Description
516 23 Micro-Ostwald viscometer is a calibrated capillary instrument designed for manual viscosity measurements in analytical and research laboratories. It is specified with capillary number IIc and constant K = 0,3, enabling kinematic viscosity determination from measured efflux times of small liquid samples under controlled conditions. Calibration for manual operation allows flow times to be converted directly with the stated capillary constant, supporting reproducible results in quality control, method development and teaching environments. The unit is supplied as 1 pc with a net weight of 0,275 kg and a gross weight of 0,275 kg. Manufactured by SI Analytics - a Xylem brand in Germany, this model belongs to the 516 series of micro-Ostwald viscometers. Laboratories working with limited sample volumes benefit from the defined capillary geometry and the convenience of a ready-calibrated constant without needing automated systems. The instrument integrates readily into existing manual workflows for routine fluid characterisation, process samples and reference measurements where classical capillary viscometry remains the preferred approach.
This article is part of Viscometers, in Density & viscosity measurement.

What is this article?
516 23, Micro-Ostwald viscometer, calibrated for manual measurements, Capillary is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand 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.
