Description
Ostwald viscometer finished in blue enamel is a capillary glass instrument used to determine the relative viscosity of liquids by measuring the time required for a defined volume to flow under gravity. This model is specified with a flow time of 45 s and an instrument constant of 0,022, and it is supplied calibrated for laboratory use. The blue enamel colour provides clear visual distinction on the bench and during immersion procedures. Offered as a single piece with a net weight of 0,123 kg, the viscometer is intended for routine kinematic viscosity work with transparent Newtonian fluids such as solvents, oils and aqueous solutions. From manufacturer Witeg, the device follows the classic Ostwald design that remains a standard reference method in analytical and quality-control environments. Users calculate viscosity from the observed efflux time multiplied by the stated instrument constant, enabling straightforward comparative measurements. The calibrated status supports reproducible results under controlled temperature conditions. The defined constant of 0,022 makes this unit practical for teaching laboratories and industrial QC stations requiring reliable capillary viscometry.

Questions about Viscometer according to Ostwald
What is this article?
Viscometer according to Ostwald is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
