware manufacturer in Ambala, Samtech produces this viscometer to give consistent, reliable results in routine lab work.
